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

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

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[]

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.

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.

Description

Type
object
PropertyTypeDescription

availableReplicas

integer

The number of available replicas (ready for at least minReadySeconds) for this MachineSet.

conditions

array

Conditions defines the current state of the MachineSet

conditions[]

object

Condition defines an observation of a Machine API resource operational state.

errorMessage

string

 

errorReason

string

In the event that there is a terminal problem reconciling the replicas, both ErrorReason and ErrorMessage will be set. 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.

PropertyTypeDescription

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.

fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. 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.
