I moved the mmr server to alpine linux! Before, it was regular raspberry pi os lite on the Pi. But, it was behaving strangely, randomly rebooting and things, so I decided to try installing Alpine. The lightweight distro has been on my radar for a while now, but this was my first time ever actually trying it.

I imaged it normally with the raspberry pi imager, and put it on the pi, did setup-alpine, and all was well. But, I put in the wrong wifi password at first, which broke everything else. I tried changing the wifi config and doing something with wpa_supplicant (thanks google ai overview), but nothing fixed it so I ended up doing a fresh install.

This time, I put in the right password and everything went great. I set up ssh, node, pm2, etc. and moved the server files onto the pi through sftp. Then, I got it running over my local network and set up authentication.

So, it was time to set up the Cloudflare tunnel again. I followed this neat guide, changing values as needed (for example, my pi is aarch64, but the guide was x64, so I spent a while figuring out why the pi kept giving elf errors). It took a really long time to set up the openrc startup script because 1. cloudflare rotates the setup token relatively frequently and 2. I accidentally put 2 –token arguments. And since I was using vi, I didn’t even notice and kept trying to figure out why cloudflared crashed on startup. But I eventually found out and removed the duplicate and it worked!

Then I finished setting up pm2 and put the pi in its home next to the router, and mmr.kmdw.dev is back up exposing your lobby’s skills. See you in the next one!

Yes I know part of the token is in the image but it’s used already so it doesn’t matter
