Chapter 2. Alertmanager [monitoring.coreos.com/v1] Description Alertmanager describes an Alertmanager cluster. Type object Required spec 2.1. Specification Property Type Description apiVersion string APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources kind string Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds metadata ObjectMeta Standard object's metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata spec object Specification of the desired behavior of the Alertmanager cluster. More info: https://github.com/kubernetes/community/blob/master/contributors/devel/sig-architecture/api-conventions.md#spec-and-status status object Most recent observed status of the Alertmanager cluster. Read-only. More info: https://github.com/kubernetes/community/blob/master/contributors/devel/sig-architecture/api-conventions.md#spec-and-status 2.1.1. .spec Description Specification of the desired behavior of the Alertmanager cluster. More info: https://github.com/kubernetes/community/blob/master/contributors/devel/sig-architecture/api-conventions.md#spec-and-status Type object Property Type Description additionalPeers array (string) AdditionalPeers allows injecting a set of additional Alertmanagers to peer with to form a highly available cluster. affinity object If specified, the pod's scheduling constraints. alertmanagerConfigMatcherStrategy object The AlertmanagerConfigMatcherStrategy defines how AlertmanagerConfig objects match the alerts. In the future more options may be added. alertmanagerConfigNamespaceSelector object Namespaces to be selected for AlertmanagerConfig discovery. If nil, only check own namespace. alertmanagerConfigSelector object AlertmanagerConfigs to be selected for to merge and configure Alertmanager with. alertmanagerConfiguration object alertmanagerConfiguration specifies the configuration of Alertmanager. If defined, it takes precedence over the configSecret field. This is an experimental feature , it may change in any upcoming release in a breaking way. automountServiceAccountToken boolean AutomountServiceAccountToken indicates whether a service account token should be automatically mounted in the pod. If the service account has automountServiceAccountToken: true , set the field to false to opt out of automounting API credentials. baseImage string Base image that is used to deploy pods, without tag. Deprecated: use 'image' instead. clusterAdvertiseAddress string ClusterAdvertiseAddress is the explicit address to advertise in cluster. Needs to be provided for non RFC1918 [1] (public) addresses. [1] RFC1918: https://tools.ietf.org/html/rfc1918 clusterGossipInterval string Interval between gossip attempts. clusterLabel string Defines the identifier that uniquely identifies the Alertmanager cluster. You should only set it when the Alertmanager cluster includes Alertmanager instances which are external to this Alertmanager resource. In practice, the addresses of the external instances are provided via the .spec.additionalPeers field. clusterPeerTimeout string Timeout for cluster peering. clusterPushpullInterval string Interval between pushpull attempts. configMaps array (string) ConfigMaps is a list of ConfigMaps in the same namespace as the Alertmanager object, which shall be mounted into the Alertmanager Pods. Each ConfigMap is added to the StatefulSet definition as a volume named configmap-<configmap-name> . The ConfigMaps are mounted into /etc/alertmanager/configmaps/<configmap-name> in the 'alertmanager' container. configSecret string ConfigSecret is the name of a Kubernetes Secret in the same namespace as the Alertmanager object, which contains the configuration for this Alertmanager instance. If empty, it defaults to alertmanager-<alertmanager-name> . The Alertmanager configuration should be available under the alertmanager.yaml key. Additional keys from the original secret are copied to the generated secret and mounted into the /etc/alertmanager/config directory in the alertmanager container. If either the secret or the alertmanager.yaml key is missing, the operator provisions a minimal Alertmanager configuration with one empty receiver (effectively dropping alert notifications). containers array Containers allows injecting additional containers. This is meant to allow adding an authentication proxy to an Alertmanager pod. Containers described here modify an operator generated container if they share the same name and modifications are done via a strategic merge patch. The current container names are: alertmanager and config-reloader . Overriding containers is entirely outside the scope of what the maintainers will support and by doing so, you accept that this behaviour may break at any time without notice. containers[] object A single application container that you want to run within a pod. enableFeatures array (string) Enable access to Alertmanager feature flags. By default, no features are enabled. Enabling features which are disabled by default is entirely outside the scope of what the maintainers will support and by doing so, you accept that this behaviour may break at any time without notice. It requires Alertmanager >= 0.27.0. externalUrl string The external URL the Alertmanager instances will be available under. This is necessary to generate correct URLs. This is necessary if Alertmanager is not served from root of a DNS name. forceEnableClusterMode boolean ForceEnableClusterMode ensures Alertmanager does not deactivate the cluster mode when running with a single replica. Use case is e.g. spanning an Alertmanager cluster across Kubernetes clusters with a single replica in each. hostAliases array Pods' hostAliases configuration hostAliases[] object HostAlias holds the mapping between IP and hostnames that will be injected as an entry in the pod's hosts file. image string Image if specified has precedence over baseImage, tag and sha combinations. Specifying the version is still necessary to ensure the Prometheus Operator knows what version of Alertmanager is being configured. imagePullPolicy string Image pull policy for the 'alertmanager', 'init-config-reloader' and 'config-reloader' containers. See https://kubernetes.io/docs/concepts/containers/images/#image-pull-policy for more details. imagePullSecrets array An optional list of references to secrets in the same namespace to use for pulling prometheus and alertmanager images from registries see http://kubernetes.io/docs/user-guide/images#specifying-imagepullsecrets-on-a-pod imagePullSecrets[] object LocalObjectReference contains enough information to let you locate the referenced object inside the same namespace. initContainers array InitContainers allows adding initContainers to the pod definition. Those can be used to e.g. fetch secrets for injection into the Alertmanager configuration from external sources. Any errors during the execution of an initContainer will lead to a restart of the Pod. More info: https://kubernetes.io/docs/concepts/workloads/pods/init-containers/ InitContainers described here modify an operator generated init containers if they share the same name and modifications are done via a strategic merge patch. The current init container name is: init-config-reloader . Overriding init containers is entirely outside the scope of what the maintainers will support and by doing so, you accept that this behaviour may break at any time without notice. initContainers[] object A single application container that you want to run within a pod. listenLocal boolean ListenLocal makes the Alertmanager server listen on loopback, so that it does not bind against the Pod IP. Note this is only for the Alertmanager UI, not the gossip communication. logFormat string Log format for Alertmanager to be configured with. logLevel string Log level for Alertmanager to be configured with. minReadySeconds integer Minimum number of seconds for which a newly created pod should be ready without any of its container crashing for it to be considered available. Defaults to 0 (pod will be considered available as soon as it is ready) This is an alpha field from kubernetes 1.22 until 1.24 which requires enabling the StatefulSetMinReadySeconds feature gate. nodeSelector object (string) Define which Nodes the Pods are scheduled on. paused boolean If set to true all actions on the underlying managed objects are not goint to be performed, except for delete actions. podMetadata object PodMetadata configures labels and annotations which are propagated to the Alertmanager pods. The following items are reserved and cannot be overridden: * "alertmanager" label, set to the name of the Alertmanager instance. * "app.kubernetes.io/instance" label, set to the name of the Alertmanager instance. * "app.kubernetes.io/managed-by" label, set to "prometheus-operator". * "app.kubernetes.io/name" label, set to "alertmanager". * "app.kubernetes.io/version" label, set to the Alertmanager version. * "kubectl.kubernetes.io/default-container" annotation, set to "alertmanager". portName string Port name used for the pods and governing service. Defaults to web . priorityClassName string Priority class assigned to the Pods replicas integer Size is the expected size of the alertmanager cluster. The controller will eventually make the size of the running cluster equal to the expected size. resources object Define resources requests and limits for single Pods. retention string Time duration Alertmanager shall retain data for. Default is '120h', and must match the regular expression [0-9]+(ms|s|m|h) (milliseconds seconds minutes hours). routePrefix string The route prefix Alertmanager registers HTTP handlers for. This is useful, if using ExternalURL and a proxy is rewriting HTTP routes of a request, and the actual ExternalURL is still true, but the server serves requests under a different route prefix. For example for use with kubectl proxy . secrets array (string) Secrets is a list of Secrets in the same namespace as the Alertmanager object, which shall be mounted into the Alertmanager Pods. Each Secret is added to the StatefulSet definition as a volume named secret-<secret-name> . The Secrets are mounted into /etc/alertmanager/secrets/<secret-name> in the 'alertmanager' container. securityContext object SecurityContext holds pod-level security attributes and common container settings. This defaults to the default PodSecurityContext. serviceAccountName string ServiceAccountName is the name of the ServiceAccount to use to run the Prometheus Pods. sha string SHA of Alertmanager container image to be deployed. Defaults to the value of version . Similar to a tag, but the SHA explicitly deploys an immutable container image. Version and Tag are ignored if SHA is set. Deprecated: use 'image' instead. The image digest can be specified as part of the image URL. storage object Storage is the definition of how storage will be used by the Alertmanager instances. tag string Tag of Alertmanager container image to be deployed. Defaults to the value of version . Version is ignored if Tag is set. Deprecated: use 'image' instead. The image tag can be specified as part of the image URL. tolerations array If specified, the pod's tolerations. tolerations[] object The pod this Toleration is attached to tolerates any taint that matches the triple <key,value,effect> using the matching operator <operator>. topologySpreadConstraints array If specified, the pod's topology spread constraints. topologySpreadConstraints[] object TopologySpreadConstraint specifies how to spread matching pods among the given topology. version string Version the cluster should be on. volumeMounts array VolumeMounts allows configuration of additional VolumeMounts on the output StatefulSet definition. VolumeMounts specified will be appended to other VolumeMounts in the alertmanager container, that are generated as a result of StorageSpec objects. volumeMounts[] object VolumeMount describes a mounting of a Volume within a container. volumes array Volumes allows configuration of additional volumes on the output StatefulSet definition. Volumes specified will be appended to other volumes that are generated as a result of StorageSpec objects. volumes[] object Volume represents a named volume in a pod that may be accessed by any container in the pod. web object Defines the web command line flags when starting Alertmanager. 2.1.2. .spec.affinity Description If specified, the pod's scheduling constraints.

