Descriptions

view-private-registry is a bash script for listing images in a private registry v2. It does not require registry v2 to be running on the system, only the filesystem where the images are stored. Docker search registry v2 functionality is currently not supported at the time of this writing. See discussion since Feb 2015: "propose registry search functionality #206" distribution/distribution#206

view-private-registry-remote is a bash script for listing images in a private registry v2 from a remote system that does not have the NFS filesystem mounted where the images are stored. This script requires ssh to be installed and configured on the systems required to run this script. This script calls the view-private-registry script that is on the host with the NFS filesystem mounted.

Install

To Install, change into a directory that you want to download the scripts. Use git to pull or clone these scripts into the directory. If you do not have Git installed then enter; "sudo apt-get install git" if using Debian/Ubuntu. Other Linux distribution install methods can be found here: https://git-scm.com/download/linux. On the GitHub page of this script use the "HTTPS clone URL" with the 'git clone' command.

git clone https://github.com/BradleyA/Search-docker-registry-v2-script
cd Search-docker-registry-v2-script

Edit view-private-registry script, change PERSISTENT_REGISTRY_STORAGE_FILESYSTEM_ROOTDIRECTORY to the path to your registry storage filesystem root directry. It is the volume you used when starting the registry for /var/lib/registry.

 PERSISTENT_REGISTRY_STORAGE_FILESYSTEM_ROOTDIRECTORY="<your registry storage filesystem root directry>"

Move the script or create a symbolic link to a location in your working path; example /usr/local/bin. To find directories in your working path use; "echo $PATH".

cp view-private-registry ..
cd ..
sudo ln -s $PWD/view-private-registry /usr/local/bin/view-private-registry

Edit view-private-registry-remote script, change REMOTE_REGISTRY_HOST to the remote host that has the registry v2 mounted, change REMOTE_ADMIN_ACCOUNT to the ssh admin account on the REMOTE_REGISTRY_HOST.

 REMOTE_REGISTRY_HOST="<server IP address or FQDN>"
 REMOTE_ADMIN_ACCOUNT="<ssh admin account for the above host>"

Move the script or create a symbolic link to a location in your working path (see example above).

TLS

I wrote a few scripts that may help you with the private registry and TLS. The scripts are create-registry-tls.sh, copy-registry-tls.sh, and check-registry-tls.sh which can be found in https://github.com/BradleyA/docker-security-infrastructure/blob/master/docker-TLS/README.md. These scripts support --help and --usage options to reduce the learning curve.
