Support Docker

[parrt]

Support Docker (Fixes #21):

$ cd antlr4-lab
$ mvn clean package  # has to be built first as docker copies in the jar
$ docker build --tag antlr4-lab-docker .
$ docker run -p80:80 --rm antlr4-lab-docker

Then just open browser to http://localhost/index.html

Heh @kaby76, are you one with Docker? Can you check this out? @teverett?

[kaby76]

I can check later today. I have to reinstall docker....it doesn't be quiet, asks all the time "Can I update?", like displaying advertisements.

Seems to work fine. But I had to do some things to get it to work on Windows/WSL2.

• In Windows:
  • Install Docker Desktop
• In WSL2/ Ubuntu:
  • sudo apt install docker.io
  • git clone https://github.com/antlr/antlr4-lab.git
  • cd antlr4-lab
  • git checkout docker
  • mvn clean; mvn install
  • docker build .
  • docker image ls # get image name.
  • docker run -d -p 127.0.0.1:80:80 -e BIND_ADDR=0.0.0.0:80 image-name-from-above
• In Windows again, run Firefox and connect to 127.0.0.1

It looks like docker binds port 80 to 0.0.0.0 by default (after installing net-tools, and doing netstat -a).

Thanks! Yeah, not sure it's useful but I'll merge in case people want. I'll add your comments to info.