This is meant to allow adding an authentication proxy to an Alertmanager pod. Containers described here modify an operator generated container if they share the same name and modifications are done via a strategic merge patch. The current container names are: alertmanager and config-reloader . Overriding containers is entirely outside the scope of what the maintainers will support and by doing so, you accept that this behaviour may break at any time without notice. Type array 2.1.95. .spec.containers[] Description A single application container that you want to run within a pod. Type object Required name Property Type Description args array (string) Arguments to the entrypoint. The container image's CMD is used if this is not provided. Variable references USD(VAR_NAME) are expanded using the container's environment. If a variable cannot be resolved, the reference in the input string will be unchanged. Double are reduced to a single USD, which allows for escaping the USD(VAR_NAME) syntax: i.e. "(VAR_NAME)" will produce the string literal "USD(VAR_NAME)". Escaped references will never be expanded, regardless of whether the variable exists or not. Cannot be updated. More info: https://kubernetes.io/docs/tasks/inject-data-application/define-command-argument-container/#running-a-command-in-a-shell command array (string) Entrypoint array. Not executed within a shell. The container image's ENTRYPOINT is used if this is not provided. Variable references USD(VAR_NAME) are expanded using the container's environment. If a variable cannot be resolved, the reference in the input string will be unchanged. Double are reduced to a single USD, which allows for escaping the USD(VAR_NAME) syntax: i.e. "(VAR_NAME)" will produce the string literal "USD(VAR_NAME)". Escaped references will never be expanded, regardless of whether the variable exists or not. Cannot be updated. More info: https://kubernetes.io/docs/tasks/inject-data-application/define-command-argument-container/#running-a-command-in-a-shell env array List of environment variables to set in the container. Cannot be updated. env[] object EnvVar represents an environment variable present in a Container. envFrom array List of sources to populate environment variables in the container. The keys defined within a source must be a C_IDENTIFIER. All invalid keys will be reported as an event when the container is starting. When a key exists in multiple sources, the value associated with the last source will take precedence. Values defined by an Env with a duplicate key will take precedence. Cannot be updated. envFrom[] object EnvFromSource represents the source of a set of ConfigMaps image string Container image name. More info: https://kubernetes.io/docs/concepts/containers/images This field is optional to allow higher level config management to default or override container images in workload controllers like Deployments and StatefulSets. imagePullPolicy string Image pull policy. One of Always, Never, IfNotPresent. Defaults to Always if :latest tag is specified, or IfNotPresent otherwise. Cannot be updated. More info: https://kubernetes.io/docs/concepts/containers/images#updating-images lifecycle object Actions that the management system should take in response to container lifecycle events. Cannot be updated. livenessProbe object Periodic probe of container liveness. Container will be restarted if the probe fails. Cannot be updated. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes name string Name of the container specified as a DNS_LABEL. Each container in a pod must have a unique name (DNS_LABEL). Cannot be updated. ports array List of ports to expose from the container. Not specifying a port here DOES NOT prevent that port from being exposed. Any port which is listening on the default "0.0.0.0" address inside a container will be accessible from the network. Modifying this array with strategic merge patch may corrupt the data. For more information See https://github.com/kubernetes/kubernetes/issues/108255 . Cannot be updated. ports[] object ContainerPort represents a network port in a single container. readinessProbe object Periodic probe of container service readiness. Container will be removed from service endpoints if the probe fails. Cannot be updated. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes resizePolicy array Resources resize policy for the container. resizePolicy[] object ContainerResizePolicy represents resource resize policy for the container. resources object Compute Resources required by this container. Cannot be updated. More info: https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/ restartPolicy string RestartPolicy defines the restart behavior of individual containers in a pod. This field may only be set for init containers, and the only allowed value is "Always". For non-init containers or when this field is not specified, the restart behavior is defined by the Pod's restart policy and the container type. Setting the RestartPolicy as "Always" for the init container will have the following effect: this init container will be continually restarted on exit until all regular containers have terminated. Once all regular containers have completed, all init containers with restartPolicy "Always" will be shut down. This lifecycle differs from normal init containers and is often referred to as a "sidecar" container. Although this init container still starts in the init container sequence, it does not wait for the container to complete before proceeding to the init container. Instead, the init container starts immediately after this init container is started, or after any startupProbe has successfully completed. securityContext object SecurityContext defines the security options the container should be run with. If set, the fields of SecurityContext override the equivalent fields of PodSecurityContext. More info: https://kubernetes.io/docs/tasks/configure-pod-container/security-context/ startupProbe object StartupProbe indicates that the Pod has successfully initialized. If specified, no other probes are executed until this completes successfully. If this probe fails, the Pod will be restarted, just as if the livenessProbe failed. This can be used to provide different probe parameters at the beginning of a Pod's lifecycle, when it might take a long time to load data or warm a cache, than during steady-state operation. This cannot be updated. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes stdin boolean Whether this container should allocate a buffer for stdin in the container runtime. If this is not set, reads from stdin in the container will always result in EOF. Default is false. stdinOnce boolean Whether the container runtime should close the stdin channel after it has been opened by a single attach. When stdin is true the stdin stream will remain open across multiple attach sessions. If stdinOnce is set to true, stdin is opened on container start, is empty until the first client attaches to stdin, and then remains open and accepts data until the client disconnects, at which time stdin is closed and remains closed until the container is restarted. If this flag is false, a container processes that reads from stdin will never receive an EOF. Default is false terminationMessagePath string Optional: Path at which the file to which the container's termination message will be written is mounted into the container's filesystem. Message written is intended to be brief final status, such as an assertion failure message. Will be truncated by the node if greater than 4096 bytes. The total message length across all containers will be limited to 12kb. Defaults to /dev/termination-log. Cannot be updated. terminationMessagePolicy string Indicate how the termination message should be populated. File will use the contents of terminationMessagePath to populate the container status message on both success and failure. FallbackToLogsOnError will use the last chunk of container log output if the termination message file is empty and the container exited with an error. The log output is limited to 2048 bytes or 80 lines, whichever is smaller. Defaults to File. Cannot be updated. tty boolean Whether this container should allocate a TTY for itself, also requires 'stdin' to be true. Default is false. volumeDevices array volumeDevices is the list of block devices to be used by the container. volumeDevices[] object volumeDevice describes a mapping of a raw block device within a container. volumeMounts array Pod volumes to mount into the container's filesystem. Cannot be updated. volumeMounts[] object VolumeMount describes a mounting of a Volume within a container. workingDir string Container's working directory. If not specified, the container runtime's default will be used, which might be configured in the container image. Cannot be updated. 2.1.96. .spec.containers[].env Description List of environment variables to set in the container. Cannot be updated. Type array 2.1.97. .spec.containers[].env[] Description EnvVar represents an environment variable present in a Container. Type object Required name Property Type Description name string Name of the environment variable. Must be a C_IDENTIFIER. value string Variable references USD(VAR_NAME) are expanded using the previously defined environment variables in the container and any service environment variables. If a variable cannot be resolved, the reference in the input string will be unchanged. Double are reduced to a single USD, which allows for escaping the USD(VAR_NAME) syntax: i.e. "(VAR_NAME)" will produce the string literal "USD(VAR_NAME)". Escaped references will never be expanded, regardless of whether the variable exists or not. Defaults to "". valueFrom object Source for the environment variable's value. Cannot be used if value is not empty. 2.1.98. .spec.containers[].env[].valueFrom Description Source for the environment variable's value. Cannot be used if value is not empty. Type object Property Type Description configMapKeyRef object Selects a key of a ConfigMap. fieldRef object Selects a field of the pod: supports metadata.name, metadata.namespace, metadata.labels['<KEY>'] , metadata.annotations['<KEY>'] , spec.nodeName, spec.serviceAccountName, status.hostIP, status.podIP, status.podIPs. resourceFieldRef object Selects a resource of the container: only resources limits and requests (limits.cpu, limits.memory, limits.ephemeral-storage, requests.cpu, requests.memory and requests.ephemeral-storage) are currently supported. secretKeyRef object Selects a key of a secret in the pod's namespace 2.1.99. .spec.containers[].env[].valueFrom.configMapKeyRef Description Selects a key of a ConfigMap.

