Chapter 2. Containerized services

Procedure

1. Create a new container images file for your overcloud:

   $ sudo openstack tripleo container image prepare default \
       --local-push-destination \
       --output-env-file containers-prepare-parameter-dellemc.yaml

2. Edit the containers-prepare-parameter-dellemc.yaml file.

3. Add an exclude parameter to the strategy for the main Red Hat OpenStack Platform container images. Use this parameter to exclude the container image that the vendor container image will replace. In the example, the container image is the cinder-volume image:

   parameter_defaults:
     ContainerImagePrepare:
       - push_destination: true
         excludes:
     	   - cinder-volume
         set:
           namespace: registry.redhat.io/rhosp-rhel9
           name_prefix: openstack-
           name_suffix: ''
           tag: 16.2
           ...
         tag_from_label: "{version}-{release}"

4. Add a new strategy to the ContainerImagePrepare parameter that includes the replacement container image for the vendor plugin:

   parameter_defaults:
     ContainerImagePrepare:
       ...
       - push_destination: true
         includes:
           - cinder-volume
         set:
           namespace: registry.connect.redhat.com/dellemc
           name_prefix: openstack-
           name_suffix: -dellemc-rhosp16
           tag: 16.2-2
           ...

5. Add the authentication details for the registry.connect.redhat.com registry to the ContainerImageRegistryCredentials parameter:

   parameter_defaults:
     ContainerImageRegistryCredentials:
       registry.redhat.io:
         [service account username]: [service account password]
       registry.connect.redhat.com:
         [service account username]: [service account password]

6. Save the containers-prepare-parameter-dellemc.yaml file.

7. Include the containers-prepare-parameter-dellemc.yaml file with any deployment commands, such as as openstack overcloud deploy:

   $ openstack overcloud deploy --templates
       ...
       -e containers-prepare-parameter-dellemc.yaml
       ...

   When director deploys the overcloud, the overcloud uses the vendor container image instead of the standard container image.

   IMPORTANT

   The containers-prepare-parameter-dellemc.yaml file replaces the standard containers-prepare-parameter.yaml file in your overcloud deployment. Do not include the standard containers-prepare-parameter.yaml file in your overcloud deployment. Retain the standard containers-prepare-parameter.yaml file for your undercloud installation and updates.
