Dockerized octodown

⚠️ This dockerize has been incomplete yet for needing launchy.

$ docker pull masutaka/octodown
$ mkdir -p ~/bin && cd $_
$ curl -LO https://raw.githubusercontent.com/masutaka/docker-octodown/master/bin/octodown
$ chmod +x octodown
$ export PATH=$HOME/bin:$PATH

See https://github.com/ianks/octodown

The following features are not supported for the docker limitation.

• LiveReload
  • I exported $TEST in Docker container. But...
• STDIN
  • I might be able to support it.
