Unofficial docker build of the regexr node app. Uses ubuntu:latest docker image. I know this probably can be done more efficiently but I couldn't get gufertum or winkelchri docker images to work.
* Edit first four lines variables.
make build - Builds container using Dockerfile
make run - Creates temp container - removes when exited.
make sh - open shell command on configured container
make bash - open bash command on configured container
make removeall - remove configured container and image
make tag - tag :latest to image
