Chapter 15. ReplicationController [v1] Description ReplicationController represents the configuration of a replication controller. Type object 15.1. 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 If the Labels of a ReplicationController are empty, they are defaulted to be the same as the Pod(s) that the replication controller manages. Standard object's metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata spec object ReplicationControllerSpec is the specification of a replication controller. status object ReplicationControllerStatus represents the current status of a replication controller. 15.1.1. .spec Description ReplicationControllerSpec is the specification of a replication controller. Type object Property Type Description 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) replicas integer Replicas is the number of desired replicas. This is a pointer to distinguish between explicit zero and unspecified. Defaults to 1. More info: https://kubernetes.io/docs/concepts/workloads/controllers/replicationcontroller#what-is-a-replicationcontroller selector object (string) Selector is a label query over pods that should match the Replicas count. If Selector is empty, it is defaulted to the labels present on the Pod template. Label keys and values that must match in order to be controlled by this replication controller, if empty defaulted to labels on Pod template. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/#label-selectors template object PodTemplateSpec describes the data a pod should have when created from a template 15.1.2. .spec.template Description PodTemplateSpec describes the data a pod should have when created from a template Type object Property Type Description metadata ObjectMeta Standard object's metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata spec object PodSpec is a description of a pod. 15.1.3. .spec.template.spec Description PodSpec is a description of a pod. Type object Required containers Property Type Description activeDeadlineSeconds integer Optional duration in seconds the pod may be active on the node relative to StartTime before the system will actively try to mark it failed and kill associated containers. Value must be a positive integer. affinity object Affinity is a group of affinity scheduling rules. automountServiceAccountToken boolean AutomountServiceAccountToken indicates whether a service account token should be automatically mounted. containers array List of containers belonging to the pod. Containers cannot currently be added or removed. There must be at least one container in a Pod. Cannot be updated. containers[] object A single application container that you want to run within a pod. dnsConfig object PodDNSConfig defines the DNS parameters of a pod in addition to those generated from DNSPolicy. dnsPolicy string Set DNS policy for the pod. Defaults to "ClusterFirst". Valid values are 'ClusterFirstWithHostNet', 'ClusterFirst', 'Default' or 'None'. DNS parameters given in DNSConfig will be merged with the policy selected with DNSPolicy. To have DNS options set along with hostNetwork, you have to specify DNS policy explicitly to 'ClusterFirstWithHostNet'. Possible enum values: - "ClusterFirst" indicates that the pod should use cluster DNS first unless hostNetwork is true, if it is available, then fall back on the default (as determined by kubelet) DNS settings. - "ClusterFirstWithHostNet" indicates that the pod should use cluster DNS first, if it is available, then fall back on the default (as determined by kubelet) DNS settings. - "Default" indicates that the pod should use the default (as determined by kubelet) DNS settings. - "None" indicates that the pod should use empty DNS settings. DNS parameters such as nameservers and search paths should be defined via DNSConfig. enableServiceLinks boolean EnableServiceLinks indicates whether information about services should be injected into pod's environment variables, matching the syntax of Docker links. Optional: Defaults to true. ephemeralContainers array List of ephemeral containers run in this pod. Ephemeral containers may be run in an existing pod to perform user-initiated actions such as debugging. This list cannot be specified when creating a pod, and it cannot be modified by updating the pod spec. In order to add an ephemeral container to an existing pod, use the pod's ephemeralcontainers subresource. ephemeralContainers[] object An EphemeralContainer is a temporary container that you may add to an existing Pod for user-initiated activities such as debugging. Ephemeral containers have no resource or scheduling guarantees, and they will not be restarted when they exit or when a Pod is removed or restarted. The kubelet may evict a Pod if an ephemeral container causes the Pod to exceed its resource allocation. To add an ephemeral container, use the ephemeralcontainers subresource of an existing Pod. Ephemeral containers may not be removed or restarted. hostAliases array HostAliases is an optional list of hosts and IPs that will be injected into the pod's hosts file if specified. This is only valid for non-hostNetwork pods. hostAliases[] object HostAlias holds the mapping between IP and hostnames that will be injected as an entry in the pod's hosts file. hostIPC boolean Use the host's ipc namespace. Optional: Default to false. hostNetwork boolean Host networking requested for this pod. Use the host's network namespace. If this option is set, the ports that will be used must be specified. Default to false. hostPID boolean Use the host's pid namespace. Optional: Default to false. hostUsers boolean Use the host's user namespace. Optional: Default to true. If set to true or not present, the pod will be run in the host user namespace, useful for when the pod