Network holds cluster-wide information about the network. It is used to configure the desired network configuration, such as: IP address pools for services/pod IPs, network plugin, etc. Please view network.spec for an explanation on what applies when configuring this resource. TODO (csrwng): Add validation here to exclude changes that conflict with networking settings in the HostedCluster.Spec.Networking field.

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.

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.

This list may be empty if no updates are recommended, if the update service is unavailable, or if an invalid channel has been specified.

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.

Updating this field will trigger a rollout of the control plane. The behavior of the rollout will be driven by the ControllerAvailabilityPolicy and InfrastructureAvailabilityPolicy.

ClusterID uniquely identifies this cluster. This is expected to be an RFC4122 UUID value (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx in hexadecimal values). As with a Kubernetes metadata.uid, this ID uniquely identifies this cluster in space and time. This value identifies the cluster in metrics pushed to telemetry and metrics produced by the control plane operators. If a value is not specified, an ID is generated. After initial creation, the value is immutable.

Configuration specifies configuration for individual OCP components in the cluster, represented as embedded resources that correspond to the openshift configuration API.

AuditWebhook contains metadata for configuring an audit webhook endpoint for a cluster to process cluster audit events. It references a secret that contains the webhook information for the audit webhook endpoint. It is a secret because if the endpoint has mTLS the kubeconfig will contain client keys. The kubeconfig needs to be stored in the secret with a secret key name that corresponds to the constant AuditWebhookKubeconfigKey.

Platform contains platform-specific status of the HostedCluster

ReleaseImage is the release image applied to the hosted control plane.

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.
