Docker resources to run Retropie Install script as a container, and game using Retropie on Linux without the need of dual-boot
Note that it is implicit that you might need to have docker daemon already running, or any additional software that is capable of handling docker images like podman(podman-docker might also be handy to help with cli syntax)
Install the xhost command on your desktop as well.
git clone --depth=1 https://github.com/nwildner/retropie-docker.git
cd retropie-docker
docker build -t retropie-docker .
This will build an image that is currently based on Ubuntu LTS 20.04 from official docker images because, this is a requisite for Retropie. Needs further testing if this could be done with a Debian image as well.
Ubuntu 22.04 is not supported due to an SDL2 bug that is making retroarch autoconfiguraton steps break.
Take a look at the cmd.sh file from this repo, and change the directories to one that will better reflect the location you want to keep your Roms, BIOS, User local EmulationStation dir (es_homedir_config), Global Emulationstation config (es_config) and Retroarch autogenerated controler files(retroarch_autoconfig).
These are pretty much the places you need to keep on your home directory after kill out your container.
To run:
$ chmod +x cmd.sh
$ ./cmd.sh
If you have first started EmulationStation, it will clean-up all controller config data as per entrypoint.sh. After that, EmulationStation will be launched. cmd.sh script will also set the permissions for the docker process to access X with the xhost utility.
So far, you'll have to map your local paths inside cmd.sh while we develop something like a config file.
