When mirroring a repository from an external container registry, you must create a new private repository. Typically, the same name is used as the target repository, for example, quay-rhel8.
Use the following procedure to adjust the settings of your mirrored repository.
-
You have enabled repository mirroring in your {productname} configuration file.
-
You have deployed a mirroring worker.
-
In the Settings tab, set the Repository State to

In the Mirror tab, enter the details for connecting to the external registry, along with the tags, scheduling and access information:

-
Start Date: The date on which mirroring begins. The current date and time is used by default.

HTTPS PROXY: Identify the HTTPS proxy server needed to access the remote site, if a proxy server is needed.
