Machine is the Schema for the machines API
5 top-level fields · last changed in Cluster API v0.2.3
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/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/api-conventions.md#types-kinds
MachineSpec defines the desired state of Machine
Bootstrap is a reference to a local struct which encapsulates fields to configure the Machine’s bootstrapping mechanism.
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.Data without the need of a controller.
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.

Data contains the bootstrap data, such as cloud-init details scripts. If nil, the Machine should remain in the Pending state.
InfrastructureRef is a required reference to a custom resource offered by an infrastructure provider.

DEPRECATED: ObjectMeta has no function and isn't used anywhere.
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 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/api-conventions.md#idempotency
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 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 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
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.
API version of the referent.
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. Defaults to false. To set this field, a user needs "delete" permission of the owner, otherwise 422 (Unprocessable Entity) will be returned.
If true, this reference points to the managing controller.

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.
MachineStatus defines the observed state of Machine
Addresses is a list of addresses assigned to the machine. This field is copied from the infrastructure provider reference.
The machine address.
Machine address type, one of Hostname, ExternalIP or InternalIP.
BootstrapReady is the state of the bootstrap provider.
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 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.

InfrastructureReady is the state of the infrastructure provider.
LastUpdated identifies when this status was last observed.
NodeRef will point to the corresponding Node if it exists.

Phase represents the current phase of machine actuation. E.g. Pending, Running, Terminating, Failed etc.
Version specifies the current version of Kubernetes running on the corresponding Node. This is meant to be a means of bubbling up status from the Node to the Machine. It is entirely optional, but useful for end-user UX if it’s present.
