Continuous Delivery with Docker and Jenkins

Installing the Docker registry application

Docker registry is available as a Docker image. To start this, we can run the following command:

$ docker run -d -p 5000:5000 --restart=always --name registry registry:2

By default, the registry data is stored as a docker volume in the default host filesystem's directory. To change it, you can add -v <host_directory>:/var/lib/registry. Another alternative is to use a volume container.

The command starts the registry and makes it accessible via port 5000. The registry container is started from the registry image (version 2). The --restart=always option causes the container to automatically restart whenever it's down.

Consider setting up a load balancer and starting a few Docker registry containers ...