needs a feature only available to the host user namespace, such as loading a kernel module with CAP_SYS_MODULE. When set to false, a new userns is created for the pod. Setting false is useful for mitigating container breakout vulnerabilities even allowing users to run their containers as root without actually having root privileges on the host. This field is alpha-level and is only honored by servers that enable the UserNamespacesSupport feature. hostname string Specifies the hostname of the Pod If not specified, the pod's hostname will be set to a system-defined value. imagePullSecrets array ImagePullSecrets is an optional list of references to secrets in the same namespace to use for pulling any of the images used by this PodSpec. If specified, these secrets will be passed to individual puller implementations for them to use. More info: https://kubernetes.io/docs/concepts/containers/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 List of initialization containers belonging to the pod. Init containers are executed in order prior to containers being started. If any init container fails, the pod is considered to have failed and is handled according to its restartPolicy. The name for an init container or normal container must be unique among all containers. Init containers may not have Lifecycle actions, Readiness probes, Liveness probes, or Startup probes. The resourceRequirements of an init container are taken into account during scheduling by finding the highest request/limit for each resource type, and then using the max of of that value or the sum of the normal containers. Limits are applied to init containers in a similar fashion. Init containers cannot currently be added or removed. Cannot be updated. More info: https://kubernetes.io/docs/concepts/workloads/pods/init-containers/ initContainers[] object A single application container that you want to run within a pod. nodeName string NodeName is a request to schedule this pod onto a specific node. If it is non-empty, the scheduler simply schedules this pod onto that node, assuming that it fits resource requirements. nodeSelector object (string) NodeSelector is a selector which must be true for the pod to fit on a node. Selector which must match a node's labels for the pod to be scheduled on that node. More info: https://kubernetes.io/docs/concepts/configuration/assign-pod-node/ os object PodOS defines the OS parameters of a pod. overhead object (Quantity) Overhead represents the resource overhead associated with running a pod for a given RuntimeClass. This field will be autopopulated at admission time by the RuntimeClass admission controller. If the RuntimeClass admission controller is enabled, overhead must not be set in Pod create requests. The RuntimeClass admission controller will reject Pod create requests which have the overhead already set. If RuntimeClass is configured and selected in the PodSpec, Overhead will be set to the value defined in the corresponding RuntimeClass, otherwise it will remain unset and treated as zero. More info: https://git.k8s.io/enhancements/keps/sig-node/688-pod-overhead/README.md preemptionPolicy string PreemptionPolicy is the Policy for preempting pods with lower priority. One of Never, PreemptLowerPriority. Defaults to PreemptLowerPriority if unset. Possible enum values: - "Never" means that pod never preempts other pods with lower priority. - "PreemptLowerPriority" means that pod can preempt other pods with lower priority. priority integer The priority value. Various system components use this field to find the priority of the pod. When Priority Admission Controller is enabled, it prevents users from setting this field. The admission controller populates this field from PriorityClassName. The higher the value, the higher the priority. priorityClassName string If specified, indicates the pod's priority. "system-node-critical" and "system-cluster-critical" are two special keywords which indicate the highest priorities with the former being the highest priority. Any other name must be defined by creating a PriorityClass object with that name. If not specified, the pod priority will be default or zero if there is no default. readinessGates array If specified, all readiness gates will be evaluated for pod readiness. A pod is ready when all its containers are ready AND all conditions specified in the readiness gates have status equal to "True" More info: https://git.k8s.io/enhancements/keps/sig-network/580-pod-readiness-gates readinessGates[] object PodReadinessGate contains the reference to a pod condition resourceClaims array ResourceClaims defines which ResourceClaims must be allocated and reserved before the Pod is allowed to start. The resources will be made available to those containers which consume them by name. This is an alpha field and requires enabling the DynamicResourceAllocation feature gate. This field is immutable. resourceClaims[] object PodResourceClaim references exactly one ResourceClaim through a ClaimSource. It adds a name to it that uniquely identifies the ResourceClaim inside the Pod. Containers that need access to the ResourceClaim reference it with this name. restartPolicy string Restart policy for all containers within the pod. One of Always, OnFailure, Never. In some contexts, only a subset of those values may be permitted. Default to Always. