9.6.2.3. Dynamic key management


You can enable dynamic key injection for a virtual machine (VM) by using the OpenShift Container Platform web console or the command line. Then, you can update the key at runtime.

참고

Only Red Hat Enterprise Linux (RHEL) 9 supports dynamic key injection.

If you disable dynamic key injection, the VM inherits the key management method of the image from which it was created.

9.6.2.3.1. Enabling dynamic key injection when creating a VM from a template

You can enable dynamic public SSH key injection when you create a virtual machine (VM) from a template by using the OpenShift Container Platform web console. Then, you can update the key at runtime.

참고

Only Red Hat Enterprise Linux (RHEL) 9 supports dynamic key injection.

The key is added to the VM by the QEMU guest agent, which is installed with RHEL 9.

Prerequisites

  • You generated an SSH key pair by running the ssh-keygen command.

Procedure

  1. Navigate to Virtualization Catalog in the web console.
  2. Click the Red Hat Enterprise Linux 9 VM tile.
  3. Click Customize VirtualMachine.
  4. Click Next.
  5. Click the Scripts tab.
  6. If you have not already added a public SSH key to your project, click the edit icon beside Authorized SSH key and select one of the following options:

    • Use existing: Select a secret from the secrets list.
    • Add new:

      1. Browse to the SSH key file or paste the file in the key field.
      2. Enter the secret name.
      3. Optional: Select Automatically apply this key to any new VirtualMachine you create in this project.
  7. Set Dynamic SSH key injection to on.
  8. Click Save.
  9. Click Create VirtualMachine.

    The VirtualMachine details page displays the progress of the VM creation.

Verification

  • Click the Scripts tab on the Configuration tab.

    The secret name is displayed in the Authorized SSH key section.