Each container in a pod must have a unique name (DNS_LABEL). Cannot be updated. ports array List of ports to expose from the container. Not specifying a port here DOES NOT prevent that port from being exposed. Any port which is listening on the default "0.0.0.0" address inside a container will be accessible from the network. Modifying this array with strategic merge patch may corrupt the data. For more information See https://github.com/kubernetes/kubernetes/issues/108255 .

Cannot be updated. More info: https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/ restartPolicy string RestartPolicy defines the restart behavior of individual containers in a pod. This field may only be set for init containers, and the only allowed value is "Always". For non-init containers or when this field is not specified, the restart behavior is defined by the Pod's restart policy and the container type. Setting the RestartPolicy as "Always" for the init container will have the following effect: this init container will be continually restarted on exit until all regular containers have terminated. Once all regular containers have completed, all init containers with restartPolicy "Always" will be shut down. This lifecycle differs from normal init containers and is often referred to as a "sidecar" container. Although this init container still starts in the init container sequence, it does not wait for the container to complete before proceeding to the init container. Instead, the init container starts immediately after this init container is started, or after any startupProbe has successfully completed. securityContext object SecurityContext defines the security options the container should be run with. If set, the fields of SecurityContext override the equivalent fields of PodSecurityContext. More info: https://kubernetes.io/docs/tasks/configure-pod-container/security-context/ startupProbe object StartupProbe indicates that the Pod has successfully initialized. If specified, no other probes are executed until this completes successfully. If this probe fails, the Pod will be restarted, just as if the livenessProbe failed. This can be used to provide different probe parameters at the beginning of a Pod's lifecycle, when it might take a long time to load data or warm a cache, than during steady-state operation. This cannot be updated. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes stdin boolean Whether this container should allocate a buffer for stdin in the container runtime. If this is not set, reads from stdin in the container will always result in EOF. Default is false. stdinOnce boolean Whether the container runtime should close the stdin channel after it has been opened by a single attach. When stdin is true the stdin stream will remain open across multiple attach sessions. If stdinOnce is set to true, stdin is opened on container start, is empty until the first client attaches to stdin, and then remains open and accepts data until the client disconnects, at which time stdin is closed and remains closed until the container is restarted. If this flag is false, a container processes that reads from stdin will never receive an EOF. Default is false terminationMessagePath string Optional: Path at which the file to which the container's termination message will be written is mounted into the container's filesystem. Message written is intended to be brief final status, such as an assertion failure message. Will be truncated by the node if greater than 4096 bytes. The total message length across all containers will be limited to 12kb. Defaults to /dev/termination-log. Cannot be updated. terminationMessagePolicy string Indicate how the termination message should be populated. File will use the contents of terminationMessagePath to populate the container status message on both success and failure. FallbackToLogsOnError will use the last chunk of container log output if the termination message file is empty and the container exited with an error. The log output is limited to 2048 bytes or 80 lines, whichever is smaller. Defaults to File. Cannot be updated. tty boolean Whether this container should allocate a TTY for itself, also requires 'stdin' to be true.

Defaults to false. recursiveReadOnly string RecursiveReadOnly specifies whether read-only mounts should be handled recursively. If ReadOnly is false, this field has no meaning and must be unspecified. If ReadOnly is true, and this field is set to Disabled, the mount is not made recursively read-only. If this field is set to IfPossible, the mount is made recursively read-only, if it is supported by the container runtime. If this field is set to Enabled, the mount is made recursively read-only if it is supported by the container runtime, otherwise the pod will not be started and an error will be generated to indicate the reason. If this field is set to IfPossible or Enabled, MountPropagation must be set to None (or be unspecified, which defaults to None). If this field is not specified, it is treated as an equivalent of Disabled. subPath string Path within the volume from which the container's volume should be mounted.

