Recently I’ve been playing with containers a little bit in my lab. Today I’m going to show you how to get a Docker engine running on a CentOS 7 VM running on an ESXi host. It’s surprisingly easy!
First, what is Docker? It’s an engine that lays on top of an existing host OS and basically removes the “Guest OS” abstraction layer from the mix. This is good because the Guest OS is a big resource hog when you start having several of them per host.

So what does this mean? Is this (potentially) bad news for VMware and Microsoft?
Short answer: yes.
Long answer: Yeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeesssssssssssssssssssssssssssssssssssssssssssss*
*VMware and MS are working on projects to get in on the containery goodness, so I won’t speak about that here. Instead I’m going to walk through how to set up your first Docker engine ON CentOS ON ESXi in your existing vSphere environment.
