I don't get Kubernetes
No real content, just me ranting.
There are some ;) who take great joy in Kubernetes. I never really understood how I could use it.
Okay, so, very simplified, K8s let’s you say “I wanna run these services (Docker containers) on my cluster (various computers/servers), optionally with redundancy”? Well, I only have one “server” in my “homelab”, and then 3 VPS or so. Only one of them runs something in Docker/Podman.
I can’t imagine/don’t understand how I would run, say, Nextcloud in K8s. I want to know which server is currently running it, and where the data is stored. Especially with something like Nextcloud, I want to have the Nextcloud application, the database, and the data store on one VPS, without any indirections, without any communication over the internet or a VPN, via some proxy software. From what little I’ve heard about K8s (forgive me my ignorance), I had more questions that I could answer. K8s seems really complex, because it
hascan have so many moving parts (yes, you can probably run a very basic setup, most of the components seem optional). I don’t want my database suddenly moved around to somewhere else.That is to say: I never had a use case of trying out K8s. No actual, real one. I could probably construct one if I tried really hard. But, eh. “My current setup works”.
My attempt to run K8s on my Proxmox via LXC all failed, even if they’re privileged containers, probably because I need to mount Linux Namespaces, or load specific kernel modules on Proxmox itself so they can be loaded in the LXC containers as well (???).