If true, the Kubelet will validate the image at runtime to ensure that it does not run as UID 0 (root) and fail to start the container if it does. If unset or false, no such validation will be performed. May also be set in SecurityContext. If set in both SecurityContext and PodSecurityContext, the value specified in SecurityContext takes precedence. runAsUser integer The UID to run the entrypoint of the container process.

For lower versions, starting with k8s 1.19, it requires enabling the GenericEphemeralVolume feature gate. More info: https://kubernetes.io/docs/concepts/storage/ephemeral-volumes/#generic-ephemeral-volumes volumeClaimTemplate object Defines the PVC spec to be used by the Prometheus StatefulSets. The easiest way to use a volume that cannot be automatically provisioned is to use a label selector alongside manually created PersistentVolumes. 2.1.242. .spec.storage.emptyDir Description EmptyDirVolumeSource to be used by the StatefulSet. If specified, it takes precedence over ephemeral and volumeClaimTemplate . More info: https://kubernetes.io/docs/concepts/storage/volumes/#emptydir Type object Property Type Description medium string medium represents what type of storage medium should back this directory.

This is a beta field in k8s 1.21 and GA in 1.15. For lower versions, starting with k8s 1.19, it requires enabling the GenericEphemeralVolume feature gate. More info: https://kubernetes.io/docs/concepts/storage/ephemeral-volumes/#generic-ephemeral-volumes Type object Property Type Description volumeClaimTemplate object Will be used to create a stand-alone PVC to provision the volume. The pod in which this EphemeralVolumeSource is embedded will be the owner of the PVC, i.e. the PVC will be deleted together with the pod. The name of the PVC will be <pod name>-<volume name> where <volume name> is the name from the PodSpec.Volumes array entry. Pod validation will reject the pod if the concatenated name is not valid for a PVC (for example, too long). An existing PVC with that name that is not owned by the pod will not be used for the pod to avoid using an unrelated volume by mistake. Starting the pod is then blocked until the unrelated PVC is removed. If such a pre-created PVC is meant to be used by the pod, the PVC has to updated with an owner reference to the pod once the pod exists. Normally this should not be necessary, but it may be useful when manually reconstructing a broken cluster. This field is read-only and no changes will be made by Kubernetes to the PVC after it has been created. Required, must not be nil. 2.1.244. .spec.storage.ephemeral.volumeClaimTemplate Description Will be used to create a stand-alone PVC to provision the volume. The pod in which this EphemeralVolumeSource is embedded will be the owner of the PVC, i.e. the PVC will be deleted together with the pod. The name of the PVC will be <pod name>-<volume name> where <volume name> is the name from the PodSpec.Volumes array entry.

An existing PVC with that name that is not owned by the pod will not be used for the pod to avoid using an unrelated volume by mistake. Starting the pod is then blocked until the unrelated PVC is removed. If such a pre-created PVC is meant to be used by the pod, the PVC has to updated with an owner reference to the pod once the pod exists. Normally this should not be necessary, but it may be useful when manually reconstructing a broken cluster. This field is read-only and no changes will be made by Kubernetes to the PVC after it has been created. Required, must not be nil. Type object Required spec Property Type Description metadata object May contain labels and annotations that will be copied into the PVC when creating it. No other fields are allowed and will be rejected during validation. spec object The specification for the PersistentVolumeClaim.

The same fields as in a PersistentVolumeClaim are also valid here. 2.1.245. .spec.storage.ephemeral.volumeClaimTemplate.metadata Description May contain labels and annotations that will be copied into the PVC when creating it. No other fields are allowed and will be rejected during validation. Type object 2.1.246. .spec.storage.ephemeral.volumeClaimTemplate.spec Description The specification for the PersistentVolumeClaim. The entire content is copied unchanged into the PVC that gets created from this template. The same fields as in a PersistentVolumeClaim are also valid here. Type object Property Type Description accessModes array (string) accessModes contains the desired access modes the volume should have. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#access-modes-1 dataSource object dataSource field can be used to specify either: * An existing VolumeSnapshot object (snapshot.storage.k8s.io/VolumeSnapshot) * An existing PVC (PersistentVolumeClaim) If the provisioner or an external controller can support the specified data source, it will create a new volume based on the contents of the specified data source. When the AnyVolumeDataSource feature gate is enabled, dataSource contents will be copied to dataSourceRef, and dataSourceRef contents will be copied to dataSource when dataSourceRef.namespace is not specified. If the namespace is specified, then dataSourceRef will not be copied to dataSource. dataSourceRef object dataSourceRef specifies the object from which to populate the volume with data, if a non-empty volume is desired. This may be any object from a non-empty API group (non core object) or a PersistentVolumeClaim object. When this field is specified, volume binding will only succeed if the type of the specified object matches some installed volume populator or dynamic provisioner. This field will replace the functionality of the dataSource field and as such if both fields are non-empty, they must have the same value. For backwards compatibility, when namespace isn't specified in dataSourceRef, both fields (dataSource and dataSourceRef) will be set to the same value automatically if one of them is empty and the other is non-empty. When namespace is specified in dataSourceRef, dataSource isn't set to the same value and must be empty. There are three important differences between dataSource and dataSourceRef: * While dataSource only allows two specific types of objects, dataSourceRef allows any non-core object, as well as PersistentVolumeClaim objects. * While dataSource ignores disallowed values (dropping them), dataSourceRef preserves all values, and generates an error if a disallowed value is specified. * While dataSource only allows local objects, dataSourceRef allows objects in any namespaces. (Beta) Using this field requires the AnyVolumeDataSource feature gate to be enabled. (Alpha) Using the namespace field of dataSourceRef requires the CrossNamespaceVolumeDataSource feature gate to be enabled. resources object resources represents the minimum resources the volume should have. If RecoverVolumeExpansionFailure feature is enabled users are allowed to specify resource requirements that are lower than value but must still be higher than capacity recorded in the status field of the claim. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#resources selector object selector is a label query over volumes to consider for binding. storageClassName string storageClassName is the name of the StorageClass required by the claim. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#class-1 volumeAttributesClassName string volumeAttributesClassName may be used to set the VolumeAttributesClass used by this claim. If specified, the CSI driver will create or update the volume with the attributes defined in the corresponding VolumeAttributesClass. This has a different purpose than storageClassName, it can be changed after the claim is created. An empty string value means that no VolumeAttributesClass will be applied to the claim but it's not allowed to reset this field to empty string once it is set. If unspecified and the PersistentVolumeClaim is unbound, the default VolumeAttributesClass will be set by the persistentvolume controller if it exists. If the resource referred to by volumeAttributesClass does not exist, this PersistentVolumeClaim will be set to a Pending state, as reflected by the modifyVolumeStatus field, until such as a resource exists. More info: https://kubernetes.io/docs/concepts/storage/volume-attributes-classes/ (Alpha) Using this field requires the VolumeAttributesClass feature gate to be enabled. volumeMode string volumeMode defines what type of volume is required by the claim. Value of Filesystem is implied when not included in claim spec. volumeName string volumeName is the binding reference to the PersistentVolume backing this claim. 2.1.247. .spec.storage.ephemeral.volumeClaimTemplate.spec.dataSource Description dataSource field can be used to specify either: * An existing VolumeSnapshot object (snapshot.storage.k8s.io/VolumeSnapshot) * An existing PVC (PersistentVolumeClaim) If the provisioner or an external controller can support the specified data source, it will create a new volume based on the contents of the specified data source. When the AnyVolumeDataSource feature gate is enabled, dataSource contents will be copied to dataSourceRef, and dataSourceRef contents will be copied to dataSource when dataSourceRef.namespace is not specified. If the namespace is specified, then dataSourceRef will not be copied to dataSource.

