terraform-hcloud-kube-hetzner

Anyone here using https://github.com/vitobotta/hetzner-k3s Or https://github.com/kube-hetzner/terraform-hcloud-kube-hetzne... For a K3S cluster? Would love to hear any experience. Thanks!

sounds and looks great! There are many good projects out there to deploy Kubernetes https://github.com/kube-hetzner/terraform-hcloud-kube-hetzne..., https://github.com/vitobotta/hetzner-k3s. However, I like that yours is manageable via Dashboard and you install basic applications. Feels way smoother than Terraform templates or CLI tools. Setting up kubernetes yourself with k3s and deploying a HA database with cnpg is so simple nowadays. It works great until some day you face an issue that you can't fix without diving deep into the details e.g. debugging your CNI or the implementations of specific operators to understand reconciliation errors. I faced countless of these issues such as: - your Postgres CNPG failed during failover and can't recover on it's own - Postgres WAL archiving suddenly doesn't work anymore after an update. - Cluster

For anyone interested I am in the last stages of building a course operating around Kube-Hetzner (https://github.com/kube-hetzner/terraform-hcloud-kube-hetzne... 3k github stars). Basically a lot of scripts that shows how this works and how to perform backups, restores etc... and a lot of exercises for common use cases and failure troubleshooting. Intentionally NOT abstracting away anything so you can see how this works. Without understanding you are going to get stuck. Join the waiting list here: https://shipacademy.dev

There is this project to deploy k3s to Hetzner via Terraform: https://github.com/kube-hetzner/terraform-hcloud-kube-hetzne... It's not the smoothest thing I've ever used, but it's all self hosted and everything can be fixed with some Terraform or SSH. Great to see some managed Kubernetes on Hetzner!

Yeah so at the moment it kind of supports two options: 1. A single Hetzner VPS 2. An existing Kubernetes cluster. I usually use #1 for staging / development apps, and then #2 for production apps. For #2, I manage the number of nodes on the Digital Ocean side, and kubernetes just magically reschedules my workload accordingly (also can turn on auto scaling). I think the thing that you're getting at that is not supported is having Canine create a multi-node cluster directly within Hetzner. There is a terraform to create a Kubernetes cluster from hetzner, but this isn't currently installed on Canine. I'm not closed to trying it out, there were a few UI improvements I wanted to take a shot at first, but at the moment Canine assume's you have a cluster ready to go, or can help you walk through a K3s installation to a single VPS. https://github.

This is definitely some ChatGPT output being posted here and your post history also has a lot of this "While X, Y also does Z. Y already overlaps with X" output. I'd like to see your breakdowns as well, given that the cost difference between a 2 vCPU, 4GB configuration (as an example) and a similar configuration on AWS is priced much higher. There's also https://github.com/kube-hetzner/terraform-hcloud-kube-hetzne... to reduce the operational burden that you speak of.

I haven't used it personally, but https://github.com/kube-hetzner/terraform-hcloud-kube-hetzne... looks amazing as a way to setup and manage kubernetes on Hetzner. At the moment I'm on Oracle free tier, but I keep thinking about switching to it to get off... Well Oracle.

There is a nice one-click kubernetes for hetzner if you use the terraform module: https://github.com/kube-hetzner/terraform-hcloud-kube-hetzne... There is also a gpt that you can use that will genereate you the module block based on your requirements.

Hetzner and Kubernetes are not mutually exclusive. - https://github.com/kube-hetzner/terraform-hcloud-kube-hetzne... - https://www.hetzner.com/hetzner-summit --> "Managed Kubernetes Insights and lessons learned from developing our own Kubernetes platform"

I like Epinio which does the same but on top of kubernetes. It is backed by Suse and lightweight compared to KNative (which is the basis of GCP CloudRun for example), but being kubernetes based still requires more Resources than dokku or Piku. I still prefer k8s due to the vast ecosystem of mature solutions. And I can still run everything on a single box, it just needs to be a bit bigger. The new Hetzner CX42 with 8 vCPUs, 16 GB of RAM, and 160 GB of disk space for € 16.40 a month (€ 0.0273 per hour) is sufficient, and with the Kube Hetzner Project I can set up a kubernetes cluster with auto updating microos in 5 minutes. https://github.com/epinio/epinio/ https://github.com/kube-hetzner/terraform-hcloud-kube-hetzne...

I run my own cluster too, it is managed by one terraform file which is maintained on GitHub [0]. Along with that I deploy everything on here with 1 shell script and a bunch of yaml manifests for my services. It's perfect for projects that are managed by one person (me). Everything is in git and reproducable. The only thing I am doing unconventional is that I didn't want to use github actions, so I use Kaniko to build my Docker containers inside my cluster. 0 https://github.com/kube-hetzner/terraform-hcloud-kube-hetzne...

Hetzner starting with https://github.com/kube-hetzner/terraform-hcloud-kube-hetzne..., plus registry using DigitalOcean.

It's not even close to major public cloud providers, but this is my setup: * https://github.com/kube-hetzner/terraform-hcloud-kube-hetzne... (Terraform, Kubernetes bootstrap) * Flux for CI * nginx-ingress + Hetzner Loadbalancer (thanks to https://github.com/hetznercloud/hcloud-cloud-controller-mana...) * Hetzner storage volumes (thanks to https://github.com/hetznercloud/csi-driver) Kube-Hetzner supports Hetzner Cloud loadbalancers and volumes out of the box, though it also supports other components.
