terraform-hcloud-kube-hetzner
Optimized and Maintenance-free Kubernetes on Hetzner Cloud in one command!
Project mention: Kubernetes on Hetzner: cutting my infra bill by 75% | news.ycombinator.com | 2024-12-01This 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.

Terraform Best Practices free ebook translated into 🇬🇧🇦🇪🇧🇦🇧🇷🇫🇷🇬🇪🇩🇪🇬🇷🇮🇱🇮🇳🇮🇩🇮🇹🇯🇵🇰🇷🇵🇱🇷🇴🇨🇳🇪🇸🇹🇷🇺🇦🇵🇰 (by antonbabenko)
Project mention: Using Terraform Workspace for AWS multi account archtetctures | news.ycombinator.com | 2025-02-04I generally consider the AWS CLI configuration to be something that's unique to a developer's workstation, and shouldn't be referenced in terraform code (in the form of tying the workspace name to your AWS profile name).
This would only work if all developers on a team have synchronised the same AWS CLI config (which to me is like asking people to synchronise dotfiles, not something I'd be willing to do).
My go-to architecture for multi-environment tends to be this, as it lends itself relatively well to Git Flow (or GitHub Flow): https://github.com/antonbabenko/terraform-best-practices/tre...
