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.
