Another distro goes to @cilium.io 🐝

First it was GKE. Then EKS. Then AKS. Now Canonical Kubernetes ☸️ At this point, it’s getting hard to find a major Kubernetes distro that doesn’t ship with Cilium.

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...

Kubernetes "native" sidecars are slated for GA in 1.33, so it's a good time to brush up on how (and why) to use them.

Solve this practical challenge by reworking a flawed pod, making it use a native sidecar:

CKA Practice: Upgrade Multi-Node Kubernetes Cluster | Challenge This exercise tests your ability to safely upgrade a multi-node Kubernetes cluster from version 1.30 to 1.31 following the standard upgrade procedure.

Unpopular opinion: The main value of CKA, CKAD, and CKS is not in the certificate itself but in the preparation phase.

Having said that, allow me to present a new iximiuz Labs challenge by Adam Leskis πŸ‘

It looks like it only supports GKE for the moment, other distributions will come soon, if I read the readme correctly

I think you need to use some specific key words like kubernetes or hashtags in your posts so they can be visible these feeds

I am not sure if this problem only for me, but your posts don't show on DevOps nor Kubernetes custom feeds πŸ˜” that explains why I see them kinda "late"

Great collection, Ivan!
Just a quick note to clear up a common misconception, It's obvious that Docker is the most popular tool for building OCI-compliant images from a Containerfile, but it's not the only one. Tools like Buildah/Podman also do a fantastic job and could enrich this list. 😊

First one uses #Cedar to @kubernetes.io authz and admission validation called "cedar-access-control-for-k8s"
