Docker Registry Configure

From JFrog:

• A Docker repository is a hosted collection of tagged images that, together, create the file system for a container
• A Docker registry is a host that stores Docker repositories
• An Artifactory repository is a hosted collection of Docker repositories, effectively, a Docker registry in every way, and one that you can access transparently with the Docker client.

If you change the setting in docker registry running container, try

docker restart <container id>
