Switching from Vagrant to Docker

I've been experimenting with Docker as an alternative to Vagrant (and VVV) for WordPress development.

I had looked into Docker in the past, but given how easy Vagrant and VVV were, I was in no hurry to switch. VVV still is awesome (there is an excellent getting started guide here), but since settling on Vagrant, the tools and ecosystem around Docker have significantly improved.

Mainly to satisfy my own curiosity, but also hoping to use less system resources (since I currently code on a Macbook Air) I finally gave Docker a fair chance. I wanted to share some of the things I’ve learned over the past week whilst switching.

Rather than use a library, we were really keen to use native range inputs to keep our dependencies to a minimum, and so the range inputs were semantic and keyboard accessible. Our idea was to overlay 2 range sliders to form a single component. I’d like to share some of my findings.

Being a huge fan of video games (and retro style graphics!) logically I chose a Super Mario theme for the room and set about making plans to create a large wall mural and other themed objects (as well as doing the boring adult stuff like flooring and painting the walls).
