make sure to download and install docker using these instructions and do not use OS repo's cuz those don't always work correctly https://docs.docker.com/engine/installation/linux
to run this just use the command "sudo docker-compose up"
then go to a browser and type localhost:8080 and any webpages placed in www folder should be accessable
Based off of https://github.com/devigner/docker-compose-php with the attempt to run the minimal versions (alpine) when avalible.
