Chapter 2. Preparing for overcloud deployment with the director Operator

Procedure

1. The default QCOW2 image that you have downloaded from access.redhat.com does not use biosdev predictable network interface names. Modify the image with virt-customize to use biosdev predictable network interface names:

   $ sudo virt-customize -a <local path to image> --run-command 'sed -i -e "s/^\(kernelopts=.*\)net.ifnames=0 \(.*\)/\1\2/" /boot/grub2/grubenv'
   $ sudo virt-customize -a <local path to image> --run-command 'sed -i -e "s/^\(GRUB_CMDLINE_LINUX=.*\)net.ifnames=0 \(.*\)/\1\2/" /etc/default/grub' --truncate /etc/machine-id

2. Upload the image to OpenShift Virtualization with virtctl:

   $ virtctl image-upload dv <datavolume_name> -n openstack \
    --size=<size> --image-path=<local_path_to_image> \
    --storage-class <storage_class> --access-mode <access_mode> --insecure

   • Replace <datavolume_name> with the name of the data volume, for example, openstack-base-img.
   • Replace <size> with the size of the data volume required for your environment, for example, 500Gi. The minimum size is 500GB.

   • Replace <storage_class> with the required storage class from your cluster. Use the following command to retrieve the available storage classes:

     $ oc get storageclass

   • Replace <access_mode> with the access mode for the PVC. The default value is ReadWriteOnce.

3. When you create the OpenStackControlPlane resource and individual OpenStackVmSet resources, set the baseImageVolumeName parameter to the data volume name:

   ...
   spec:
     ...
     baseImageVolumeName: openstack-base-img
   ...

Procedure

1. Create the Secret resource:

   $ oc create secret generic git-secret -n openstack --from-file=git_ssh_identity=<path_to_private_SSH_key> --from-literal=git_url=<git_server_URL>

   The git-secret Secret resource contains two key-value pairs:

   git_ssh_identity

   The private key to access the Git repository. The --from-file option stores the content of the private SSH key file.

   git_url

   The SSH URL of the git repository to store the configuration. The --from-literal option stores the URL that you enter for this key.

Verification

1. View the Secret resource:

   $ oc get secret/git-secret -n openstack

Procedure

1. Convert your chosen password to a base64 value:

   $ echo -n "p@ssw0rd!" | base64
   cEBzc3cwcmQh

   Note

   The -n option removes the trailing newline from the echo output.

2. Create a file named openstack-userpassword.yaml on your workstation. Include the following resource specification for the Secret in the file:

   apiVersion: v1
   kind: Secret
   metadata:
     name: userpassword
     namespace: openstack
   data:
     NodeRootPassword: "cEBzc3cwcmQh"

   Set the NodeRootPassword parameter to your base64 encoded password.

3. Create the userpassword Secret:

   $ oc create -f openstack-userpassword.yaml -n openstack