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle/#restart-policy Possible enum values: - "Always" - "Never" - "OnFailure" runtimeClassName string RuntimeClassName refers to a RuntimeClass object in the node.k8s.io group, which should be used to run this pod. If no RuntimeClass resource matches the named class, the pod will not be run. If unset or empty, the "legacy" RuntimeClass will be used, which is an implicit class with an empty definition that uses the default runtime handler. More info: https://git.k8s.io/enhancements/keps/sig-node/585-runtime-class schedulerName string If specified, the pod will be dispatched by specified scheduler. If not specified, the pod will be dispatched by default scheduler. schedulingGates array SchedulingGates is an opaque list of values that if specified will block scheduling the pod. If schedulingGates is not empty, the pod will stay in the SchedulingGated state and the scheduler will not attempt to schedule the pod. SchedulingGates can only be set at pod creation time, and be removed only afterwards. This is a beta feature enabled by the PodSchedulingReadiness feature gate. schedulingGates[] object PodSchedulingGate is associated to a Pod to guard its scheduling. securityContext object PodSecurityContext holds pod-level security attributes and common container settings. Some fields are also present in container.securityContext. Field values of container.securityContext take precedence over field values of PodSecurityContext. serviceAccount string DeprecatedServiceAccount is a depreciated alias for ServiceAccountName. Deprecated: Use serviceAccountName instead. serviceAccountName string ServiceAccountName is the name of the ServiceAccount to use to run this pod. More info: https://kubernetes.io/docs/tasks/configure-pod-container/configure-service-account/ setHostnameAsFQDN boolean If true the pod's hostname will be configured as the pod's FQDN, rather than the leaf name (the default). In Linux containers, this means setting the FQDN in the hostname field of the kernel (the nodename field of struct utsname). In Windows containers, this means setting the registry value of hostname for the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters to FQDN. If a pod does not have FQDN, this has no effect. Default to false. shareProcessNamespace boolean Share a single process namespace between all of the containers in a pod. When this is set containers will be able to view and signal processes from other containers in the same pod, and the first process in each container will not be assigned PID 1. HostPID and ShareProcessNamespace cannot both be set. Optional: Default to false. subdomain string If specified, the fully qualified Pod hostname will be "<hostname>.<subdomain>.<pod namespace>.svc.<cluster domain>". If not specified, the pod will not have a domainname at all. terminationGracePeriodSeconds integer Optional duration in seconds the pod needs to terminate gracefully. May be decreased in delete request. Value must be non-negative integer. The value zero indicates stop immediately via the kill signal (no opportunity to shut down). If this value is nil, the default grace period will be used instead. The grace period is the duration in seconds after the processes running in the pod are sent a termination signal and the time when the processes are forcibly halted with a kill signal. Set this value longer than the expected cleanup time for your process. Defaults to 30 seconds. 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 TopologySpreadConstraints describes how a group of pods ought to spread across topology domains. Scheduler will schedule pods in a way which abides by the constraints. All topologySpreadConstraints are ANDed. topologySpreadConstraints[] object TopologySpreadConstraint specifies how to spread matching pods among the given topology. volumes array List of volumes that can be mounted by containers belonging to the 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 Possible enum values: - "Always" means that kubelet always attempts to pull the latest image. Container will fail If the pull fails. - "IfNotPresent" means that kubelet pulls if the image isn't present on disk. Container will fail if the image isn't present and the pull fails. - "Never" means that kubelet never pulls an image, but only uses a local image. Container will fail if the image isn't present lifecycle object Lifecycle describes actions that the management system should take in response to container lifecycle events. For the PostStart and PreStop lifecycle handlers, management of the container blocks until the action is complete, unless the container process fails, in which case the handler is aborted. livenessProbe object Probe describes a health check to be performed against a container to determine whether it is alive or ready to receive traffic. 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 Probe describes a health check to be performed against a container to determine whether it is alive or ready to receive traffic. resizePolicy array Resources resize policy for the container. resizePolicy[] object ContainerResizePolicy represents resource resize policy for the container. resources object ResourceRequirements describes the compute resource requirements. 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 holds security configuration that will be applied to a container. Some fields are present in both SecurityContext and PodSecurityContext. When both are set, the values in SecurityContext take precedence. startupProbe object Probe describes a health check to be performed against a container to determine whether it is alive or ready to receive traffic. 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. Possible enum values: - "FallbackToLogsOnError" will read the most recent contents of the container logs for the container status message when the container exits with an error and the terminationMessagePath has no contents. - "File" is the default behavior and will set the container status message to the contents of the container's terminationMessagePath when the container exits. 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.

