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...

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...

Glad to have @madhavjivrajani.bsky.social join us at LinkedIn compute team this summer. I’m constantly impressed by the depth of his kube-apiserver expertise.

🇬🇧 Looking forward to seeing y'all at our #KubeCon talk about how we're building a bare-metal compute platform at LinkedIn to run thousands of services on high-6-digit number of machines!

New article on my blog that explains all the various ways Kubernetes can evict your workloads. This wasn't all documented in one place so I'm hoping this helps the teams operating with Kubernetes in production. You'll also find a cheatsheet in the article. ahmet.im/blog/kuberne...

At LinkedIn, we run stateful systems on bare metal servers as a first class citizen on Kubernetes. That's why we built our own stateful workload operator.
Join our #KubeCon talk to learn why StatefulSet didn't cut it for us and how we work with local storage. kccncna2024.sched.com/event/1i7n9/...
