Unofficial docker build of the regexr node app. This is simply done, because running node apps on ubuntu is a pain in the ass. A dockerized app is nice and clean and you can easily spin it up and serve it behind a proxy.
This image is based on mhart/alpine-node, a minimal Node.js image based on Alpine Linux.
make
The image can be retrieved from the docker hub.