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 EnvVarSource represents a source for the value of an EnvVar. 15.1.36. .spec.template.spec.containers[].env[].valueFrom Description EnvVarSource represents a source for the value of an EnvVar.

This field is beta in 1.10. Possible enum values: - "Bidirectional" means that the volume in a container will receive new mounts from the host or other containers, and its own mounts will be propagated from the container to the host or other containers. Note that this mode is recursively applied to all mounts in the volume ("rshared" in Linux terminology). - "HostToContainer" means that the volume in a container will receive new mounts from the host or other containers, but filesystems mounted inside the container won't be propagated to the host or other containers.

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 targetContainerName string If set, the name of the container from PodSpec that this ephemeral container targets. The ephemeral container will be run in the namespaces (IPC, PID, etc) of this container. If not set then the ephemeral container uses the namespaces configured in the Pod spec. The container runtime must implement support for this feature. If the runtime does not support namespace targeting then the result of setting this field is undefined. 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.

The resourceRequirements of an init container are taken into account during scheduling by finding the highest request/limit for each resource type, and then using the max of of that value or the sum of the normal containers. Limits are applied to init containers in a similar fashion. Init containers cannot currently be added or removed. Cannot be updated. More info: https://kubernetes.io/docs/concepts/workloads/pods/init-containers/ Type array 15.1.166. .spec.template.spec.initContainers[] 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 Possible enum values: - "Always" means that kubelet always attempts to pull the latest image. Container will fail If the pull fails. - "IfNotPresent" means that kubelet pulls if the image isn't present on disk. Container will fail if the image isn't present and the pull fails. - "Never" means that kubelet never pulls an image, but only uses a local image. Container will fail if the image isn't present lifecycle object Lifecycle describes actions that the management system should take in response to container lifecycle events. For the PostStart and PreStop lifecycle handlers, management of the container blocks until the action is complete, unless the container process fails, in which case the handler is aborted. livenessProbe object Probe describes a health check to be performed against a container to determine whether it is alive or ready to receive traffic. 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 Probe describes a health check to be performed against a container to determine whether it is alive or ready to receive traffic. resizePolicy array Resources resize policy for the container. resizePolicy[] object ContainerResizePolicy represents resource resize policy for the container. resources object ResourceRequirements describes the compute resource requirements. 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 holds security configuration that will be applied to a container. Some fields are present in both SecurityContext and PodSecurityContext. When both are set, the values in SecurityContext take precedence. startupProbe object Probe describes a health check to be performed against a container to determine whether it is alive or ready to receive traffic. 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. Possible enum values: - "FallbackToLogsOnError" will read the most recent contents of the container logs for the container status message when the container exits with an error and the terminationMessagePath has no contents. - "File" is the default behavior and will set the container status message to the contents of the container's terminationMessagePath when the container exits. 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. 15.1.167. .spec.template.spec.initContainers[].env Description List of environment variables to set in the container. Cannot be updated. Type array 15.1.168. .spec.template.spec.initContainers[].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 EnvVarSource represents a source for the value of an EnvVar. 15.1.169. .spec.template.spec.initContainers[].env[].valueFrom Description EnvVarSource represents a source for the value of an EnvVar.