When the AnyVolumeDataSource feature gate is enabled, dataSource contents will be copied to dataSourceRef, and dataSourceRef contents will be copied to dataSource when dataSourceRef.namespace is not specified. If the namespace is specified, then dataSourceRef will not be copied to dataSource. dataSourceRef object dataSourceRef specifies the object from which to populate the volume with data, if a non-empty volume is desired. This may be any object from a non-empty API group (non core object) or a PersistentVolumeClaim object. When this field is specified, volume binding will only succeed if the type of the specified object matches some installed volume populator or dynamic provisioner. This field will replace the functionality of the dataSource field and as such if both fields are non-empty, they must have the same value. For backwards compatibility, when namespace isn't specified in dataSourceRef, both fields (dataSource and dataSourceRef) will be set to the same value automatically if one of them is empty and the other is non-empty. When namespace is specified in dataSourceRef, dataSource isn't set to the same value and must be empty. There are three important differences between dataSource and dataSourceRef: * While dataSource only allows two specific types of objects, dataSourceRef allows any non-core object, as well as PersistentVolumeClaim objects. * While dataSource ignores disallowed values (dropping them), dataSourceRef preserves all values, and generates an error if a disallowed value is specified. * While dataSource only allows local objects, dataSourceRef allows objects in any namespaces.

If specified, the CSI driver will create or update the volume with the attributes defined in the corresponding VolumeAttributesClass. This has a different purpose than storageClassName, it can be changed after the claim is created. An empty string value means that no VolumeAttributesClass will be applied to the claim but it's not allowed to reset this field to empty string once it is set. If unspecified and the PersistentVolumeClaim is unbound, the default VolumeAttributesClass will be set by the persistentvolume controller if it exists. If the resource referred to by volumeAttributesClass does not exist, this PersistentVolumeClaim will be set to a Pending state, as reflected by the modifyVolumeStatus field, until such as a resource exists. More info: https://kubernetes.io/docs/concepts/storage/volume-attributes-classes/ (Alpha) Using this field requires the VolumeAttributesClass feature gate to be enabled. volumeMode string volumeMode defines what type of volume is required by the claim.

Type object Property Type Description matchExpressions array matchExpressions is a list of label selector requirements. The requirements are ANDed. matchExpressions[] object A label selector requirement is a selector that contains values, a key, and an operator that relates the key and values. matchLabels object (string) matchLabels is a map of {key,value} pairs. A single {key,value} in the matchLabels map is equivalent to an element of matchExpressions, whose key field is "key", the operator is "In", and the values array contains only "value".

