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 +~~has~~ can 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 (???). + |
