Hetzner-k3s v0.5.4 is out with support for multi zonal Kubernetes clusters

The Founder's Submission

Direct narrative and submission text authored by @SkyLinx on Hacker News:

For any Hetzner Cloud customers who may be interested: I have released v0.5.4 of a tool I created [1] to manage Kubernetes clusters in Hetzner Cloud. This release adds support for multi zonal clusters for higher availability as well as the ability to specify extra args for each Kubernetes component, so that you can enable feature flags and things like that.

For those not familiar with this tool: it's a tool to quickly create production clusters in Hetzner Cloud using k3s, so creating a cluster takes only a couple of minutes or less.

For those not familiar with Hetzner: it's a German provider that offers an awesome service, servers with great performance and reliability for a fraction of the price the other providers charge. If you mostly need compute and not the many services the bigger providers offer, you can save quite a bit of money with this provider. They have 2 locations in Europe (in Germany and one in Finland) as well as one location in the US (Ashburn, Virginia).

Looking for feedback and suggestions of features I could add. Thanks!

Retrospective Overview & Key Insights

Distilled analysis of the business dynamics, operational challenges, and strategic takeaways:

In this technical retrospective (2022), @SkyLinx shares practical architectural lessons learned from running, scaling, or migrating production software under lean constraints.

Core Principles for Independent Builders:
1
Defaulting to simpler architectures (such as monolithic frameworks, SQLite, or managed VPS) prevents early engineering bankruptcy.
2
Evaluating true compute and egress costs reveals that high cloud bills can often be slashed by 80%+ through judicious re-platforming.
3
Code you write at 2 AM as a solo engineer must be easy to debug six months later without complex microservice dependencies.
Community Debate Themes:

HN engineers debated the tradeoffs between cloud convenience and raw server economics, database indexing strategies, and resisting premature architectural complexity.

1. Does it support autoscaling (up and down)? Do you have docs/links

2. What's the cost ($/instances/overhead) of going HA

3. How does this handle reliable/multiregion storage and data transfer (eg: if a region is having outage)?

4. Have you considered publishing this on the Hetzner community blog?

Can you submit the link to https://github.com/hetznercloud/awesome-hcloud/ , too?
