Issue

  • How to create Internal docker registry on Red Hat Satellite 6 using SSL and Non-SSL methods?

Resolution

  • Create Docker Product, Docker Repository on Red Hat Satellite 6

    • Create Custom Product and Custom Repository with type as 'docker'

    • Sync docker images from Upstream registry ie- 'registry.access.redhat.com' OR 'https://registry-1.docker.io'

    • This would show Published At URL like 'satellite.example.com:5000/default_organization-docker_product-docker_repo'.
      where satellite.example.com = Satellite Server HostName , default_organization = Organization Name, docker_product = Product Name, docker_repo = Repository Name

    • Once sync is done, Click on Manager Docker Manifests or Manage Docker Images and note the Tag ID.
      Eg:- 6.7-32

  • Building Custom Images using Red Hat Satellite 6 as Docker Registry Server

    • Install docker packages on Red Hat Satellite Server available in rhel-7-server-extras-rpms

    • On Satellite cli, create Dockerfile under any directory and write the sample code as below:-

      # vi Dockerfile
FROM localhost:5000/default_organization-docker_product-docker_repo:6.7-32
RUN touch /usr/local/bin/hello
RUN echo "Hi, Welcome to Docker, World !!!" >> /usr/local/bin/hello
RUN chmod 777 /usr/local/bin/hello

      # docker build -t <IMAGE NAME> .           >>>>>>        Note:- build must be performed where Dockerfile is written.
# docker images

  • On Docker Client.

    # mkdir -p /etc/docker/certs.d/<Satellite registry Server Name>:5000
# scp root@satellite.example.com:/etc/pki/tls/certs/self.crt /etc/docker/certs.d/docker.example.com\:5000/ca.crt   >>>> docker.example.com is RHEL docker client and satellite.example.com is Red Hat Satellite Registry Server.
# systemctl restart docker.

  • On Docker Client, test SSL Registry.

    # docker pull satellite.example.com:5000/<IMAGE>:<TAG ID>
