I've used docker-compose, k8s, and NixOS myself, being from a similar technical background as the author, but I find myself disagreeing with some of the author's opinions on the technologies. They're not wrong of course, but I've had different experiences. k8s: Installing and using k8s can indeed be a nightmare. In my job, we use Azure, so it's not so bad since launching a cluster is mostly handled by Azure. Setting it up for personal use is less fun. The mountains of YAML you can end up using to deploy even semi-complex services is even less fun. That being said, I've been wanting to use it for a personal project (distributed cluster using cloud VPSs and bare metal at home connected using WireGuard). I just wish it was smaller and faster. Most guides recommend 2Gb of RAM and 2 CPU for the smallest of small deployments. docker-compose: I actually love docker-compose for my personal stuff. I have an intel NUC hosting homeassistant, pihole, caddy, deluge, jellyfin and a handful of other stuff. Everything lives in a series of folders for each service. Backups (both data and code via git), disaster recovery, and just general reasoning about of it is so easy. The docker-compose files are small and easy to read. I also find docker-compose to be about as immutable as you'd like it - version control your docker-compose directories, pin your image SHAs, and you're in a good place. Or don't, and it will still work pretty well. NixOS: I've done it. I installed it on my Framework Laptop since it was all the rage at the t ime. I lived with it for about a year, and it was okay - for day-to-day use - AFTER I had spent weeks learning how to use NixOS. I will freely admit it's an awesome technology in some respects. But the documentation just was not there. It was way too hard to learn how to do even basic tasks. I thought nix flakes might be the "aha" moment I was looking for, but I gave up trying to get that to work after a couple of days of troubleshooting. Don't even get me started on trying to package up something from scratch. As a random example, I googled "packaging python for nix" and the top result [1] is just way too complex for something that should be pretty simple. The example includes some abomination of a .nix file with inline bash and python scripts. I don't really know where I'm going with this. I really do like the idea of NixOS. I just wish it was much, much easier to reason about. Curious to hear what others make of this. [1](https://nixos.wiki/wiki/Packaging/Python https://nixos.wiki/wiki/Packaging/Python)
