HyperShift API Reference

Packages:

• hypershift.openshift.io/v1alpha1

hypershift.openshift.io/v1alpha1

Package v1alpha1 contains the HyperShift API.

The HyperShift API enables creating and managing lightweight, flexible, heterogeneous OpenShift clusters at scale.

HyperShift clusters are deployed in a topology which isolates the “control plane” (e.g. etcd, the API server, controller manager, etc.) from the “data plane” (e.g. worker nodes and their kubelets, and the infrastructure on which they run). This enables “hosted control plane as a service” use cases.

##HostedCluster { #hypershift.openshift.io/v1alpha1.HostedCluster }

HostedCluster is the primary representation of a HyperShift cluster and encapsulates the control plane and common data plane configuration. Creating a HostedCluster results in a fully functional OpenShift control plane with no attached nodes. To support workloads (e.g. pods), a HostedCluster may have one or more associated NodePool resources.

Field	Description
apiVersion string	hypershift.openshift.io/v1alpha1
kind string	HostedCluster
metadata Kubernetes meta/v1.ObjectMeta	Refer to the Kubernetes API documentation for the fields of the metadata field.
spec HostedClusterSpec	Spec is the desired behavior of the HostedCluster. release Release Release specifies the desired OCP release payload for the hosted cluster. 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 string (Optional) 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. infraID string (Optional) InfraID is a globally unique identifier for the cluster. This identifier will be used to associate various cloud resources with the HostedCluster and its associated NodePools. platform PlatformSpec Platform specifies the underlying infrastructure provider for the cluster and is used to configure platform specific behavior. controllerAvailabilityPolicy AvailabilityPolicy (Optional) ControllerAvailabilityPolicy specifies the availability policy applied to critical control plane components. The default value is SingleReplica. Value must be one of: "HighlyAvailable", "SingleReplica" infrastructureAvailabilityPolicy AvailabilityPolicy (Optional) InfrastructureAvailabilityPolicy specifies the availability policy applied to infrastructure services which run on cluster nodes. The default value is SingleReplica. Value must be one of: "HighlyAvailable", "SingleReplica" dns DNSSpec DNS specifies DNS configuration for the cluster. networking ClusterNetworking Networking specifies network configuration for the cluster. autoscaling ClusterAutoscaling (Optional) Autoscaling specifies auto-scaling behavior that applies to all NodePools associated with the control plane. etcd EtcdSpec Etcd specifies configuration for the control plane etcd cluster. The default ManagementType is Managed. Once set, the ManagementType cannot be changed. services []ServicePublishingStrategyMapping Services specifies how individual control plane services are published from the hosting cluster of the control plane. If a given service is not present in this list, it will be exposed publicly by default. pullSecret Kubernetes core/v1.LocalObjectReference PullSecret references a pull secret to be injected into the container runtime of all cluster nodes. The secret must have a key named “.dockerconfigjson” whose value is the pull secret JSON. sshKey Kubernetes core/v1.LocalObjectReference SSHKey references an SSH key to be injected into all cluster node sshd servers. The secret must have a single key “id_rsa.pub” whose value is the public part of an SSH key. issuerURL string (Optional) IssuerURL is an OIDC issuer URL which is used as the issuer in all ServiceAccount tokens generated by the control plane API server. The default value is kubernetes.default.svc, which only works for in-cluster validation. serviceAccountSigningKey Kubernetes core/v1.LocalObjectReference (Optional) ServiceAccountSigningKey is a reference to a secret containing the private key used by the service account token issuer. The secret is expected to contain a single key named “key”. If not specified, a service account signing key will be generated automatically for the cluster. When specifying a service account signing key, a IssuerURL must also be specified. configuration ClusterConfiguration (Optional) Configuration specifies configuration for individual OCP components in the cluster, represented as embedded resources that correspond to the openshift configuration API. auditWebhook Kubernetes core/v1.LocalObjectReference (Optional) 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. This field is currently only supported on the IBMCloud platform. imageContentSources []ImageContentSource (Optional) ImageContentSources specifies image mirrors that can be used by cluster nodes to pull content. additionalTrustBundle Kubernetes core/v1.LocalObjectReference (Optional) AdditionalTrustBundle is a reference to a ConfigMap containing a PEM-encoded X.509 certificate bundle that will be added to the hosted controlplane and nodes secretEncryption SecretEncryptionSpec (Optional) SecretEncryption specifies a Kubernetes secret encryption strategy for the control plane. fips bool (Optional) FIPS indicates whether this cluster’s nodes will be running in FIPS mode. If set to true, the control plane’s ignition server will be configured to expect that nodes joining the cluster will be FIPS-enabled. pausedUntil string (Optional) PausedUntil is a field that can be used to pause reconciliation on a resource. Either a date can be provided in RFC3339 format or a boolean. If a date is provided: reconciliation is paused on the resource until that date. If the boolean true is provided: reconciliation is paused on the resource until the field is removed. olmCatalogPlacement OLMCatalogPlacement (Optional) OLMCatalogPlacement specifies the placement of OLM catalog components. By default, this is set to management and OLM catalog components are deployed onto the management cluster. If set to guest, the OLM catalog components will be deployed onto the guest cluster.
