===========================================================================
|
|
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.
