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.
On the System Controller, get the password for the
$ keyring get sysinv services
On each subcloud, run the following script to update the Docker registry credentials to
$ update_docker_registry_auth.sh sysinv <sysinv_password>
