gossip-glomers VS cluster-api-provider-hetzner

There's a nice-looking series of exercises from fly.io: https://fly.io/dist-sys/

(I haven't actually done them myself yet, but they look great. Not a standalone resource, but good for practice)

Really worth noting that Maelstrom was the project they used to build the "Fly.io Distributed Systems Challenge" https://fly.io/dist-sys/ which was pretty popular at one point and discussed here, too. https://news.ycombinator.com/item?id=34897723

LiteFS works similarly to async replication you'd find in Postgres or MySQL so it doesn't try to be as strict as something running a distributed consensus protocol like Raft. The guarantees for async replication are fairly loose so I'm not sure Jepsen testing would be useful for that per se.

On the LiteFS Cloud side, it currently does streaming backups so it has similar guarantees but we are expanding its feature set and I could see running Jepsen testing on that in the future. We worked with Kyle Kingsbury in the past on some distributed systems challenges[1] and he was awesome to work with. Would definitely love to engage with him again.

They have really good tech blog posts. Also, they have https://fly.io/dist-sys/

Gossip Glomers https://fly.io/dist-sys/ by fly.io is a great way to learn distributed systems. They are fun to solve challenges. zio-maelstrom helps you get started faster in Scala!

There’s also this to practice https://fly.io/dist-sys/

Yeah no the embedded stuff is more a hobby, I'm interested professionally in stuff like what you said you're doing now in another comment, distributed systems and such. Infrastructure for cloud providers, that kind of thing. Right now I'm doing this distributed systems challenge series thing https://fly.io/dist-sys/ which should be cool to put on my github.

Hetzner Cloud is officially supported, but that means setting up VPSs in Hetzner's Cloud offering, whereas this project was intended as a more or less independent pure bare-metal cluster. I see they offer Bare Metal support as well, but I haven't dived too deep into it.

I haven't used KubeOne, but I have previously used Syself's https://github.com/syself/cluster-api-provider-hetzner which I believe works in a similar fashion. I think the approach is very interesting and plays right into the Kubernetes Operator playbook and its self-healing ambitions.

That being said, the complexity of the approach, probably in trying to span and resolve inconsistencies across such a wide landscape of providers, caused me quite a bit of grief. I eventually abandoned this approach after having some operator somewhere consistently attempt and fail to spin up a secondary control plane VPS against my wishes. After poring over loads of documentation and half a dozen CRDs in an attempt to resolve it, I threw in my hat.

Of course, Kubermatic is not Syself, and this was about a year ago, so it is entirely possible that both projects are absolutely superb solutions to the problem at this point.

For anyone interested in Kubernetes on Hetzner, there's a really interesting CAPI provider being actively developed:

https://github.com/syself/cluster-api-provider-hetzner

Just a hint running ML Workloads on Hetzner is pretty cheap! You could use for managing k8s: https://github.com/syself/cluster-api-provider-hetzner

we (Syself) release Cluster-API Provider Hetzner v1.0.0-beta.16.

ah okay they come from the upstream cluster-api project. The caph project implements only the infrastructure provider part of Cluster API.

you can easily use it with https://github.com/syself/cluster-api-provider-hetzner

I would use cluster-api-provider-hetzner from Syself.
