Building a Private Docker Registry

1. Create an htpasswd file containing the login credentials for the initial account.
2. Create a self-signed certificate for the registry. For the common name, enter the hostname of the registry server, which is ip-10-0-1-101.
3. Create a container to run the registry.
4. Once the registry starts up, verify that it is responsive. It's OK if this command returns nothing, just make sure it does not fail.

Note: A private Docker registry is running on the Docker registry server using version 2.7 of the registry image.

1. Get the public hostname from the registry server. It should be ip-10-0-1-101.
2. Add the registry's public self-signed certificate to /etc/docker/certs.d. The scp command is copying the file from the registry server to the workstation. The password is the normal cloud_user password provided by the lab.
3. Log in to the private registry from the workstation. The credentials should be username docker and password d0ck3rrU73z.
4. Test the registry by pushing an image to it. You can pull any image from the Docker hub and tag it appropriately to push it to the registry as a test image.
5. Verify image pulling by deleting the image locally and re-pulling it from the private repository.
