cluster.x-k8s.io / v1alpha3 / MachinePool
- string
.apiVersion
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
- string
.kind
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
.metadata
- object
.spec
spec is the desired state of MachinePool.
- string required
.spec .clusterName
clusterName is the name of the Cluster this object belongs to.
- array
.spec .failureDomains
failureDomains is the list of failure domains this MachinePool should be attached to.
- integer
.spec .minReadySeconds
minReadySeconds is the minimum number of seconds for which a newly created machine instances should be ready. Defaults to 0 (machine instance will be considered available as soon as it is ready)
- array
.spec .providerIDList
providerIDList are the identification IDs of machine instances provided by the provider. This field must match the provider IDs as seen on the node objects corresponding to a machine pool’s machine instances.
- integer
.spec .replicas
replicas is the number of desired machines. Defaults to 1. This is a pointer to distinguish between explicit zero and not specified.
- object
.spec .strategy
strategy is the deployment strategy to use to replace existing machine instances with new ones.
- object
.spec .strategy .rollingUpdate
rollingUpdate is the rolling update config params. Present only if MachineDeploymentStrategyType = RollingUpdate.
- integer | string
.spec .strategy .rollingUpdate .maxSurge
maxSurge is 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.
- string
.spec .strategy .type
type of deployment. Currently the only supported strategy is “RollingUpdate”. Default is RollingUpdate.
- object required

- string
.spec .template .metadata .generateName
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

Deprecated: This field has no function and is going to be removed in a next release.
- string
.spec .template .metadata .namespace
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
Deprecated: This field has no function and is going to be removed in a next release.

.spec .template .spec .providerID
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.

- string required
.status .conditions[] .type
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.
