Update Credentials Used by Subcloud for Install Registry (registry.central)¶
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.
Warning
If the following registry information/credentials are changed, a new subcloud backup must be taken to avoid having a backup that contains old registry credentials.
Use the following procedure to update credentials used by the Subcloud to access
its install registry (registry.central) to the sysinv
service credentials of
the System Controller.
Procedure
On the System Controller, get the password for the
sysinv
services.$ keyring get sysinv services
On each subcloud, run the following script to update the Docker registry credentials to
sysinv
:$ update_docker_registry_auth.sh sysinv <sysinv_password>
