OpenShift SSH Public Key

This parameter stores the public portion of the SSH key pair used for secure access to OpenShift cluster nodes. This key is automatically generated during cluster deployment.

Requirements

• Must be a valid ED25519 SSH public key
• Must correspond to private key in openshift/ssh-key
• Must be in standard OpenSSH public key format

Usage

The key is automatically generated during the openshift-cluster-tools task:

# Generated using
ssh-keygen -t ed25519 -N '' -f /root/.ssh/cluster_ssh_key

# Format example
ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAI... root@helper

Notes: - Public key is safe to share and distribute - Key is automatically stored in profile during generation - Used in install-config.yaml for node configuration - Added to authorized_keys on all cluster nodes