Type object Property Type Description allowPrivilegeEscalation boolean AllowPrivilegeEscalation controls whether a process can gain more privileges than its parent process. This bool directly controls if the no_new_privs flag will be set on the container process. AllowPrivilegeEscalation is true always when the container is: 1) run as Privileged 2) has CAP_SYS_ADMIN Note that this field cannot be set when spec.os.name is windows. capabilities object Adds and removes POSIX capabilities from running containers. privileged boolean Run container in privileged mode. Processes in privileged containers are essentially equivalent to root on the host. Defaults to false. Note that this field cannot be set when spec.os.name is windows. procMount string procMount denotes the type of proc mount to use for the containers. The default is DefaultProcMount which uses the container runtime defaults for readonly paths and masked paths. This requires the ProcMountType feature flag to be enabled. Note that this field cannot be set when spec.os.name is windows. Possible enum values: - "Default" uses the container runtime defaults for readonly and masked paths for /proc. Most container runtimes mask certain paths in /proc to avoid accidental security exposure of special devices or information. - "Unmasked" bypasses the default masking behavior of the container runtime and ensures the newly created /proc the container stays in tact with no modifications. readOnlyRootFilesystem boolean Whether this container has a read-only root filesystem. Default is false. Note that this field cannot be set when spec.os.name is windows. runAsGroup integer The GID to run the entrypoint of the container process. Uses runtime default if unset. May also be set in PodSecurityContext. If set in both SecurityContext and PodSecurityContext, the value specified in SecurityContext takes precedence. Note that this field cannot be set when spec.os.name is windows. runAsNonRoot boolean Indicates that the container must run as a non-root user. 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 PodSecurityContext. 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. Defaults to user specified in image metadata if unspecified. May also be set in PodSecurityContext. If set in both SecurityContext and PodSecurityContext, the value specified in SecurityContext takes precedence. Note that this field cannot be set when spec.os.name is windows. seLinuxOptions object SELinuxOptions are the labels to be applied to the container seccompProfile object SeccompProfile defines a pod/container's seccomp profile settings.

Must NOT be set for any other type. type string type indicates which kind of seccomp profile will be applied. Valid options are: Localhost - a profile defined in a file on the node should be used. RuntimeDefault - the container runtime default profile should be used. Unconfined - no profile should be applied. Possible enum values: - "Localhost" indicates a profile defined in a file on the node should be used. The file's location relative to <kubelet-root-dir>/seccomp. - "RuntimeDefault" represents the default container runtime seccomp profile. - "Unconfined" indicates no seccomp profile is applied (A.K.A. unconfined). 15.1.216. .spec.template.spec.initContainers[].securityContext.windowsOptions Description WindowsSecurityContextOptions contain Windows-specific options and credentials. Type object Property Type Description gmsaCredentialSpec string GMSACredentialSpec is where the GMSA admission webhook ( https://github.com/kubernetes-sigs/windows-gmsa ) inlines the contents of the GMSA credential spec named by the GMSACredentialSpecName field. gmsaCredentialSpecName string GMSACredentialSpecName is the name of the GMSA credential spec to use. hostProcess boolean HostProcess determines if a container should be run as a 'Host Process' container. All of a Pod's containers must have the same effective HostProcess value (it is not allowed to have a mix of HostProcess containers and non-HostProcess containers). In addition, if HostProcess is true then HostNetwork must also be set to true. runAsUserName string The UserName in Windows to run the entrypoint of the container process. Defaults to the user specified in image metadata if unspecified. May also be set in PodSecurityContext. If set in both SecurityContext and PodSecurityContext, the value specified in SecurityContext takes precedence. 15.1.217. .spec.template.spec.initContainers[].startupProbe Description Probe describes a health check to be performed against a container to determine whether it is alive or ready to receive traffic.

The grace period is the duration in seconds after the processes running in the pod are sent a termination signal and the time when the processes are forcibly halted with a kill signal. Set this value longer than the expected cleanup time for your process. If this value is nil, the pod's terminationGracePeriodSeconds will be used. Otherwise, this value overrides the value provided by the pod spec. Value must be non-negative integer. The value zero indicates stop immediately via the kill signal (no opportunity to shut down). This is a beta field and requires enabling ProbeTerminationGracePeriod feature gate. Minimum value is 1. spec.terminationGracePeriodSeconds is used if unset. timeoutSeconds integer Number of seconds after which the probe times out. Defaults to 1 second. Minimum value is 1. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes 15.1.218. .spec.template.spec.initContainers[].startupProbe.exec Description ExecAction describes a "run in container" action. Type object Property Type Description command array (string) Command is the command line to execute inside the container, the working directory for the command is root ('/') in the container's filesystem. The command is simply exec'd, it is not run inside a shell, so traditional shell instructions ('|', etc) won't work. To use a shell, you need to explicitly call out to that shell. Exit status of 0 is treated as live/healthy and non-zero is unhealthy. 15.1.219. .spec.template.spec.initContainers[].startupProbe.grpc Description GRPC specifies an action involving a GRPC port. Type object Required port Property Type Description port integer Port number of the gRPC service.

