A Practical Introduction to the Docker Registry Server

Background One of the key advantages of using Docker is it’s centralized image management server, called a Registry Server. The Docker project, as well as Red Hat, maintain public registry servers which host supported images. The Docker project also provides an Open Source version of the Registry server which can be deployed on premise in

A Practical Introduction to Docker Containers

Background Why Docker has quite an amount of buzz around it today because it makes so many things easy that were difficult with virtual machines.

This allows a Linux desktop or server to simulate multiple pieces of hardware, which can then have different operating systems installed. KVM uses the QEMU virtual machine format. QEMU may be familiar to those

Bootstrapping and Rooting Documentation: Part 2

Background In Bootstrapping and Rooting Documentation: Part 1, I laid out a blueprint for using documentation as the bootstrap for entry into an operations environment.
