object
Property | Type | Description |
---|---|---|
|
|
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
template
Property | Type | Description |
---|---|---|
|
|
ClusterName is the name of the Cluster this object belongs to. |
|
|
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) |
|
|
Indicates that the deployment is paused. |
|
|
The maximum time in seconds for a deployment to make progress before it is considered to be failed. The deployment controller will continue to process failed deployments and a condition with a ProgressDeadlineExceeded reason will be surfaced in the deployment status. Note that progress will not be estimated during the time a deployment is paused. Defaults to 600s. |
|
|
Number of desired machines. This is a pointer to distinguish between explicit zero and not specified. Defaults to: * if the Kubernetes autoscaler min size and max size annotations are set: - if it’s a new MachineDeployment, use min size - if the replicas field of the old MachineDeployment is < min size, use min size - if the replicas field of the old MachineDeployment is > max size, use max size - if the replicas field of the old MachineDeployment is in the (min size, max size) range, keep the value from the oldMD * otherwise use 1 Note: Defaulting will be run whenever the replicas field is not set: * A new MachineDeployment is created with replicas not set. * On an existing MachineDeployment the replicas field was first set and is now unset. Those cases are especially relevant for the following Kubernetes autoscaler use cases: * A new MachineDeployment is created and replicas should be managed by the autoscaler * An existing MachineDeployment which initially wasn’t controlled by the autoscaler should be later controlled by the autoscaler |
|
|
The number of old MachineSets to retain to allow rollback. This is a pointer to distinguish between explicit zero and not specified. Defaults to 1. |
|
|
RolloutAfter is a field to indicate a rollout should be performed after the specified time even if no changes have been made to the MachineDeployment. Example: In the YAML the time can be specified in the RFC3339 format. To specify the rolloutAfter target as March 9, 2023, at 9 am UTC use "2023-03-09T09:00:00Z". |

|
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. |

|
|
DeletePolicy defines the policy used by the MachineDeployment to identify nodes to delete when downscaling. Valid values are "Random, "Newest", "Oldest" When no value is supplied, the default DeletePolicy of MachineSet is used |
|
|
The maximum number of machines that can be scheduled above the desired number of machines. Value can be an absolute number (ex: 5) or a percentage of desired machines (ex: 10%). This can not be 0 if MaxUnavailable is 0. Absolute number is calculated from percentage by rounding up. Defaults to 1. Example: when this is set to 30%, the new MachineSet can be scaled up immediately when the rolling update starts, such that the total number of old and new machines do not exceed 130% of desired machines. Once old machines have been killed, new MachineSet can be scaled up further, ensuring that total number of machines running at any time during the update is at most 130% of desired machines. |
|
|
The maximum number of machines that can be unavailable during the update. Value can be an absolute number (ex: 5) or a percentage of desired machines (ex: 10%). Absolute number is calculated from percentage by rounding down. This can not be 0 if MaxSurge is 0. Defaults to 0. Example: when this is set to 30%, the old MachineSet can be scaled down to 70% of desired machines immediately when the rolling update starts. Once new machines are ready, old MachineSet can be scaled down further, followed by scaling up the new MachineSet, ensuring that the total number of machines available at all times during the update is at least 70% of desired machines. |
Template describes the machines that will be created.

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. |

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. |