You probably want to set "Host" in httpHeaders instead. httpHeaders array Custom headers to set in the request. HTTP allows repeated headers. httpHeaders[] object HTTPHeader describes a custom header to be used in HTTP probes path string Path to access on the HTTP server. port IntOrString Name or number of the port to access on the container. Number must be in the range 1 to 65535. Name must be an IANA_SVC_NAME. scheme string Scheme to use for connecting to the host. Defaults to HTTP. Possible enum values: - "HTTP" means that the scheme used will be http:// - "HTTPS" means that the scheme used will be https:// 15.1.221. .spec.template.spec.initContainers[].startupProbe.httpGet.httpHeaders Description Custom headers to set in the request. HTTP allows repeated headers. Type array 15.1.222. .spec.template.spec.initContainers[].startupProbe.httpGet.httpHeaders[] Description HTTPHeader describes a custom header to be used in HTTP probes Type object Required name value Property Type Description name string The header field name. This will be canonicalized upon output, so case-variant names will be understood as the same header. value string The header field value 15.1.223. .spec.template.spec.initContainers[].startupProbe.tcpSocket Description TCPSocketAction describes an action based on opening a socket Type object Required port Property Type Description host string Optional: Host name to connect to, defaults to the pod IP. port IntOrString Number or name of the port to access on the container.

Cannot be updated. Type array 15.1.227. .spec.template.spec.initContainers[].volumeMounts[] Description VolumeMount describes a mounting of a Volume within a container. Type object Required name mountPath 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. Possible enum values: - "Bidirectional" means that the volume in a container will receive new mounts from the host or other containers, and its own mounts will be propagated from the container to the host or other containers. Note that this mode is recursively applied to all mounts in the volume ("rshared" in Linux terminology). - "HostToContainer" means that the volume in a container will receive new mounts from the host or other containers, but filesystems mounted inside the container won't be propagated to the host or other containers. Note that this mode is recursively applied to all mounts in the volume ("rslave" in Linux terminology). - "None" means that the volume in a container will not receive new mounts from the host or other containers, and filesystems mounted inside the container won't be propagated to the host or other containers. Note that this mode corresponds to "private" in Linux terminology. 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. 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. 15.1.228. .spec.template.spec.os Description PodOS defines the OS parameters of a pod. Type object Required name Property Type Description name string Name is the name of the operating system. The currently supported values are linux and windows. Additional value may be defined in future and can be one of: https://github.com/opencontainers/runtime-spec/blob/master/config.md#platform-specific-configuration Clients should expect to handle additional values and treat unrecognized values in this field as os: null 15.1.229. .spec.template.spec.readinessGates Description If specified, all readiness gates will be evaluated for pod readiness. A pod is ready when all its containers are ready AND all conditions specified in the readiness gates have status equal to "True" More info: https://git.k8s.io/enhancements/keps/sig-network/580-pod-readiness-gates Type array 15.1.230. .spec.template.spec.readinessGates[] Description PodReadinessGate contains the reference to a pod condition Type object Required conditionType Property Type Description conditionType string ConditionType refers to a condition in the pod's condition list with matching type. 15.1.231. .spec.template.spec.resourceClaims Description ResourceClaims defines which ResourceClaims must be allocated and reserved before the Pod is allowed to start. The resources will be made available to those containers which consume them by name. This is an alpha field and requires enabling the DynamicResourceAllocation feature gate. This field is immutable. Type array 15.1.232. .spec.template.spec.resourceClaims[] Description PodResourceClaim references exactly one ResourceClaim through a ClaimSource. It adds a name to it that uniquely identifies the ResourceClaim inside the Pod. Containers that need access to the ResourceClaim reference it with this name. Type object Required name Property Type Description name string Name uniquely identifies this resource claim inside the pod. This must be a DNS_LABEL. source object ClaimSource describes a reference to a ResourceClaim. Exactly one of these fields should be set. Consumers of this type must treat an empty object as if it has an unknown value. 