Creating an InfraEnv resource for hosted control planes on IBM Power

An InfraEnv resource is an environment where hosts that are starting the live ISO can join as agents. In this case, the agents are created in the same namespace as your hosted control plane.

You can create an InfraEnv resource for hosted control planes on 64-bit x86 bare metal for IBM Power compute nodes.

Procedure

Create a YAML file to configure an InfraEnv resource. See the following example:
```
apiVersion: agent-install.openshift.io/v1beta1
kind: InfraEnv
metadata:
  name: <hosted_cluster_name>
  namespace: <hosted_control_plane_namespace>
spec:
  cpuArchitecture: ppc64le
  pullSecretRef:
    name: pull-secret
  sshAuthorizedKey: <path_to_ssh_public_key>
```
- metadata.name specifies the name of your hosted cluster.
- metadata.namespace specifies the name of the hosted control plane namespace, for example, clusters-hosted.
- spec.sshAuthorizedKey specifies the path to your SSH public key. The default file path is ~/.ssh/id_rsa.pub.
Save the file as infraenv-config.yaml.
Apply the configuration by entering the following command:
```
$ oc apply -f infraenv-config.yaml
```
To fetch the URL to download the live ISO, which allows IBM Power machines to join as agents, enter the following command:
```
$ oc -n <hosted_control_plane_namespace> get InfraEnv <hosted_cluster_name> \
  -o json
```