Type array 2.1.261. .spec.storage.volumeClaimTemplate.spec.selector.matchExpressions[] Description A label selector requirement is a selector that contains values, a key, and an operator that relates the key and values. Type object Required key operator Property Type Description key string key is the label key that the selector applies to. operator string operator represents a key's relationship to a set of values. Valid operators are In, NotIn, Exists and DoesNotExist. values array (string) values is an array of string values. If the operator is In or NotIn, the values array must be non-empty. If the operator is Exists or DoesNotExist, the values array must be empty. This array is replaced during a strategic merge patch. 2.1.262. .spec.storage.volumeClaimTemplate.status Description Deprecated: this field is never set. Type object Property Type Description accessModes array (string) accessModes contains the actual access modes the volume backing the PVC has. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#access-modes-1 allocatedResourceStatuses object (string) allocatedResourceStatuses stores status of resource being resized for the given PVC. Key names follow standard Kubernetes label syntax. Valid values are either: * Un-prefixed keys: - storage - the capacity of the volume. * Custom resources must use implementation-defined prefixed names such as "example.com/my-custom-resource" Apart from above values - keys that are unprefixed or have kubernetes.io prefix are considered reserved and hence may not be used. ClaimResourceStatus can be in any of following states: - ControllerResizeInProgress: State set when resize controller starts resizing the volume in control-plane. - ControllerResizeFailed: State set when resize has failed in resize controller with a terminal error. - NodeResizePending: State set when resize controller has finished resizing the volume but further resizing of volume is needed on the node. - NodeResizeInProgress: State set when kubelet starts resizing the volume. - NodeResizeFailed: State set when resizing has failed in kubelet with a terminal error. Transient errors don't set NodeResizeFailed. For example: if expanding a PVC for more capacity - this field can be one of the following states: - pvc.status.allocatedResourceStatus['storage'] = "ControllerResizeInProgress" - pvc.status.allocatedResourceStatus['storage'] = "ControllerResizeFailed" - pvc.status.allocatedResourceStatus['storage'] = "NodeResizePending" - pvc.status.allocatedResourceStatus['storage'] = "NodeResizeInProgress" - pvc.status.allocatedResourceStatus['storage'] = "NodeResizeFailed" When this field is not set, it means that no resize operation is in progress for the given PVC. A controller that receives PVC update with previously unknown resourceName or ClaimResourceStatus should ignore the update for the purpose it was designed. For example - a controller that only is responsible for resizing capacity of the volume, should ignore PVC updates that change other valid resources associated with PVC. This is an alpha field and requires enabling RecoverVolumeExpansionFailure feature. allocatedResources integer-or-string allocatedResources tracks the resources allocated to a PVC including its capacity. Key names follow standard Kubernetes label syntax. Valid values are either: * Un-prefixed keys: - storage - the capacity of the volume. * Custom resources must use implementation-defined prefixed names such as "example.com/my-custom-resource" Apart from above values - keys that are unprefixed or have kubernetes.io prefix are considered reserved and hence may not be used. Capacity reported here may be larger than the actual capacity when a volume expansion operation is requested. For storage quota, the larger value from allocatedResources and PVC.spec.resources is used. If allocatedResources is not set, PVC.spec.resources alone is used for quota calculation. If a volume expansion capacity request is lowered, allocatedResources is only lowered if there are no expansion operations in progress and if the actual volume capacity is equal or lower than the requested capacity. A controller that receives PVC update with previously unknown resourceName should ignore the update for the purpose it was designed. For example - a controller that only is responsible for resizing capacity of the volume, should ignore PVC updates that change other valid resources associated with PVC. This is an alpha field and requires enabling RecoverVolumeExpansionFailure feature. capacity integer-or-string capacity represents the actual resources of the underlying volume. conditions array conditions is the current Condition of persistent volume claim. If underlying persistent volume is being resized then the Condition will be set to 'Resizing'. conditions[] object PersistentVolumeClaimCondition contains details about state of pvc currentVolumeAttributesClassName string currentVolumeAttributesClassName is the current name of the VolumeAttributesClass the PVC is using. When unset, there is no VolumeAttributeClass applied to this PersistentVolumeClaim This is an alpha field and requires enabling VolumeAttributesClass feature. modifyVolumeStatus object ModifyVolumeStatus represents the status object of ControllerModifyVolume operation. When this is unset, there is no ModifyVolume operation being attempted. This is an alpha field and requires enabling VolumeAttributesClass feature. phase string phase represents the current phase of PersistentVolumeClaim. 2.1.263. .spec.storage.volumeClaimTemplate.status.conditions Description conditions is the current Condition of persistent volume claim. If underlying persistent volume is being resized then the Condition will be set to 'Resizing'. Type array 2.1.264. .spec.storage.volumeClaimTemplate.status.conditions[] Description PersistentVolumeClaimCondition contains details about state of pvc Type object Required status type Property Type Description lastProbeTime string lastProbeTime is the time we probed the condition. lastTransitionTime string lastTransitionTime is the time the condition transitioned from one status to another. message string message is the human-readable message indicating details about last transition. reason string reason is a unique, this should be a short, machine understandable string that gives the reason for condition's last transition. If it reports "Resizing" that means the underlying persistent volume is being resized. status string type string PersistentVolumeClaimConditionType is a valid value of PersistentVolumeClaimCondition.Type 2.1.265. .spec.storage.volumeClaimTemplate.status.modifyVolumeStatus Description ModifyVolumeStatus represents the status object of ControllerModifyVolume operation. When this is unset, there is no ModifyVolume operation being attempted. This is an alpha field and requires enabling VolumeAttributesClass feature. Type object Required status Property Type Description status string status is the status of the ControllerModifyVolume operation. It can be in any of following states: - Pending Pending indicates that the PersistentVolumeClaim cannot be modified due to unmet requirements, such as the specified VolumeAttributesClass not existing. - InProgress InProgress indicates that the volume is being modified. - Infeasible Infeasible indicates that the request has been rejected as invalid by the CSI driver. To resolve the error, a valid VolumeAttributesClass needs to be specified. Note: New statuses can be added in the future. Consumers should check for unknown statuses and fail appropriately. targetVolumeAttributesClassName string targetVolumeAttributesClassName is the name of the VolumeAttributesClass the PVC currently being reconciled 2.1.266. .spec.tolerations Description If specified, the pod's tolerations. Type array 2.1.267. .spec.tolerations[] Description The pod this Toleration is attached to tolerates any taint that matches the triple <key,value,effect> using the matching operator <operator>. Type object Property Type Description effect string Effect indicates the taint effect to match. Empty means match all taint effects. When specified, allowed values are NoSchedule, PreferNoSchedule and NoExecute. key string Key is the taint key that the toleration applies to. Empty means match all taint keys. If the key is empty, operator must be Exists; this combination means to match all values and all keys. operator string Operator represents a key's relationship to the value. Valid operators are Exists and Equal. Defaults to Equal. Exists is equivalent to wildcard for value, so that a pod can tolerate all taints of a particular category. tolerationSeconds integer TolerationSeconds represents the period of time the toleration (which must be of effect NoExecute, otherwise this field is ignored) tolerates the taint. By default, it is not set, which means tolerate the taint forever (do not evict). Zero and negative values will be treated as 0 (evict immediately) by the system. value string Value is the taint value the toleration matches to. If the operator is Exists, the value should be empty, otherwise just a regular string. 