= Versioning for hosted control planes
|
|
|
|
With each major, minor, or patch version release of {product-title}, two components of hosted control planes are released:
|
|
|
|
* HyperShift Operator
|
|
* Command-line interface (CLI)
|
|
|
|
The HyperShift Operator manages the lifecycle of hosted clusters that are represented by `HostedCluster` API resources. The HyperShift Operator is released with each {product-title} release. After the HyperShift Operator is installed, it creates a config map called `supported-versions` in the HyperShift namespace, as shown in the following example. The config map describes the HostedCluster versions that can be deployed.

|
|
[source,yaml]
|
|
----
|
|
apiVersion: v1
|
|
data:
|
|
supported-versions: '{"versions":["4.13","4.12","4.11"]}'
|
|
kind: ConfigMap
|
|
metadata:
|
|
labels:
|
|
hypershift.openshift.io/supported-versions: "true"
|
|
name: supported-versions
|
|
namespace: hypershift
|
|
----
|
|
|
|
The CLI is a helper utility for development purposes. The CLI is released as part of any HyperShift Operator release. No compatibility policies are guaranteed.
|
|
|
|
The API, `hypershift.openshift.io`, provides a way to create and manage lightweight, flexible, heterogeneous {product-title} clusters at scale. The API exposes two user-facing resources: `HostedCluster` and `NodePool`. A `HostedCluster` resource encapsulates the control plane and common data plane configuration. When you create a `HostedCluster` resource, you have a fully functional control plane with no attached nodes. A `NodePool` resource is a scalable set of worker nodes that is attached to a `HostedCluster` resource.

|
|
The API version policy generally aligns with the policy for link:https://kubernetes.io/docs/reference/using-api/#api-versioning[Kubernetes API versioning].
