Introduction
Our previous chapters have done a lot of work already with Docker images. As you've seen, we've been able to take existing images, provided to the general public in Docker Hub, and have then been able to run them or reuse them after building on top of them for our purposes. The image itself helps us streamline our processes and reduce the work we need to do.
