Five-step setup for private Docker repository with Let's Encrypt SSL

Make sure you have a domain name and SSH access to an instance. This works well under a DigitalOcean's Ubuntu with Docker and Docker Compose installed.

Steps

  1. Set in docker-compose.yml the REGISTRY_USER, REGISTRY_PASSWORD and DOMAIN on the Nginx args.
  2. On ssl_gen set DOMAIN value with your domain.
  3. docker-compose up -d
  4. chmod +x *.sh && ./ssl_gen.sh
  5. After it succeeds, start it with docker-compose restart

After it succeeds

  1. docker login my-repo-url.com give your user name/pass
  2. It should say Login Succeeded

Automatic cron setup

This will schedule a renewal of the SSL cert with Let's Encrypt every 15 days.

  1. crontab -u $USER -e
  2. 0 0 */15 * * /path/to/registry_files/ssl_renew.sh
