I’ve had most of my stuff running a k3s “cluster” for the past half a year or so. The whole setup runs on a single $5-a-month Digital Ocean droplet with 1vCPU and 1GB of memory.
Needless to say, it doesn’t take much to bring the whole thing to its knees. While it has no issues dealing with the little traffic my blog receives, I would accidentally bring it down occasionally when I install a Helm chart that turned out to be much heavier than I’d thought.
Having played around with the managed Kubernetes offerings of various cloud players (DO, AWS, GCP), I was wondering if it was possible to do this cheap. My site doesn’t have much traffic or anything complicated really, so running it off a $5 DO droplet is reasonable. Sadly managed Kubernetes offerings won’t come out so cheap. (Sure I could leech off the starting $300 GCP credit for a year then keep hopping accounts, but…)
Then I read about k3s. The people behind Rancher made it as a lightweight (but functionally complete) Kubernetes distro. Lightweight, they say… Just how light? (Imagine a weird maniac light in my eyes here.) Could I run it on a $5 droplet?
I think many people of my profession got recommended a certain article by Medium in their weekly digest. The launch-introduction post by Garden got my attention too. I’ve been trying to figure out how to deal with developing on Kubernetes, so every drop of information in that regard is much welcome.
