OpenStack Client Docker Container

May 26, 2017

OpenStack has been my world for the past 8 months. It started out with the a work project to design and deploy a large-scale VMware Integrated OpenStack environment for internal use.

There are a few projects like Flocker […]

Docker Minecraft Containers to the Rescue!

My 11-year old son has been after me to get a Minecraft server setup locally that he could connect to and play off of any of the computers in the house. Fortunately for him, my home lab environment is running a few different Docker container hosts, and I figured loading up a couple servers via […]
