Hi there!

Some days ago I started learning Discourse and didn’t find a Dockerfile for Apple/M chips. So I had created my own and I would like to share it with anyone who also wants keep a control over own image.

Also by this post I would like to learn how Discourse and community work. I hope you find my post helpful. You are welcome to provide any feedback/thoughts/questions about my Dockerfile.

My Dockerfile is for Apple/M chips, but can be easily modified
