Development environment w/ devcontainer on M1 (arm) Mac?

Development
1

I’m rather new to Home Assistant, hoping to develop some custom integrations. Following instructions to set up a development environment on my M1 Mac, I found that the containerized environment was super-laggy and unstable (crashing the emulated Linux kernal, etc.). It seems likely that this is because it’s an x86 container and running under qemu. I haven’t the first idea where to look to see if I can force it to use an arm64 container. Has anybody else figured this out?

I just tried arm64 builds on the M1 using Ubuntu running under Parallels (super fast) and then on a RPi4 running Ubuntu (not so fast) and both fail, I looked here to see if you need to use an x86 to get this done and am guessing it might be the case.

My first time to try this as I was asked to help test a new integration, maybe time to dust off an old Intel iMac to see if I can get past this.

I had the same question so I figured out how to do this today when I couldn’t find any information on it: Here is my repo of Addons that has a .devcontainer built for m1 Apple Silicon Macs. Enjoy.
