Prepare the IBM Z® environment

Prerequisites

• You have a Red Hat® OpenShift® cluster installed.
• You have the Red Hat OpenShift Virtualization Operator installed.
• You have access to the Red Hat OpenShift cluster as a user with `cluster-admin` privileges.
• You have sufficient storage available.
  Note: For production environments, Red Hat OpenShift Data Foundation is recommended.
• You have a second network interface card (NIC) available for Linux® bridging, if required.

Create a secret

1. Create a secret with the public key by running the following command:

   oc create secret generic my-public-key-secret \
     --from-literal=publickey=<secret_key>"
   

   Note: For production environments, consider security policies for encryption.
2. Alternatively, you can create the secret by using a YAML file.
   1. Convert your public key into Base64 by running the following command:

      cat id_rsa.pub | base64 -w0

   2. Create a secret.yaml with the generated key, similar to the following:

      apiVersion: v1
      kind: Secret
      metadata:
        name: my-public-key-secret
      type: Opaque
      data:
        publickey: <BASE64_ENCODED_PUBLIC_KEY>

   3. Create the secret from the secret.yaml file by running the following command:

      oc apply -f secret.yaml

A secret is created in the current active namespace so that the specified public key gets injected to the VM during cloud-init. The VM can now be accessed externally.
