Chapter 10. Machine [machine.openshift.io/v1beta1] Description Machine is the Schema for the machines API Compatibility level 2: Stable within a major release for a minimum of 9 months or 3 minor releases (whichever is longer). Type object 10.1. 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 MachineSpec defines the desired state of Machine status object MachineStatus defines the observed state of Machine 10.1.1. .spec Description MachineSpec defines the desired state of Machine Type object Property Type Description lifecycleHooks object LifecycleHooks allow users to pause operations on the machine at certain predefined points within the machine lifecycle. metadata object ObjectMeta will autopopulate the Node created. Use this to indicate what labels, annotations, name prefix, etc., should be used when creating the Node. providerID string ProviderID is the identification ID of the machine provided by the provider. This field must match the provider ID as seen on the node object corresponding to this machine. This field is required by higher level consumers of cluster-api. Example use case is cluster autoscaler with cluster-api as provider. Clean-up logic in the autoscaler compares machines to nodes to find out machines at provider which could not get registered as Kubernetes nodes. With cluster-api as a generic out-of-tree provider for autoscaler, this field is required by autoscaler to be able to have a provider view of the list of machines. Another list of nodes is queried from the k8s apiserver and then a comparison is done to find out unregistered machines and are marked for delete. This field will be set by the actuators and consumed by higher level entities like autoscaler that will be interfacing with cluster-api as generic provider. providerSpec object ProviderSpec details Provider-specific configuration to use during node creation. taints array The list of the taints to be applied to the corresponding Node in additive manner. This list will not overwrite any other taints added to the Node on an ongoing basis by other entities. These taints should be actively reconciled e.g. if you ask the machine controller to apply a taint and then manually remove the taint the machine controller will put it back) but not have the machine controller remove any taints taints[] object The node this Taint is attached to has the "effect" on any pod that does not tolerate the Taint. 10.1.2. .spec.lifecycleHooks Description LifecycleHooks allow users to pause operations on the machine at certain predefined points within the machine lifecycle. Type object Property Type Description preDrain array PreDrain hooks prevent the machine from being drained. This also blocks further lifecycle events, such as termination. preDrain[] object LifecycleHook represents a single instance of a lifecycle hook preTerminate array PreTerminate hooks prevent the machine from being terminated. PreTerminate hooks be actioned after the Machine has been drained. preTerminate[] object LifecycleHook represents a single instance of a lifecycle hook 10.1.3. .spec.lifecycleHooks.preDrain Description PreDrain hooks prevent the machine from being drained. This also blocks further lifecycle events, such as termination. Type array 10.1.4. .spec.lifecycleHooks.preDrain[] Description LifecycleHook represents a single instance of a lifecycle hook Type object Required name owner Property Type Description name string Name defines a unique name for the lifcycle hook. The name should be unique and descriptive, ideally 1-3 words, in CamelCase or it may be namespaced, eg. foo.example.com/CamelCase. Names must be unique and should only be managed by a single entity. owner string Owner defines the owner of the lifecycle hook. This should be descriptive enough so that users can identify who/what is responsible for blocking the lifecycle. This could be the name of a controller (e.g. clusteroperator/etcd) or an administrator managing the hook. 10.1.5. .spec.lifecycleHooks.preTerminate Description PreTerminate hooks prevent the machine from being terminated. PreTerminate hooks be actioned after the Machine has been drained. Type array 10.1.6. .spec.lifecycleHooks.preTerminate[] Description LifecycleHook represents a single instance of a lifecycle hook Type object Required name owner Property Type Description name string Name defines a unique name for the lifcycle hook. The name should be unique and descriptive, ideally 1-3 words, in CamelCase or it may be namespaced, eg. foo.example.com/CamelCase. Names must be unique and should only be managed by a single entity. owner string Owner defines the owner of the lifecycle hook. This should be descriptive enough so that users can identify who/what is responsible for blocking the lifecycle. This could be the name of a controller (e.g. clusteroperator/etcd) or an administrator managing the hook. 10.1.7. .spec.metadata Description ObjectMeta will autopopulate the Node created. Use this to indicate what labels, annotations, name prefix, etc., should be used when creating the Node. Type object Property Type Description annotations object (string) Annotations is an unstructured key value map stored with a resource that may be set by external tools to store and retrieve arbitrary metadata. They are not queryable and should be preserved when modifying objects. More info: http://kubernetes.io/docs/user-guide/annotations generateName string GenerateName is an optional prefix, used by the server, to generate a unique name ONLY IF the Name field has not been provided. If this field is used, the name returned to the client will be different than the name passed. This value will also be combined with a unique suffix. The provided value has the same validation rules as the Name field, and may be truncated by the length of the suffix required to make the value unique on the server. If this field is specified and the generated name exists, the server will NOT return a 409 - instead, it will either return 201 Created or 500 with Reason ServerTimeout indicating a unique name could not be found in the time allotted, and the client should retry (optionally after the time indicated in the Retry-After header). Applied only if Name is not specified. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#idempotency labels object (string) Map of string keys and values that can be used to organize and categorize (scope and select) objects. May match selectors of replication controllers and services. More info: http://kubernetes.io/docs/user-guide/labels name string Name must be unique within a namespace. Is required when creating resources, although some resources may allow a client to request the generation of an appropriate name automatically. Name is primarily intended for creation idempotence and configuration definition. Cannot be updated. More info: http://kubernetes.io/docs/user-guide/identifiers#names namespace string Namespace defines the space within each name must be unique. An empty namespace is equivalent to the "default" namespace, but "default" is the canonical representation. Not all objects are required to be scoped to a namespace - the value of this field for those objects will be empty. Must be a DNS_LABEL. Cannot be updated. More info: http://kubernetes.io/docs/user-guide/namespaces ownerReferences array List of objects depended by this object. If ALL objects in the list have been deleted, this object will be garbage collected. If this object is managed by a controller, then an entry in this list will point to this controller, with the controller field set to true. There cannot be more than one managing controller. ownerReferences[] object OwnerReference contains enough information to let you identify an owning object. An owning object must be in the same namespace as the dependent, or be cluster-scoped, so there is no namespace field. 10.1.8. .spec.metadata.ownerReferences Description List of objects depended by this object. If ALL objects in the list have been deleted, this object will be garbage collected. If this object is managed by a controller, then an entry in this list will point to this controller, with the controller field set to true. There cannot be more than one managing controller. Type array 10.1.9. .spec.metadata.ownerReferences[] Description OwnerReference contains enough information to let you identify an owning object. An owning object must be in the same namespace as the dependent, or be cluster-scoped, so there is no namespace field. Type object Required apiVersion kind name uid Property Type Description apiVersion string API version of the referent. blockOwnerDeletion boolean If true, AND if the owner has the "foregroundDeletion" finalizer, then the owner cannot be deleted from the key-value store until this reference is removed. See https://kubernetes.io/docs/concepts/architecture/garbage-collection/#foreground-deletion for how the garbage collector interacts with this field and enforces the foreground deletion. Defaults to false. To set this field, a user needs "delete" permission of the owner, otherwise 422 (Unprocessable Entity) will be returned. controller boolean If true, this reference points to the managing controller. kind string Kind of the referent. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds name string Name of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names#names uid string UID of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names#uids 10.1.10. .spec.providerSpec Description ProviderSpec details Provider-specific configuration to use during node creation. Type object Property Type Description value `` Value is an inlined, serialized representation of the resource configuration. It is recommended that providers maintain their own versioned API types that should be serialized/deserialized from this field, akin to component config. 10.1.11. .spec.taints Description The list of the taints to be applied to the corresponding Node in additive manner. This list will not overwrite any other taints added to the Node on an ongoing basis by other entities. These taints should be actively reconciled e.g. if you ask the machine controller to apply a taint and then manually remove the taint the machine controller will put it back) but not have the machine controller remove any taints Type array 10.1.12. .spec.taints[] Description The node this Taint is attached to has the "effect" on any pod that does not tolerate the Taint. Type object Required effect key Property Type Description effect string Required. The effect of the taint on pods that do not tolerate the taint. Valid effects are NoSchedule, PreferNoSchedule and NoExecute. key string Required. The taint key to be applied to a node. timeAdded string TimeAdded represents the time at which the taint was added. It is only written for NoExecute taints. value string The taint value corresponding to the taint key. 10.1.13. .status Description MachineStatus defines the observed state of Machine Type object Property Type Description addresses array Addresses is a list of addresses assigned to the machine. Queried from cloud provider, if available. addresses[] object NodeAddress contains information for the node's address. conditions array Conditions defines the current state of the Machine conditions[] object Condition defines an observation of a Machine API resource operational state. errorMessage string ErrorMessage will be set in the event that there is a terminal problem reconciling the Machine and will contain a more verbose string suitable for logging and human consumption. This field should not be set for transitive errors that a controller faces that are expected to be fixed automatically over time (like service outages), but instead indicate that something is fundamentally wrong with the Machine's spec or the configuration of the controller, and that manual