2.1.268. .spec.topologySpreadConstraints Description If specified, the pod's topology spread constraints. Type array 2.1.269. .spec.topologySpreadConstraints[] Description TopologySpreadConstraint specifies how to spread matching pods among the given topology. Type object Required maxSkew topologyKey whenUnsatisfiable Property Type Description labelSelector object LabelSelector is used to find matching pods. Pods that match this label selector are counted to determine the number of pods in their corresponding topology domain. matchLabelKeys array (string) MatchLabelKeys is a set of pod label keys to select the pods over which spreading will be calculated. The keys are used to lookup values from the incoming pod labels, those key-value labels are ANDed with labelSelector to select the group of existing pods over which spreading will be calculated for the incoming pod. The same key is forbidden to exist in both MatchLabelKeys and LabelSelector. MatchLabelKeys cannot be set when LabelSelector isn't set. Keys that don't exist in the incoming pod labels will be ignored. A null or empty list means only match against labelSelector. This is a beta field and requires the MatchLabelKeysInPodTopologySpread feature gate to be enabled (enabled by default). maxSkew integer MaxSkew describes the degree to which pods may be unevenly distributed. When whenUnsatisfiable=DoNotSchedule , it is the maximum permitted difference between the number of matching pods in the target topology and the global minimum. The global minimum is the minimum number of matching pods in an eligible domain or zero if the number of eligible domains is less than MinDomains. For example, in a 3-zone cluster, MaxSkew is set to 1, and pods with the same labelSelector spread as 2/2/1: In this case, the global minimum is 1. | zone1 | zone2 | zone3 | | P P | P P | P | - if MaxSkew is 1, incoming pod can only be scheduled to zone3 to become 2/2/2; scheduling it onto zone1(zone2) would make the ActualSkew(3-1) on zone1(zone2) violate MaxSkew(1). - if MaxSkew is 2, incoming pod can be scheduled onto any zone. When whenUnsatisfiable=ScheduleAnyway , it is used to give higher precedence to topologies that satisfy it. It's a required field. Default value is 1 and 0 is not allowed. minDomains integer MinDomains indicates a minimum number of eligible domains. When the number of eligible domains with matching topology keys is less than minDomains, Pod Topology Spread treats "global minimum" as 0, and then the calculation of Skew is performed. And when the number of eligible domains with matching topology keys equals or greater than minDomains, this value has no effect on scheduling. As a result, when the number of eligible domains is less than minDomains, scheduler won't schedule more than maxSkew Pods to those domains. If value is nil, the constraint behaves as if MinDomains is equal to 1. Valid values are integers greater than 0. When value is not nil, WhenUnsatisfiable must be DoNotSchedule. For example, in a 3-zone cluster, MaxSkew is set to 2, MinDomains is set to 5 and pods with the same labelSelector spread as 2/2/2: | zone1 | zone2 | zone3 | | P P | P P | P P | The number of domains is less than 5(MinDomains), so "global minimum" is treated as 0. In this situation, new pod with the same labelSelector cannot be scheduled, because computed skew will be 3(3 - 0) if new Pod is scheduled to any of the three zones, it will violate MaxSkew. nodeAffinityPolicy string NodeAffinityPolicy indicates how we will treat Pod's nodeAffinity/nodeSelector when calculating pod topology spread skew. Options are: - Honor: only nodes matching nodeAffinity/nodeSelector are included in the calculations. - Ignore: nodeAffinity/nodeSelector are ignored. All nodes are included in the calculations. If this value is nil, the behavior is equivalent to the Honor policy. This is a beta-level feature default enabled by the NodeInclusionPolicyInPodTopologySpread feature flag. nodeTaintsPolicy string NodeTaintsPolicy indicates how we will treat node taints when calculating pod topology spread skew. Options are: - Honor: nodes without taints, along with tainted nodes for which the incoming pod has a toleration, are included. - Ignore: node taints are ignored. All nodes are included. If this value is nil, the behavior is equivalent to the Ignore policy. This is a beta-level feature default enabled by the NodeInclusionPolicyInPodTopologySpread feature flag. topologyKey string TopologyKey is the key of node labels. Nodes that have a label with this key and identical values are considered to be in the same topology. We consider each <key, value> as a "bucket", and try to put balanced number of pods into each bucket. We define a domain as a particular instance of a topology. Also, we define an eligible domain as a domain whose nodes meet the requirements of nodeAffinityPolicy and nodeTaintsPolicy. e.g. If TopologyKey is "kubernetes.io/hostname", each Node is a domain of that topology. And, if TopologyKey is "topology.kubernetes.io/zone", each zone is a domain of that topology. It's a required field. whenUnsatisfiable string WhenUnsatisfiable indicates how to deal with a pod if it doesn't satisfy the spread constraint. - DoNotSchedule (default) tells the scheduler not to schedule it. - ScheduleAnyway tells the scheduler to schedule the pod in any location, but giving higher precedence to topologies that would help reduce the skew. A constraint is considered "Unsatisfiable" for an incoming pod if and only if every possible node assignment for that pod would violate "MaxSkew" on some topology. For example, in a 3-zone cluster, MaxSkew is set to 1, and pods with the same labelSelector spread as 3/1/1: | zone1 | zone2 | zone3 | | P P P | P | P | If WhenUnsatisfiable is set to DoNotSchedule, incoming pod can only be scheduled to zone2(zone3) to become 3/2/1(3/1/2) as ActualSkew(2-1) on zone2(zone3) satisfies MaxSkew(1). In other words, the cluster can still be imbalanced, but scheduler won't make it more imbalanced. It's a required field. 2.1.270. .spec.topologySpreadConstraints[].labelSelector Description LabelSelector is used to find matching pods. Pods that match this label selector are counted to determine the number of pods in their corresponding topology domain. Type object Property Type Description matchExpressions array matchExpressions is a list of label selector requirements. The requirements are ANDed. matchExpressions[] object A label selector requirement is a selector that contains values, a key, and an operator that relates the key and values. matchLabels object (string) matchLabels is a map of {key,value} pairs. A single {key,value} in the matchLabels map is equivalent to an element of matchExpressions, whose key field is "key", the operator is "In", and the values array contains only "value". The requirements are ANDed. 2.1.271. .spec.topologySpreadConstraints[].labelSelector.matchExpressions Description matchExpressions is a list of label selector requirements. The requirements are ANDed. Type array 2.1.272. .spec.topologySpreadConstraints[].labelSelector.matchExpressions[] Description A label selector requirement is a selector that contains values, a key, and an operator that relates the key and values. Type object Required key operator Property Type Description key string key is the label key that the selector applies to. operator string operator represents a key's relationship to a set of values. Valid operators are In, NotIn, Exists and DoesNotExist. values array (string) values is an array of string values. If the operator is In or NotIn, the values array must be non-empty. If the operator is Exists or DoesNotExist, the values array must be empty. This array is replaced during a strategic merge patch. 2.1.273. .spec.volumeMounts Description VolumeMounts allows configuration of additional VolumeMounts on the output StatefulSet definition. VolumeMounts specified will be appended to other VolumeMounts in the alertmanager container, that are generated as a result of StorageSpec objects. Type array 2.1.274. .spec.volumeMounts[] Description VolumeMount describes a mounting of a Volume within a container. Type object Required mountPath name Property Type Description mountPath string Path within the container at which the volume should be mounted. Must not contain ':'. mountPropagation string mountPropagation determines how mounts are propagated from the host to container and the other way around. When not set, MountPropagationNone is used. This field is beta in 1.10. When RecursiveReadOnly is set to IfPossible or to Enabled, MountPropagation must be None or unspecified (which defaults to None). name string This must match the Name of a Volume. readOnly boolean Mounted read-only if true, read-write otherwise (false or unspecified). Defaults to false. recursiveReadOnly string RecursiveReadOnly specifies whether read-only mounts should be handled recursively. If ReadOnly is false, this field has no meaning and must be unspecified. If ReadOnly is true, and this field is set to Disabled, the mount is not made recursively read-only. If this field is set to IfPossible, the mount is made recursively read-only, if it is supported by the container runtime. If this field is set to Enabled, the mount is made recursively read-only if it is supported by the container runtime, otherwise the pod will not be started and an error will be generated to indicate the reason. If this field is set to IfPossible or Enabled, MountPropagation must be set to None (or be unspecified, which defaults to None). If this field is not specified, it is treated as an equivalent of Disabled. subPath string Path within the volume from which the container's volume should be mounted. Defaults to "" (volume's root). subPathExpr string Expanded path within the volume from which the container's volume should be mounted. Behaves similarly to SubPath but environment variable references USD(VAR_NAME) are expanded using the container's environment. Defaults to "" (volume's root). SubPathExpr and SubPath are mutually exclusive. 2.1.275. .spec.volumes Description Volumes allows configuration of additional volumes on the output StatefulSet definition. Volumes specified will be appended to other volumes that are generated as a result of StorageSpec objects. Type array 2.1.276. .spec.volumes[] Description Volume represents a named volume in a pod that may be accessed by any container in the pod. Type object Required name Property Type Description awsElasticBlockStore object awsElasticBlockStore represents an AWS Disk resource that is attached to a kubelet's host machine and then exposed to the pod. More info: https://kubernetes.io/docs/concepts/storage/volumes#awselasticblockstore azureDisk object azureDisk represents an Azure Data Disk mount on the host and bind mount to the pod. azureFile object azureFile represents an Azure File Service mount on the host and bind mount to the pod. cephfs object cephFS represents a Ceph FS mount on the host that shares a pod's lifetime cinder object cinder represents a cinder volume attached and mounted on kubelets host machine. More info: https://examples.k8s.io/mysql-cinder-pd/README.md configMap object configMap represents a configMap that should populate this volume csi object csi (Container Storage Interface) represents ephemeral storage that is handled by certain external CSI drivers (Beta feature). downwardAPI object downwardAPI represents downward API about the pod that should populate this volume emptyDir object emptyDir represents a temporary directory that shares a pod's lifetime. More info: https://kubernetes.io/docs/concepts/storage/volumes#emptydir ephemeral object ephemeral represents a volume that is handled by a cluster storage driver. The volume's lifecycle is tied to the pod that defines it - it will be created before the pod starts, and deleted when the pod is removed. Use this if: a) the volume is only needed while the pod runs, b) features of normal volumes like restoring from snapshot or capacity tracking are needed, c) the storage driver is specified through a storage class, and d) the storage driver supports dynamic volume provisioning through a PersistentVolumeClaim (see EphemeralVolumeSource for more information on the connection between this volume type and PersistentVolumeClaim).

