Docker

I’ve got a mix of architectures in my basement cluster - some Odroid HC2s that are arm7, some Raspberry Pi 4s that are arm64, and am soon going to add an Intel node as well. It’s more hassle than it’s worth to have to specify different images for the different architectures. I already build my own copies of images, so I decided to start building all my images as multiarchitecture images. ...

Motivation I wanted to ensure any data I put into my ARM k3s cluster is backed up to prevent data loss. I no longer recommend duplicacy. Instead, read my article on restic backups on TrueNas instead. ...

I had a bunch of cruft in start scripts that would determine the IP of my laptop and set it as an environment variable to pass to docker-compose and it turns out that with Docker for Mac you don’t have to do all that work - just use docker.for.mac.localhost as a hostname.
