object
spec
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
clusterID
Property | Type | Description |
---|---|---|
|
|
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 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 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 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. |
|
|
ComponentOverride allows overriding cluster version operator’s behavior for a component. |
|
|
upstream may be used to specify the preferred update server. By default it will use the appropriate update server for the cluster and region. |
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.

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

status contains information about the available updates and any in-progress updates.
object
desired
observedGeneration
versionHash
Property | Type | Description |
---|---|---|
|
`` |
availableUpdates contains the list of updates that are appropriate for this cluster. This list may be empty if no updates are recommended, if the update service is unavailable, or if an invalid channel has been specified. |
|
|
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. |
|
|
ClusterOperatorStatusCondition represents the state of the operator’s managed and monitored components. |
|
|
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 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. |
|
|
UpdateHistory is a single attempted update to the cluster. |
|
|
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 may represent a previous version. |
|
|
versionHash is a fingerprint of the content that the cluster will be updated with. It is used by the operator to avoid unnecessary work and is for internal use only. |
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.

|
|
image is a container image location that contains the update. This value is always populated. |
|
|
startedTime is the time at which the update was started. |
|
|
state reflects whether the update was fully applied. The Partial state indicates the update is not fully applied, while the Completed state indicates the update was successfully rolled out at least once (all parts of the update successfully applied). |
|
|
verified indicates whether the provided update was properly verified before it was installed. If this is false the cluster may not be trusted. |

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. |
|
|
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. |
|
|
A selector to restrict the list of returned objects by their fields. Defaults to everything. |
|
|
A selector to restrict the list of returned objects by their labels. Defaults to everything. |
|
|
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 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 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 |
|
|
Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity. |
