petergrace/octodocker repository overview

(If you want to see the dockerfile, the project is here: https://github.com/petergrace/octodocker⁠) -- docker hub cannot build arm images so I had to push it manually rather than use an automated build

This is an ARM-based alpine image with python, OctoPrint and OctoPrint's requirements.

I made this so I could run multiple octoprints on the same raspberry pi with operational separation, and I thought making a docker image was cool.

I use docker-compose to start it, here's my example docker-compose.yml, which starts octoprint and mounts two folders for my custom home directory for the printer, and mounts a shared uploads directory that all of my octoprint instances share. Change OCTOPORT to whatever port you want the octoprint instance to listen on, and change the ports: declaration as well.
