Swap on K8s nodes? Containers hang instead of OOM-killing—etcd suffers, control plane cascades. 2 fixes: resource limits + etcd HAProxy LB. Protect your cluster! 👇

Finally completed the upgrade of all of the five @midgaard #Kubernetes nodes to what I colloquially refer to as midgaard-v3.

Same standard #Hetzner nodes with a couple of #NVMe sticks and around 10TB of spinning metal for bulk storage. Much simplified partition layout. NVMes used for caching […]

etcd: The Cluster Maestro etcd: the 20 MB key-value store that keeps Kubernetes—and every cloud-native cluster—consistent, highly available and fast.

etcd is the cluster’s heartbeat: 20 MB that keep K8s, locks & services in sync. What’s your 3 A.M. etcd war story?

Diving into Kubernetes' Watch Cache Understanding how Kubernetes apiserver caches etcd, the 3-second timeout, and K8s 1.34 consistent read feature

🤔 Have you ever wondered how #kubernetes caches #etcd?

✍️ I just published a new deep-dive into K8s watch cache: per-resource Cachers, waitUntilFreshAndBlock(), and progress notifications for quiet resources.

Raft is production-ready. Etcd (Kubernetes' storage) and HashiCorp use it. Nomad, Vault, CockroachDB and other modern SQL DBs rely on Raft for consistency across instances. Consistency comes at a cost. #Databases #Raft #DistributedSystems #Etcd #Kubernetes

A screenshot from Github. A change bumps the etcd v3 client from 3.5.22 to 3.5.24, and that involves bumping Go to 1.24.

One of the main things that annoy me in the #Golang package ecosystem. A patch update of a dependency brings in a requirement of a new compiler version. What are the chances that #etcd folks sincerely believe they're following semver?

The reason given is […]

A core challenge for massive K8s clusters is etcd, its distributed key-value store. It becomes a significant bottleneck, impacting both scalability and performance as node counts soar, pushing the system's limits. #etcd 2/7

I've been doing things I shouldn't with #Kubernetes. We're using a replicated #MinIO cluster as the storage backend on #mstdndk, which requires a boat load of storage, especially if you forget to specify any kind of retention. So far, the quick workaround for a full disk, was just to expand the […]

Hitting etcd limits as your Kubernetes clusters scale?

This blog breaks down why sharding isn’t the answer, and how virtual clusters offer isolated control planes without the complexity.
