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. ...
One of the reasons I set up my cluster was that I’m running out of space on my NAS. I don’t want to buy a whole new chassis, and while I could have put individual file shares on each cluster node, that would be both inconvenient and not provide any data redundancy without a lot of brittle home-rolled hacks to rsync data from node to node. And since distributed file systems are a thing, I’d rather not resort to hacks. ...
I realized I forgot to include a parts list for the cluster in my ARM cluster post (all prices are as of March 3rd, 2019), so here we go. ...
I recently decided to set up a Kubernetes cluster in my basement, partly because I’d never set a cluster up from scratch by myself, and partly because my existing NAS was beginning to run out of headroom. ...
