Previously I moved my jekyll installation inside a Vagrant image. At the time this was a big improvement over installing and maintaining ruby/jekyll locally on my machines.
For a while now I have wanted to move this installation inside Docker instead. I actually use Docker daily in my work and am very comfortable in that environment.
It wasn't until the recent release of Docker for Mac beta that this became practical though with the improvements to volume mapping.
So this morning I finally made the switch.
