Too few sampled comments (1) to say how often HN recommends it.?
Why HN links it
Only one comment, which discusses k3s and the overhead of vanilla Kubernetes on small clusters rather than the post. The linked post covers building a bare-metal Kubernetes cluster on Raspberry Pi.
Summarised by Claude from a sample of 1 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
Writing on infrastructure, Go, self-hosting and homelabs.

HN discussionhttps://mrkaran.dev/ This is my personal blog where I pen down my thoughts on Containers, DNS, bits of Devops etc. I've been a self learner since the time I started programming and I feel penning down thoughts and reaching to a wider audience makes me learn those concepts even better. If you enjoy understanding concepts using an ELI5 approach, consider checking out my blog :)

HN discussionThanks! I pretty much did this as a learning/hobby side project. Back in 2021, I was dealing with a lot of K8s clusters and had recently learnt what about ndots[1]. That prompted me to build an easy to use DNS client which can avoid surprises about the host environment. I've built this using Go, my daily driver. It doesn't use any CLI frameworks, that was mostly out of choice as I didn't want to add external deps un…

HN discussionI'm working on Logchef: https://github.com/mr-karan/logchef It's an open-source (AGPLv3), purpose-built log analytics UI specifically for ClickHouse. I've been using ClickHouse for logs and love its power, but found the existing UIs either too heavy, too focused on ingestion (which we already have covered with tools like Vector/Promtail/Fluentbit/Logstash etc), or not ClickHouse-native enough. Logchef aims to be a l…

HN discussionugh it's great that k3s exists, but frustrating that kube can't hit this target on its own it seems like small clusters are not economical with vanilla kube. (I say this having frequently tried and failed to do this, but not having done napkin math on system pod budgets to prove it to myself generally). and this gets worse once you try to install any kind of plugins or monitoring tools. I really wonder if there's a…

HN discussionI've been using Clickhouse Keeper in production environment since it's first release and have been really happy. It makes setting up distributed tables in Clickhouse (replicas/shards) quite easy. The only issues I've seen is when inserting at a super high throughput (>1000/sec writes) which is actually more of a n issue with Clickhouse Merge Table tree settings rather than Keeper itself. I've also written about it h…

HN discussionI recently implemented the Bitcask paper in Golang and shared my learnings: https://mrkaran.dev/posts/barreldb/ https://github.com/mr-karan/barreldb/ Bitcask is an excellent paper that is not overwhelming to understand and offers a great stepping stone in building your own data stores. The simple yet powerful design of an append only file is eloquent and performant. I’d love to read about more such implementations,…
