Chapter 1. Operator APIs

Authentication provides information to configure an operator to manage authentication.

Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer).

ClusterCSIDriver object allows management and configuration of a CSI driver operator installed by default in OpenShift. Name of the object must be name of the CSI driver it operates. See CSIDriverName type for list of allowed values.

Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer).

Console provides a means to configure an operator to manage the console.

Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer).

Config specifies the behavior of the config operator which is responsible for creating the initial configuration of other components on the cluster. The operator also handles installation, migration or synchronization of cloud configurations for AWS and Azure cloud based clusters

Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer).

Config is the configuration object for a registry instance managed by the registry operator

Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer).

CSISnapshotController provides a means to configure an operator to manage the CSI snapshots. cluster is the canonical name.

Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer).

DNSRecord is a DNS record managed in the zones defined by dns.config.openshift.io/cluster .spec.publicZone and .spec.privateZone.

Cluster admin manipulation of this resource is not supported. This resource is only for internal communication of OpenShift operators.

If DNSManagementPolicy is "Unmanaged", the operator will not be responsible for managing the DNS records on the cloud provider.

Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer).

Etcd provides information to configure an operator to manage etcd.

Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer).

ImageContentSourcePolicy holds cluster-wide information about how to handle registry mirror rules. When multiple policies are defined, the outcome of the behavior is defined on each field.

Compatibility level 4: No compatibility is provided, the API can change at any point for any reason. These capabilities should not be used by applications needing long term support.

ImagePruner is the configuration object for an image registry pruner managed by the registry operator.

Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer).

IngressController describes a managed ingress controller for the cluster. The controller can service OpenShift Route and Kubernetes Ingress resources.

When an IngressController is created, a new ingress controller deployment is created to allow external traffic to reach the services that expose Ingress or Route resources. Updating this resource may lead to disruption for public facing network connections as a new ingress controller revision may be rolled out.

Whenever possible, sensible defaults for the platform are used. See each field for more details.

Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer).

KubeAPIServer provides information to configure an operator to manage kube-apiserver.

Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer).

KubeControllerManager provides information to configure an operator to manage kube-controller-manager.

Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer).

KubeScheduler provides information to configure an operator to manage scheduler.

Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer).

KubeStorageVersionMigrator provides information to configure an operator to manage kube-storage-version-migrator.

Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer).

MachineConfiguration provides information to configure an operator to manage Machine Configuration.

Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer).

Network describes the cluster’s desired network configuration. It is consumed by the cluster-network-operator.

Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer).

OpenShiftAPIServer provides information to configure an operator to manage openshift-apiserver.

Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer).

OpenShiftControllerManager provides information to configure an operator to manage openshift-controller-manager.

Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer).

OperatorPKI is a simple certificate authority. It is not intended for external use - rather, it is internal to the network operator. The CNO creates a CA and a certificate signed by that CA. The certificate has both ClientAuth and ServerAuth extended usages enabled.

More specifically, given an OperatorPKI with <name>, the CNO will manage:

The CA certificate will have a validity of 10 years, rotated after 9. The target certificate will have a validity of 6 months, rotated after 3

The CA certificate will have a CommonName of "<namespace>_<name>-ca@<timestamp>", where <timestamp> is the last rotation time.

Storage provides a means to configure an operator to manage the cluster storage operator. cluster is the canonical name.

Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer).
