Running alternative versions branches in a Docker container

4. Running different versions within a docker container =======================================================

   • checkout the version you want from git to a folder

   • from there you run

     $ docker build -t "image_name" -f dockerize/Dockerfile .

   • checkout the dockerize repository (link see below)

   • change the "b2share" container's image line in the docker-compose.yml file. Example:

     image: eudatb2share/b2share:2.0.1

   to

    `build: image_name`
   

   where "image_name" is the string that you provided in the docker build command above. Now you can run docker-compose up from that directory.
