Chapter 10. MachineSet [machine.openshift.io/v1beta1] Description MachineSet ensures that a specified number of machines replicas are running at any given time. 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#metadata spec object MachineSetSpec defines the desired state of MachineSet status object MachineSetStatus defines the observed state of MachineSet 10.1.1. .spec Description MachineSetSpec defines the desired state of MachineSet Type object Property Type Description deletePolicy string DeletePolicy defines the policy used to identify nodes to delete when downscaling. Defaults to "Random". Valid values are "Random, "Newest", "Oldest" minReadySeconds integer MinReadySeconds is the minimum number of seconds for which a newly created machine should be ready. Defaults to 0 (machine 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. selector object Selector is a label query over machines that should match the replica count. Label keys and values that must match in order to be controlled by this MachineSet. It must match the machine template's labels. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/#label-selectors template object Template is the object that describes the machine that will be created if insufficient replicas are detected. 10.1.2. .spec.selector Description Selector is a label query over machines that should match the replica count. Label keys and values that must match in order to be controlled by this MachineSet. It must match the machine template's labels. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/#label-selectors 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. 10.1.3. .spec.selector.matchExpressions Description matchExpressions is a list of label selector requirements. The requirements are ANDed. Type array 10.1.4. .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. 10.1.5. .spec.template Description Template is the object that describes the machine that will be created if insufficient replicas are detected. Type object Property Type Description metadata object 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 machine.

More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata 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. 10.1.7. .spec.template.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 10.1.8. .spec.template.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://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#spec-and-status 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. 10.1.10. .spec.template.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.

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. 10.1.19. .spec.template.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.

ErrorReason will be populated with a succinct value suitable for machine interpretation, while ErrorMessage will contain a more verbose string suitable for logging and human consumption. These fields 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 MachineTemplate's spec or the configuration of the machine 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 machine controller, or the responsible machine controller itself being critically misconfigured. Any transient errors that occur during the reconciliation of Machines can be added as events to the MachineSet object and/or logged in the controller's output. fullyLabeledReplicas integer The number of replicas that have labels matching the labels of the machine template of the MachineSet. observedGeneration integer ObservedGeneration reflects the generation of the most recently observed MachineSet. readyReplicas integer The number of ready replicas for this MachineSet. A machine is considered ready when the node has been created and is "Ready". replicas integer Replicas is the most recently observed number of replicas. 10.1.22. .status.conditions Description Conditions defines the current state of the MachineSet Type array 10.1.23. .status.conditions[] Description Condition defines an observation of a Machine API resource operational state. Type object Required type 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. 10.2.

The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered. Table 10.28. Body parameters Parameter Type Description body MachineSet schema Table 10.29.