15.1.233. .spec.template.spec.resourceClaims[].source Description ClaimSource describes a reference to a ResourceClaim. Exactly one of these fields should be set. Consumers of this type must treat an empty object as if it has an unknown value. Type object Property Type Description resourceClaimName string ResourceClaimName is the name of a ResourceClaim object in the same namespace as this pod. resourceClaimTemplateName string ResourceClaimTemplateName is the name of a ResourceClaimTemplate object in the same namespace as this pod. The template will be used to create a new ResourceClaim, which will be bound to this pod. When this pod is deleted, the ResourceClaim will also be deleted. The pod name and resource name, along with a generated component, will be used to form a unique name for the ResourceClaim, which will be recorded in pod.status.resourceClaimStatuses. This field is immutable and no changes will be made to the corresponding ResourceClaim by the control plane after creating the ResourceClaim. 15.1.234. .spec.template.spec.schedulingGates Description SchedulingGates is an opaque list of values that if specified will block scheduling the pod. If schedulingGates is not empty, the pod will stay in the SchedulingGated state and the scheduler will not attempt to schedule the pod. SchedulingGates can only be set at pod creation time, and be removed only afterwards. This is a beta feature enabled by the PodSchedulingReadiness feature gate. Type array 15.1.235. .spec.template.spec.schedulingGates[] Description PodSchedulingGate is associated to a Pod to guard its scheduling. Type object Required name Property Type Description name string Name of the scheduling gate. Each scheduling gate must have a unique name field. 15.1.236. .spec.template.spec.securityContext Description PodSecurityContext holds pod-level security attributes and common container settings. Some fields are also present in container.securityContext. Field values of container.securityContext take precedence over field values of PodSecurityContext. Type object Property Type Description fsGroup integer A special supplemental group that applies to all containers in a pod. Some volume types allow the Kubelet to change the ownership of that volume to be owned by the pod: 1. The owning GID will be the FSGroup 2. The setgid bit is set (new files created in the volume will be owned by FSGroup) 3. The permission bits are OR'd with rw-rw---- If unset, the Kubelet will not modify the ownership and permissions of any volume. Note that this field cannot be set when spec.os.name is windows. fsGroupChangePolicy string fsGroupChangePolicy defines behavior of changing ownership and permission of the volume before being exposed inside Pod. This field will only apply to volume types which support fsGroup based ownership(and permissions). It will have no effect on ephemeral volume types such as: secret, configmaps and emptydir. Valid values are "OnRootMismatch" and "Always". If not specified, "Always" is used. Note that this field cannot be set when spec.os.name is windows. Possible enum values: - "Always" indicates that volume's ownership and permissions should always be changed whenever volume is mounted inside a Pod. This the default behavior. - "OnRootMismatch" indicates that volume's ownership and permissions will be changed only when permission and ownership of root directory does not match with expected permissions on the volume. This can help shorten the time it takes to change ownership and permissions of a volume. runAsGroup integer The GID to run the entrypoint of the container process. Uses runtime default if unset. May also be set in SecurityContext. If set in both SecurityContext and PodSecurityContext, the value specified in SecurityContext takes precedence for that container. Note that this field cannot be set when spec.os.name is windows. runAsNonRoot boolean Indicates that the container must run as a non-root user. 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. Defaults to user specified in image metadata if unspecified. May also be set in SecurityContext. If set in both SecurityContext and PodSecurityContext, the value specified in SecurityContext takes precedence for that container. Note that this field cannot be set when spec.os.name is windows. seLinuxOptions object SELinuxOptions are the labels to be applied to the container seccompProfile object SeccompProfile defines a pod/container's seccomp profile settings. Only one profile source may be set. supplementalGroups array (integer) A list of groups applied to the first process run in each container, in addition to the container's primary GID, the fsGroup (if specified), and group memberships defined in the container image for the uid of the container process. If unspecified, no additional groups are added to any container. Note that group memberships defined in the container image for the uid of the container process are still effective, even if they are not included in this list. Note that this field cannot be set when spec.os.name is windows. sysctls array Sysctls hold a list of namespaced sysctls used for the pod. Pods with unsupported sysctls (by the container runtime) might fail to launch. Note that this field cannot be set when spec.os.name is windows. sysctls[] object Sysctl defines a kernel parameter to be set windowsOptions object WindowsSecurityContextOptions contain Windows-specific options and credentials. 15.1.237. .spec.template.spec.securityContext.seLinuxOptions Description SELinuxOptions are the labels to be applied to the container Type object Property Type Description level string Level is SELinux level label that applies to the container. role string Role is a SELinux role label that applies to the container. type string Type is a SELinux type label that applies to the container. user string User is a SELinux user label that applies to the container. 