I think you should add some screenshots to your homepage. people might not be interested in trying it out before seeing what they're gonna get. also –do you think you can make this work with CC using HTTPS_PROXY as well?

@ericchiang.bsky.social hey question about your synctest blog: do you really need that "+ time.Millisecond" or is there any determinism that the goroutine will get to run 3 times without it? oblique.security/blog/go-sync...

or maybe they're calling the bluff? so he has to either give the deets or perjure himself.

Most people think the Kubernetes scheduler makes scheduling decisions itself. Well, it doesn’t. The real power lies elsewhere. 🧵 Let’s talk about how the kube-scheduler is actually a plugin-first orchestration engine, not a decision-maker.

I only post my technical content on LI and I actually get the same number of engagements/views as X (where I have 10x more followers), it's a pretty good channel to get the word out about technical blogs etc.

Anyone have recommended readings on any scalable k8s multi-cluster work API implementations? Planning to roll out a similar model on our own and I want to study the state of the art and the rationale behind the existing model.

#KubeCon schedule is out! Team LinkedIn will give 3 talks this year (myself included): 1️⃣ Making Application Rollouts Observable (lnkd.in/gmnM-8Z4) 2️⃣ How We Upgrade the Whole ML Training Fleet Bi-weekly(lnkd.in/gG_a_Etc) 3️⃣ Evicted! All the Ways Kubernetes Kills Your Pods (lnkd.in/ggm9HKZF)

ahmet alp balkan @ahmet.dev · 30/07/2025

yeah we do that but it would be so much better if we didn't need to. all our microservices and our entire service infra except for CNCF components use push model, and we have to run a otel collector just for those.

ahmet alp balkan @ahmet.dev · 30/07/2025

Our team at LinkedIn will give 3 talks at the #KubeCon 2025! Looks like we'll be meeting in Atlanta again. 👋🏼 Stay tuned.

ahmet alp balkan @ahmet.dev · 30/07/2025

I think this largely assumes OLTP pushing to Prometheus backend, whereas it would be good to have no Prometheus at all in the picture. Admittedly, nearly the whole CNCF ecosystem makes a big assumption around Prometheus, whereas projects like Kyverno catching up to using OTel SDK.

120

ahmet alp balkan @ahmet.dev · 30/07/2025

Yeah but how do we change all these off the shelf components to use OTel SDK instead of Prometheus?

110

ahmet alp balkan @ahmet.dev · 29/07/2025

Does anyone know why all cloud-native open source ecosystem uses pull model to expose their /metrics (instead of pushing the metrics)? Pull model is really poor when the metric cardinality exposed on a single endpoint increases.

pedantic point: creation idea of Israel and mass Jewish migration to the British Mandate Palestine predate WW2 by many decades (Theodor Herzl, First Zionist Congress, the Uganda plan, Balfour declaration, ...)

We’ve been systematically evaluating the scalability of our fleet’s control planes, and the recent work on storage layer scalability in the Kubernetes community is going to prove pivotal as we scale further! Check out what we’ve been upto for the past couple of weeks ♥️

As we test Kubernetes clusters beyond the supported 5,000+ nodes limit at LinkedIn, we're finding out 'List API' calls are a bottleneck in cluster reliability. So I'm publishing a deep dive about why this is a problem and what you can do about them. ahmet.im/blog/kuberne...

no man stop right there. it's a timesink.

ahmet alp balkan @ahmet.dev · 03/07/2025

Yeah, we also plumb all the data to mysql over time and build UIs on top. This is more for ad hoc surgical queries for nodes matching a particular label (plus I wanna be able to use this in my next jobs too 😛)

ahmet alp balkan @ahmet.dev · 03/07/2025

have you considered Hugo instead? it's not extremely feature rich or JS-heavy like Docusaurus, and is a bit more barebones, yet works well in sites like k8s.io.

ahmet alp balkan @ahmet.dev · 23/06/2025

Open sourcing a new kubectl plugin called `kubectl node-resource` that queries allocations/utilizations for all/subset of the Kubernetes nodes. It has optimizations for large clusters. We've needed this in our set up to quickly answer questions. github.com/ahmetb/kubec...

DAYS SINCE ETCD BACKUPS SAVED OUR ASS IN PRODUCTION: 0 If you manage your Kubernetes clusters and think you won’t lose your etcd, you’re almost certainly wrong. It takes years for the disaster to happen and you’ll be glad you have invested in building a backup/restore system.