intervention is required. Examples of terminal errors would be invalid combinations of settings in the spec, values that are unsupported by the controller, or the responsible controller itself being critically misconfigured. Any transient errors that occur during the reconciliation of Machines can be added as events to the Machine object and/or logged in the controller's output. errorReason string ErrorReason will be set in the event that there is a terminal problem reconciling the Machine and will contain a succinct value suitable for machine interpretation. This field should not be set for transitive errors that a controller faces that are expected to be fixed automatically over time (like service outages), but instead indicate that something is fundamentally wrong with the Machine's spec or the configuration of the controller, and that manual intervention is required. Examples of terminal errors would be invalid combinations of settings in the spec, values that are unsupported by the controller, or the responsible controller itself being critically misconfigured. Any transient errors that occur during the reconciliation of Machines can be added as events to the Machine object and/or logged in the controller's output. lastOperation object LastOperation describes the last-operation performed by the machine-controller. This API should be useful as a history in terms of the latest operation performed on the specific machine. It should also convey the state of the latest-operation for example if it is still on-going, failed or completed successfully. lastUpdated string LastUpdated identifies when this status was last observed. nodeRef object NodeRef will point to the corresponding Node if it exists. phase string Phase represents the current phase of machine actuation. One of: Failed, Provisioning, Provisioned, Running, Deleting providerStatus `` ProviderStatus details a Provider-specific status. It is recommended that providers maintain their own versioned API types that should be serialized/deserialized from this field. 10.1.14. .status.addresses Description Addresses is a list of addresses assigned to the machine. Queried from cloud provider, if available. Type array 10.1.15. .status.addresses[] Description NodeAddress contains information for the node's address. Type object Required address type Property Type Description address string The node address. type string Node address type, one of Hostname, ExternalIP or InternalIP. 10.1.16. .status.conditions Description Conditions defines the current state of the Machine Type array 10.1.17. .status.conditions[] Description Condition defines an observation of a Machine API resource operational state. Type object Property Type Description lastTransitionTime string Last time the condition transitioned from one status to another. This should be when the underlying condition changed. If that is not known, then using the time when the API field changed is acceptable. message string A human readable message indicating details about the transition. This field may be empty. reason string The reason for the condition's last transition in CamelCase. The specific API may choose whether or not this field is considered a guaranteed API. This field may not be empty. severity string Severity provides an explicit classification of Reason code, so the users or machines can immediately understand the current situation and act accordingly. The Severity field MUST be set only when Status=False. status string Status of the condition, one of True, False, Unknown. type string Type of condition in CamelCase or in foo.example.com/CamelCase. Many .condition.type values are consistent across resources like Available, but because arbitrary conditions can be useful (see .node.status.conditions), the ability to deconflict is important. 10.1.18. .status.lastOperation Description LastOperation describes the last-operation performed by the machine-controller. This API should be useful as a history in terms of the latest operation performed on the specific machine. It should also convey the state of the latest-operation for example if it is still on-going, failed or completed successfully. Type object Property Type Description description string Description is the human-readable description of the last operation. lastUpdated string LastUpdated is the timestamp at which LastOperation API was last-updated. state string State is the current status of the last performed operation. E.g. Processing, Failed, Successful etc type string Type is the type of operation which was last performed. E.g. Create, Delete, Update etc 10.1.19. .status.nodeRef Description NodeRef will point to the corresponding Node if it exists. Type object Property Type Description apiVersion string API version of the referent. fieldPath string If referring to a piece of an object instead of an entire object, this string should contain a valid JSON/Go field access statement, such as desiredState.manifest.containers[2]. For example, if the object reference is to a container within a pod, this would take on a value like: "spec.containers{name}" (where "name" refers to the name of the container that triggered the event) or if no container name is specified "spec.containers[2]" (container with index 2 in this pod). This syntax is chosen only to have some well-defined way of referencing a part of an object. TODO: this design is not final and this field is subject to change in the future. kind string Kind of the referent. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds name string Name of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names/#names namespace string Namespace of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/namespaces/ resourceVersion string Specific resourceVersion to which this reference is made, if any. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#concurrency-control-and-consistency uid string UID of the referent.
