Chapter 4. Updating Image Mode (bootc) data plane nodes

Procedure

1. Update OVN services as described in Updating OVN services on the data plane.
2. Update the remaining data plane services as described in Updating the remaining services on the data plane.
3. Build and deploy the updated Image Mode container image as described in Building the Image Mode (bootc) container image in Customizing the Red Hat OpenStack Services on OpenShift deployment.

4. Create an OpenStackDataPlaneDeployment CR to deploy the updated container image. The following is an example configuration:

   apiVersion: dataplane.openstack.org/v1beta1
   kind: OpenStackDataPlaneDeployment
   metadata:
     name: edpm-compute-bootc-update
   spec:
     nodeSets:
       - edpm-compute-bootc
     servicesOverride:
       - update
       - reboot
     ansibleVars:
       edpm_update_system_bootc_os_container_image: "<container_image_url>"

   • Replace <container_image_url> with the full URL to the updated container image.
5. Save the OpenStackDataPlaneDeployment CR file.

6. Apply the OpenStackDataPlaneDeployment CR to your environment.

   $ oc apply -f <deployment_cr_file>

   • Replace <deployment_cr_file> with the name of the OpenStackDataPlaneDeployment CR file.
7. Verify the update completes successfully.

Procedure

1. Verify if a new version of openstack-selinux is available in your repositories.

2. If a new version of openstack-selinux is available, perform the following tasks:

   1. Build and deploy the updated container image as described in Building the Image Mode (bootc) container image in Customizing the Red Hat OpenStack Services on OpenShift deployment.

   2. Create an OpenStackDataPlaneDeployment CR to deploy the updated container image. The following is an example configuration:

      apiVersion: dataplane.openstack.org/v1beta1
      kind: OpenStackDataPlaneDeployment
      metadata:
        name: edpm-update-system-selinux
      spec:
        nodeSets:
          - edpm-compute-bootc
        servicesOverride:
          - update-system
          - reboot
        ansibleVars:
          edpm_update_system_bootc_os_container_image: "<container_image_url>"

      • Replace <container_image_url> with the full URL to the updated container image.
   3. Save the OpenStackDataPlaneDeployment CR file.

   4. Apply the OpenStackDataPlaneDeployment CR to your environment.

      $ oc apply -f <deployment_cr_file>

      • Replace <deployment_cr_file> with the name of the OpenStackDataPlaneDeployment CR file.

   5. Create an OpenStackDataPlaneDeployment CR to update the data plane services. The following is an example configuration:

      apiVersion: dataplane.openstack.org/v1beta1
      kind: OpenStackDataPlaneDeployment
      metadata:
        name: edpm-update-services-bootc
      spec:
        nodeSets:
          - edpm-compute-bootc
        servicesOverride:
          - update-services

   6. Save the OpenStackDataPlaneDeployment CR file.

   7. Apply the OpenStackDataPlaneDeployment CR to your environment.

      $ oc apply -f <deployment_cr_file>

      • Replace <deployment_cr_file> with the name of the OpenStackDataPlaneDeployment CR file.
3. Build and deploy the updated Image Mode container image as described in Building the Image Mode (bootc) container image in Customizing the Red Hat OpenStack Services on OpenShift deployment.

4. Create an OpenStackDataPlaneDeployment CR to deploy the updated Image Mode container image. The following is an example configuration:

   apiVersion: dataplane.openstack.org/v1beta1
   kind: OpenStackDataPlaneDeployment
   metadata:
     name: edpm-update-bootc
   spec:
     nodeSets:
       - edpm-compute-bootc
     servicesOverride:
       - update-system
       - reboot
     ansibleVars:
       # Specify the new bootc image to switch to
       edpm_update_system_bootc_os_container_image: "<container_image_url>"

   • Replace <container_image_url> with the full URL to the updated container image.
5. Save the OpenStackDataPlaneDeployment CR file.

6. Apply the OpenStackDataPlaneDeployment CR to your environment.

   $ oc apply -f <deployment_cr_file>

   • Replace <deployment_cr_file> with the name of the OpenStackDataPlaneDeployment CR file.
7. Verify the update completes successfully.
