Specification

Property Type Description

apiVersion

string

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

string

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

metadata

ObjectMeta_v2

Standard object’s metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata

spec

object

spec is the desired state of the cluster version - the operator will work to ensure that the desired version is applied to the cluster.

status

object

status contains information about the available updates and any in-progress updates.

.spec

Description

spec is the desired state of the cluster version - the operator will work to ensure that the desired version is applied to the cluster.

Type

object

Required
  • clusterID

Property Type Description

capabilities

object

capabilities configures the installation of optional, core cluster components. A null value here is identical to an empty object; see the child properties for default semantics.

channel

string

channel is an identifier for explicitly requesting that a non-default set of updates be applied to this cluster. The default channel will be contain stable updates that are appropriate for production clusters.

clusterID

string

clusterID uniquely identifies this cluster. This is expected to be an RFC4122 UUID value (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx in hexadecimal values). This is a required field.

desiredUpdate

object

desiredUpdate is an optional field that indicates the desired value of the cluster version. Setting this value will trigger an upgrade (if the current version does not match the desired version). The set of recommended update values is listed as part of available updates in status, and setting values outside that range may cause the upgrade to fail. You may specify the version field without setting image if an update exists with that version in the availableUpdates or history. If an upgrade fails the operator will halt and report status about the failing component. Setting the desired update value back to the previous version will cause a rollback to be attempted. Not all rollbacks will succeed.

overrides

array

overrides is list of overides for components that are managed by cluster version operator. Marking a component unmanaged will prevent the operator from creating or updating the object.

overrides[]

object

ComponentOverride allows overriding cluster version operator’s behavior for a component.

upstream

string

upstream may be used to specify the preferred update server. By default it will use the appropriate update server for the cluster and region.

.spec.capabilities

Description

capabilities configures the installation of optional, core cluster components. A null value here is identical to an empty object; see the child properties for default semantics.

Type

object

Property Type Description

additionalEnabledCapabilities

array (string)

additionalEnabledCapabilities extends the set of managed capabilities beyond the baseline defined in baselineCapabilitySet. The default is an empty set.

baselineCapabilitySet

string

baselineCapabilitySet selects an initial set of optional capabilities to enable, which can be extended via additionalEnabledCapabilities. If unset, the cluster will choose a default, and the default may change over time. The current default is vCurrent.

.spec.desiredUpdate

Description

desiredUpdate is an optional field that indicates the desired value of the cluster version. Setting this value will trigger an upgrade (if the current version does not match the desired version). The set of recommended update values is listed as part of available updates in status, and setting values outside that range may cause the upgrade to fail. You may specify the version field without setting image if an update exists with that version in the availableUpdates or history. If an upgrade fails the operator will halt and report status about the failing component. Setting the desired update value back to the previous version will cause a rollback to be attempted. Not all rollbacks will succeed.

Type

object

Property Type Description

force

boolean

force allows an administrator to update to an image that has failed verification or upgradeable checks. This option should only be used when the authenticity of the provided image has been verified out of band because the provided image will run with full administrative access to the cluster. Do not use this flag with images that comes from unknown or potentially malicious sources.

image

string

image is a container image location that contains the update. When this field is part of spec, image is optional if version is specified and the availableUpdates field contains a matching version.

version

string

version is a semantic versioning identifying the update version. When this field is part of spec, version is optional if image is specified.

.spec.overrides

Description

overrides is list of overides for components that are managed by cluster version operator. Marking a component unmanaged will prevent the operator from creating or updating the object.

Type

array

.spec.overrides[]

Description

ComponentOverride allows overriding cluster version operator’s behavior for a component.

Type

object

Required
  • group

  • kind

  • name

  • namespace

  • unmanaged

Property Type Description

group

string

group identifies the API group that the kind is in.

kind

string

kind indentifies which object to override.

name

string

name is the component’s name.

namespace

string

namespace is the component’s namespace. If the resource is cluster scoped, the namespace should be empty.

unmanaged

boolean

unmanaged controls if cluster version operator should stop managing the resources in this cluster. Default: false

.status

Description

status contains information about the available updates and any in-progress updates.

Type

object

Required
  • desired

  • observedGeneration

  • versionHash

Property Type Description

availableUpdates

``

availableUpdates contains updates recommended for this cluster. Updates which appear in conditionalUpdates but not in availableUpdates may expose this cluster to known issues. This list may be empty if no updates are recommended, if the update service is unavailable, or if an invalid channel has been specified.

capabilities

object

capabilities describes the state of optional, core cluster components.

conditionalUpdates

array

conditionalUpdates contains the list of updates that may be recommended for this cluster if it meets specific required conditions. Consumers interested in the set of updates that are actually recommended for this cluster should use availableUpdates. This list may be empty if no updates are recommended, if the update service is unavailable, or if an empty or invalid channel has been specified.

conditionalUpdates[]

object

ConditionalUpdate represents an update which is recommended to some clusters on the version the current cluster is reconciling, but which may not be recommended for the current cluster.

conditions

array

conditions provides information about the cluster version. The condition "Available" is set to true if the desiredUpdate has been reached. The condition "Progressing" is set to true if an update is being applied. The condition "Degraded" is set to true if an update is currently blocked by a temporary or permanent error. Conditions are only valid for the current desiredUpdate when metadata.generation is equal to status.generation.

conditions[]

object

ClusterOperatorStatusCondition represents the state of the operator’s managed and monitored components.

desired

object

desired is the version that the cluster is reconciling towards. If the cluster is not yet fully initialized desired will be set with the information available, which may be an image or a tag.

history

array

history contains a list of the most recent versions applied to the cluster. This value may be empty during cluster startup, and then will be updated when a new update is being applied. The newest update is first in the list and it is ordered by recency. Updates in the history have state Completed if the rollout completed - if an update was failing or halfway applied the state will be Partial. Only a limited amount of update history is preserved.

history[]

object

UpdateHistory is a single attempted update to the cluster.

observedGeneration

integer

observedGeneration reports which version of the spec is being synced. If this value is not equal to metadata.generation, then the desired and conditions fields m
