Continuous Delivery with Docker and Jenkins

Adding a domain certificate

If the registry is run on the localhost, then everything works fine and no other installation steps are required. However, in most cases, we want to have a dedicated server for the registry, so that the images are widely available. In that case, Docker requires securing the registry with SSL/TLS. The process is very similar to the public web server configuration and, similarly, it's highly recommended having the certificate signed by CA (certificate authority). If obtaining the CA-signed certificate is not an option, then we can self-sign a certificate or use the --insecure-registry flag.