The default is nil which means that the limit is undefined. More info: https://kubernetes.io/docs/concepts/storage/volumes#emptydir 2.1.295. .spec.volumes[].ephemeral Description ephemeral represents a volume that is handled by a cluster storage driver. The volume's lifecycle is tied to the pod that defines it - it will be created before the pod starts, and deleted when the pod is removed. Use this if: a) the volume is only needed while the pod runs, b) features of normal volumes like restoring from snapshot or capacity tracking are needed, c) the storage driver is specified through a storage class, and d) the storage driver supports dynamic volume provisioning through a PersistentVolumeClaim (see EphemeralVolumeSource for more information on the connection between this volume type and PersistentVolumeClaim). Use PersistentVolumeClaim or one of the vendor-specific APIs for volumes that persist for longer than the lifecycle of an individual pod. Use CSI for light-weight local ephemeral volumes if the CSI driver is meant to be used that way - see the documentation of the driver for more information. A pod can use both types of ephemeral volumes and persistent volumes at the same time. Type object Property Type Description volumeClaimTemplate object Will be used to create a stand-alone PVC to provision the volume. The pod in which this EphemeralVolumeSource is embedded will be the owner of the PVC, i.e. the PVC will be deleted together with the pod. The name of the PVC will be <pod name>-<volume name> where <volume name> is the name from the PodSpec.Volumes array entry. Pod validation will reject the pod if the concatenated name is not valid for a PVC (for example, too long). An existing PVC with that name that is not owned by the pod will not be used for the pod to avoid using an unrelated volume by mistake. Starting the pod is then blocked until the unrelated PVC is removed. If such a pre-created PVC is meant to be used by the pod, the PVC has to updated with an owner reference to the pod once the pod exists. Normally this should not be necessary, but it may be useful when manually reconstructing a broken cluster. This field is read-only and no changes will be made by Kubernetes to the PVC after it has been created. Required, must not be nil. 2.1.296. .spec.volumes[].ephemeral.volumeClaimTemplate Description Will be used to create a stand-alone PVC to provision the volume. The pod in which this EphemeralVolumeSource is embedded will be the owner of the PVC, i.e. the PVC will be deleted together with the pod. The name of the PVC will be <pod name>-<volume name> where <volume name> is the name from the PodSpec.Volumes array entry. Pod validation will reject the pod if the concatenated name is not valid for a PVC (for example, too long). An existing PVC with that name that is not owned by the pod will not be used for the pod to avoid using an unrelated volume by mistake. Starting the pod is then blocked until the unrelated PVC is removed. If such a pre-created PVC is meant to be used by the pod, the PVC has to updated with an owner reference to the pod once the pod exists. Normally this should not be necessary, but it may be useful when manually reconstructing a broken cluster. This field is read-only and no changes will be made by Kubernetes to the PVC after it has been created. Required, must not be nil. Type object Required spec Property Type Description metadata object May contain labels and annotations that will be copied into the PVC when creating it. No other fields are allowed and will be rejected during validation. spec object The specification for the PersistentVolumeClaim. The entire content is copied unchanged into the PVC that gets created from this template. The same fields as in a PersistentVolumeClaim are also valid here. 2.1.297. .spec.volumes[].ephemeral.volumeClaimTemplate.metadata Description May contain labels and annotations that will be copied into the PVC when creating it. No other fields are allowed and will be rejected during validation. Type object 2.1.298. .spec.volumes[].ephemeral.volumeClaimTemplate.spec Description The specification for the PersistentVolumeClaim. The entire content is copied unchanged into the PVC that gets created from this template. The same fields as in a PersistentVolumeClaim are also valid here. Type object Property Type Description accessModes array (string) accessModes contains the desired access modes the volume should have. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#access-modes-1 dataSource object dataSource field can be used to specify either: * An existing VolumeSnapshot object (snapshot.storage.k8s.io/VolumeSnapshot) * An existing PVC (PersistentVolumeClaim) If the provisioner or an external controller can support the specified data source, it will create a new volume based on the contents of the specified data source. When the AnyVolumeDataSource feature gate is enabled, dataSource contents will be copied to dataSourceRef, and dataSourceRef contents will be copied to dataSource when dataSourceRef.namespace is not specified. If the namespace is specified, then dataSourceRef will not be copied to dataSource. dataSourceRef object dataSourceRef specifies the object from which to populate the volume with data, if a non-empty volume is desired. This may be any object from a non-empty API group (non core object) or a PersistentVolumeClaim object. When this field is specified, volume binding will only succeed if the type of the specified object matches some installed volume populator or dynamic provisioner. This field will replace the functionality of the dataSource field and as such if both fields are non-empty, they must have the same value. For backwards compatibility, when namespace isn't specified in dataSourceRef, both fields (dataSource and dataSourceRef) will be set to the same value automatically if one of them is empty and the other is non-empty. When namespace is specified in dataSourceRef, dataSource isn't set to the same value and must be empty. There are three important differences between dataSource and dataSourceRef: * While dataSource only allows two specific types of objects, dataSourceRef allows any non-core object, as well as PersistentVolumeClaim objects. * While dataSource ignores disallowed values (dropping them), dataSourceRef preserves all values, and generates an error if a disallowed value is specified. * While dataSource only allows local objects, dataSourceRef allows objects in any namespaces. (Beta) Using this field requires the AnyVolumeDataSource feature gate to be enabled. (Alpha) Using the namespace field of dataSourceRef requires the CrossNamespaceVolumeDataSource feature gate to be enabled. resources object resources represents the minimum resources the volume should have. If RecoverVolumeExpansionFailure feature is enabled users are allowed to specify resource requirements that are lower than value but must still be higher than capacity recorded in the status field of the claim. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#resources selector object selector is a label query over volumes to consider for binding. storageClassName string storageClassName is the name of the StorageClass required by the claim. More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes#class-1 volumeAttributesClassName string volumeAttributesClassName may be used to set the VolumeAttributesClass used by this claim. If specified, the CSI driver will create or update the volume with the attributes defined in the corresponding VolumeAttributesClass. This has a different purpose than storageClassName, it can be changed after the claim is created. An empty string value means that no VolumeAttributesClass will be applied to the claim but it's not allowed to reset this field to empty string once it is set. If unspecified and the PersistentVolumeClaim is unbound, the default VolumeAttributesClass will be set by the persistentvolume controller if it exists. If the resource referred to by volumeAttributesClass does not exist, this PersistentVolumeClaim will be set to a Pending state, as reflected by the modifyVolumeStatus field, until such as a resource exists. More info: https://kubernetes.io/docs/concepts/storage/volume-attributes-classes/ (Alpha) Using this field requires the VolumeAttributesClass feature gate to be enabled. volumeMode string volumeMode defines what type of volume is required by the claim. Value of Filesystem is implied when not included in claim spec. volumeName string volumeName is the binding reference to the PersistentVolume backing this claim. 2.1.299. .spec.volumes[].ephemeral.volumeClaimTemplate.spec.dataSource Description dataSource field can be used to specify either: * An existing VolumeSnapshot object (snapshot.storage.k8s.io/VolumeSnapshot) * An existing PVC (PersistentVolumeClaim) If the provisioner or an external controller can support the specified data source, it will create a new volume based on the contents of the specified data source. When the AnyVolumeDataSource feature gate is enabled, dataSource contents will be copied to dataSourceRef, and dataSourceRef contents will be copied to dataSource when dataSourceRef.namespace is not specified. If the namespace is specified, then dataSourceRef will not be copied to dataSource.

When this field is specified, volume binding will only succeed if the type of the specified object matches some installed volume populator or dynamic provisioner. This field will replace the functionality of the dataSource field and as such if both fields are non-empty, they must have the same value.

If APIGroup is not specified, the specified Kind must be in the core API group. For any other third-party types, APIGroup is required. kind string Kind is the type of resource being referenced name string Name is the name of resource being referenced namespace string Namespace is the namespace of resource being referenced Note that when a namespace is specified, a gateway.networking.k8s.io/ReferenceGrant object is required in the referent namespace to allow that namespace's owner to accept the reference. See the ReferenceGrant documentation for details. (Alpha) This field requires the CrossNamespaceVolumeDataSource feature gate to be enabled. 2.1.301. .spec.volumes[].ephemeral.volumeClaimTemplate.spec.resources Description resources represents the minimum resources the volume should have.
