|
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 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 |

object
clusterName
selector
Property | Type | Description |
---|---|---|
|
|
ClusterName is the name of the Cluster this object belongs to. |
|
|
DeletePolicy defines the policy used to identify nodes to delete when downscaling. Defaults to "Random". Valid values are "Random, "Newest", "Oldest" |
|
|
MinReadySeconds is the minimum number of seconds for which a Node for a newly created machine should be ready before considering the replica available. Defaults to 0 (machine will be considered available as soon as the Node is ready) |
|
|
Replicas is the number of desired replicas. This is a pointer to distinguish between explicit zero and unspecified. Defaults to: * if the Kubernetes autoscaler min size and max size annotations are set: - if it’s a new MachineSet, use min size - if the replicas field of the old MachineSet is < min size, use min size - if the replicas field of the old MachineSet is > max size, use max size - if the replicas field of the old MachineSet is in the (min size, max size) range, keep the value from the oldMS * otherwise use 1 Note: Defaulting will be run whenever the replicas field is not set: * A new MachineSet is created with replicas not set. * On an existing MachineSet the replicas field was first set and is now unset. Those cases are especially relevant for the following Kubernetes autoscaler use cases: * A new MachineSet is created and replicas should be managed by the autoscaler * An existing MachineSet which initially wasn’t controlled by the autoscaler should be later controlled by the autoscaler |
|
|
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 is the object that describes the machine that will be created if insufficient replicas are detected. Object references to custom resources are treated as templates. |

matchExpressions is a list of label selector requirements. The requirements are ANDed. |
|
|
A label selector requirement is a selector that contains values, a key, and an operator that relates the key and values. |
|
|
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. |

key
operator
Property | Type | Description |
---|---|---|
|
|
key is the label key that the selector applies to. |
|
|
operator represents a key’s relationship to a set of values. Valid operators are In, NotIn, Exists and DoesNotExist. |
|
|
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. |

bootstrap
clusterName
infrastructureRef
Property | Type | Description |
---|---|---|
|
|
Bootstrap is a reference to a local struct which encapsulates fields to configure the Machine’s bootstrapping mechanism. |
|
|
ClusterName is the name of the Cluster this object belongs to. |
|
|
FailureDomain is the failure domain the machine will be created in. Must match a key in the FailureDomains map stored on the cluster object. |
|
|
InfrastructureRef is a required reference to a custom resource offered by an infrastructure provider. |
|
|
NodeDeletionTimeout defines how long the controller will attempt to delete the Node that the Machine hosts after the Machine is marked for deletion. A duration of 0 will retry deletion indefinitely. Defaults to 10 seconds. |
|
|
NodeDrainTimeout is the total amount of time that the controller will spend on draining a node.
The default value is 0, meaning that the node can be drained without any time limitations.
NOTE: NodeDrainTimeout is different from |
|
|
NodeVolumeDetachTimeout is the total amount of time that the controller will spend on waiting for all volumes to be detached. The default value is 0, meaning that the volumes can be detached without any time limitations. |
|
|
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. |
|
|
Version defines the desired Kubernetes version. This field is meant to be optionally used by bootstrap providers. |
Bootstrap is a reference to a local struct which encapsulates fields to configure the Machine’s bootstrapping mechanism.
object
Property | Type | Description |
---|---|---|
|
|
ConfigRef is a reference to a bootstrap provider-specific resource that holds configuration details. The reference is optional to allow users/operators to specify Bootstrap.DataSecretName without the need of a controller. |
|
|
DataSecretName is the name of the secret that stores the bootstrap data script. If nil, the Machine should remain in the Pending state. |

API version of the referent. |
|
|
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. |

MachineSetStatus defines the observed state of MachineSet.
object
Property | Type | Description |
---|---|---|
|
|
The number of available replicas (ready for at least minReadySeconds) for this MachineSet. |
|
|
Conditions defines current service state of the MachineSet. |
|
|
Condition defines an observation of a Cluster API resource operational state. |
|
|
|
|
|
In the event that there is a terminal problem reconciling the replicas, both FailureReason and FailureMessage will be set. FailureReason will be populated with a succinct value suitable for machine interpretation, while FailureMessage 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. |
|
|
The number of replicas that have labels matching the labels of the machine template of the MachineSet. |
|
|
ObservedGeneration reflects the generation of the most recently observed MachineSet. |
|
|
The number of ready replicas for this MachineSet. A machine is considered ready when the node has been created and is "Ready". |
|
|
Replicas is the most recently observed number of replicas. |
|
|
Selector is the same as the label selector but in the string format to avoid introspection by clients. The string will be in the same format as the query-param syntax. More info about label selectors: http://kubernetes.io/docs/user-guide/labels#label-selectors |
Conditions defines current service state of the MachineSet.
array

object
lastTransitionTime
status
type
Property | Type | Description |
---|---|---|
|
|
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. |
|
|
A human readable message indicating details about the transition. This field may be empty. |
|
|
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 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 of the condition, one of True, False, Unknown. |
|
|
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. |
