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
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>
