ClusterVersion [config.openshift.io/v1]

Description

ClusterVersion is the configuration for the ClusterVersionOperator. This is where parameters related to automatic updates can be set.

Type

object

Required

  • spec

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 meta/v1

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

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.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, does not appear in the availableUpdates list, or otherwise would be blocked by normal protections on update. 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. This flag does not override other forms of consistency checking that are required before a new update is deployed.

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.

If 'true', then the output is pretty printed.
HTTP method

DELETE

Description

delete collection of ClusterVersion

Table 2. Query parameters
Parameter Type Description

allowWatchBookmarks

boolean

allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored. If the feature gate WatchBookmarks is not enabled in apiserver, this field is ignored.

continue

string

The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a previous query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the next key, but from the latest snapshot, which is inconsistent from the previous list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the "next key".

This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications.

fieldSelector

string

A selector to restrict the list of returned objects by their fields. Defaults to everything.

labelSelector

string

A selector to restrict the list of returned objects by their labels. Defaults to everything.

limit

integer

limit is a maximum number of responses to return for a list call. If more items exist, the server will set the `continue` field on the list metadata to a value that can be used with the same initial query to retrieve the next set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true.

The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned.

resourceVersion

string

resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details.

Defaults to unset

resourceVersionMatch

string

resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details.

Defaults to unset

timeoutSeconds

integer

Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity.

watch

boolean

Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion.
