Chapter 3. Retrieving the container images

Procedure

1. Add your Registry Service Account credentials to containers.yaml.

   parameter_defaults:
     NeutronMechanismDrivers: ovn
     ContainerImagePrepare:
     - push_destination: 192.168.24.1:8787
       set:
         ceph_namespace: registry.redhat.io/rhceph
         ceph_image: rhceph-4-rhel8
         ceph_tag: latest
         name_prefix: openstack-
         namespace: registry.redhat.io/rhosp16-rhel8
         tag: latest
     ContainerImageRegistryCredentials:
       # https://access.redhat.com/RegistryAuthentication
       registry.redhat.io:
         registry-service-account-username: registry-service-account-password

2. Generate the environment file as ~/containers-env-file.yaml:

   $ openstack tripleo container image prepare -e containers.yaml --output-env-file ~/containers-env-file.yaml

   In Deploying the central controllers and Deploying HCI nodes to the distributed compute node (DCN) site, the resulting ~/containers-env-file.yaml file is included as part of the overcloud deployment procedure.
