1. I first tried to install this on my Win10 VM, which needed to have Docker installed. That was a terrible idea. I completely broke my VM as Docker tried to enable Hyper-V. Friends don't let friends attempt nested virtualization. I should have just run the container on the host instead, which it supports quite well.
2. The repo worked as the blog post described on my mac. Its quick and has been able to run some tricky extensions. I need to experiment with running some external dependancies still.
3. Docker commit worked nicely, making a layer for the changes I made. Still playing with this, but wow that could be very productive if it enabled me to roll back to a tested base environment, or share a full IDE image with somebody on my team.
