Update Docker Registry Credentials on a Subcloud

On a subcloud that uses the System Controller’s Docker registry (registry.central) as its install registry, you should use the System Controller’s sysinv service credentials for accessing registry.central. This makes access to registry.central independent of changes to the Distributed Cloud’s Keystone admin user password.

Use the following procedure to update the install registry credentials on the subcloud to the sysinv service credentials of the System Controller.

Procedure

1. On the System Controller, get the password for the sysinv services.

   $ keyring get sysinv services
   

2. On each subcloud, run the following script to update the Docker registry credentials to sysinv:

   $ update_docker_registry_auth.sh sysinv <sysinv_password>
