Hello, We have a old kubernetes cluster(v1.20.15) which is not upgraded for a long time. We got some time to work on it now. I need some suggestion on the best path to perform the upgrade. According to my knowledge we can upgrade to one major version one after the other so it would take 8 times to get the cluster upgraded till v1.28.12. Is there a possibility to upgrade to latest by skipping the major version one by one?

Hello Guys, This is an interview question. The interviewer asked what can we do to make sure at the node level that pods do not run as root user ? My answer was, if we run the kubernetes server and client components as a non-root user then the container it spaws will also run as a non-root user. Is that right ? Can we run the kubernetes server and client components as a non-root user and would it spawn a non-root container if we did ? 1 post - 1 participant Read full topic ..read more

folks, I need you’re help to understood what happens on the cluster at the moment. We have a service that works fine on all probes, but got a strange exit code status of 137 with reason as error only, so I’m not sure how to debug further. It’s not an OOM issue as the kernel does not show anything with sudo dmesg -wH on that node. I’ll provide my analysis bellow and appreciate any response on this topic Cluster information: Kubernetes version: v1.30.1-eks-49c6de4 Cloud being used: AWS Installation method: EKS Host OS: AMI 1.30.0-20240703 CNI and version: v1.18.2-eksbuild.1 CRI and version: co ..read more

I’m trying to submit high volumes of one-off commands using Kubernetes. For this, I initially tried using k8s Jobs which seems to be the advertised feature for this use-case. When I submit my tasks as 100 different k8s Jobs (with completions=1), it takes ~30s to finish. All jobs run the ‘true’ command (I can share the complete JobSpec, if needed). But when I run submit the same tasks (true commands) directly as k8s pods, it’s much faster. Submitting 100 pods and waiting for them to finish takes just ~10s. 3x faster than Jobs! My understanding is that Jobs also create Pods underneath (and do so ..read more
