When installing Docker Trusted Registry it's possible to create an admin user that does not have admin rights. This will prevent you from logging into the admin web interface. You can recover from this by running a special recovery container.
You can't log into your DTR web interface.
Point your browser to http://
Try logging in with the user you created during installation.
Access is denied.
However, you can confirm that the DTR admin container is still running by executing the following command on the DTR host:
You should see output similar to the following with the status for
trusted-registrycontainers showing that they are up and running:

To solve this problem, log into the DTR admin web interface using an ambassador container, create an admin user with admin rights, and then stop the ambassador container.
Make sure you are logged into the host that is running the DTR admin container.
Make sure you are logged in as a user that's a member of the
dockergroup, or have root privileges. Otherwise, you may have to add the prefix
docker runcommand below.
You can run an ambassador container to get temporary, insecure access to your DTR instance by executing the following command:
docker run --rm -it --link docker_trusted_registry_admin_server:admin -p 9999:80 svendowideit/ambassador
This will give you access on port 9999 to your DTR instance:
Make sure you stop the ambassador container once you've given your user correct permissions.