15.1.238. .spec.template.spec.securityContext.seccompProfile Description SeccompProfile defines a pod/container's seccomp profile settings. Only one profile source may be set. Type object Required type Property Type Description localhostProfile string localhostProfile indicates a profile defined in a file on the node should be used. The profile must be preconfigured on the node to work. Must be a descending path, relative to the kubelet's configured seccomp profile location. Must be set if type is "Localhost". Must NOT be set for any other type. type string type indicates which kind of seccomp profile will be applied. Valid options are: Localhost - a profile defined in a file on the node should be used. RuntimeDefault - the container runtime default profile should be used. Unconfined - no profile should be applied. Possible enum values: - "Localhost" indicates a profile defined in a file on the node should be used. The file's location relative to <kubelet-root-dir>/seccomp. - "RuntimeDefault" represents the default container runtime seccomp profile. - "Unconfined" indicates no seccomp profile is applied (A.K.A. unconfined). 15.1.239. .spec.template.spec.securityContext.sysctls Description Sysctls hold a list of namespaced sysctls used for the pod. Pods with unsupported sysctls (by the container runtime) might fail to launch. Note that this field cannot be set when spec.os.name is windows. Type array 15.1.240. .spec.template.spec.securityContext.sysctls[] Description Sysctl defines a kernel parameter to be set Type object Required name value Property Type Description name string Name of a property to set value string Value of a property to set 15.1.241. .spec.template.spec.securityContext.windowsOptions Description WindowsSecurityContextOptions contain Windows-specific options and credentials. Type object Property Type Description gmsaCredentialSpec string GMSACredentialSpec is where the GMSA admission webhook ( https://github.com/kubernetes-sigs/windows-gmsa ) inlines the contents of the GMSA credential spec named by the GMSACredentialSpecName field. gmsaCredentialSpecName string GMSACredentialSpecName is the name of the GMSA credential spec to use. hostProcess boolean HostProcess determines if a container should be run as a 'Host Process' container. All of a Pod's containers must have the same effective HostProcess value (it is not allowed to have a mix of HostProcess containers and non-HostProcess containers). In addition, if HostProcess is true then HostNetwork must also be set to true. runAsUserName string The UserName in Windows to run the entrypoint of the container process. Defaults to the user specified in image metadata if unspecified. May also be set in PodSecurityContext. If set in both SecurityContext and PodSecurityContext, the value specified in SecurityContext takes precedence. 15.1.242. .spec.template.spec.tolerations Description If specified, the pod's tolerations. Type array 15.1.243. .spec.template.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. Possible enum values: - "NoExecute" Evict any already-running pods that do not tolerate the taint. Currently enforced by NodeController. - "NoSchedule" Do not allow new pods to schedule onto the node unless they tolerate the taint, but allow all pods submitted to Kubelet without going through the scheduler to start, and allow all already-running pods to continue running. Enforced by the scheduler. - "PreferNoSchedule" Like TaintEffectNoSchedule, but the scheduler tries not to schedule new pods onto the node, rather than prohibiting new pods from scheduling onto the node entirely. Enforced by the scheduler. 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. Possible enum values: - "Equal" - "Exists" 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. 15.1.244. .spec.template.spec.topologySpreadConstraints Description TopologySpreadConstraints describes how a group of pods ought to spread across topology domains. Scheduler will schedule pods in a way which abides by the constraints. All topologySpreadConstraints are ANDed. Type array 15.1.245. .spec.template.spec.topologySpreadConstraints[] Description TopologySpreadConstraint specifies how to spread matching pods among the given topology. Type object Required maxSkew topologyKey whenUnsatisfiable Property Type Description labelSelector LabelSelector 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. This is a beta field and requires the MinDomainsInPodTopologySpread feature gate to be enabled (enabled by default). 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. Possible enum values: - "Honor" means use this scheduling directive when calculating pod topology spread skew. - "Ignore" means ignore this scheduling directive when calculating pod topology spread skew. 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. Possible enum values: - "Honor" means use this scheduling directive when calculating pod topology spread skew. - "Ignore" means ignore this scheduling directive when calculating pod topology spread skew. 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. Possible enum values: - "DoNotSchedule" instructs the scheduler not to schedule the pod when constraints are not satisfied. - "ScheduleAnyway" instructs the scheduler to schedule the pod even if constraints are not satisfied. 15.1.246. .spec.template.spec.volumes Description List of volumes that can be mounted by containers belonging to the pod.
