Upgrading Hundreds of Kubernetes Clusters
We also leverage tools like Kubent, popeye, kdave, and Pluto to help us manage API deprecations (when Kubernetes deprecates features in updates) and ensure the overall health of our infrastructure.
- Best Practices for Upgrading Kubernetes?
-
Updating from 1.25.15 to 1.26.10
kubent has been my goto for this - you point it at your cluster, tell it the target version you want to use, and it'll let you know if you have any depreciated resources and what you'll need to change. It's simple to use, quick, and just does the job.

How do you handle continuous k8s cluster version upgrades in your organization?
You have to constantly run tools like https://github.com/doitintl/kube-no-trouble / https://github.com/FairwindsOps/pluto.

Upgrading our EKS from 1.21 to 1.22
A great tool for checking depreciations is kubent/kube-no-trouble: https://github.com/doitintl/kube-no-trouble

strategy to upgrade eks cluster
https://github.com/doitintl/kube-no-trouble can be used to check for deprecated/removed APIs - you'll need to fix these in your codebase. You should fix these before upgrading your cluster
- choose from Two strategies we can implement to upgrade eks cluster
- Amazon EKS now support Kubernetes version 1.25

eks cluster upgrade Anyone has done eks cluster upgrade to upgrade the cluster from 1.21 to 1.22 there are some api resources kind need to changed, which need changes in manifest file changes. how do we identify the helm charts that are using these resources ? https://docs.aws.amazon.com/eks/lat
Just upgraded a few clusters from 1.21 to 1.24 the past few weeks. Used kubent (Kube No Trouble https://github.com/doitintl/kube-no-trouble) before upgrading and reviewed the output. Pretty painless process all in all.

Upgrading Hundreds of Kubernetes Clusters
When it came to deployment, I had several options, and I chose the hard way: deploying Kubernetes on bare metal nodes using KubeSpray. Troubleshooting bare metal Kubernetes deployments honed my skills in pinpointing issues. This hands-on experience provided a deep understanding of how each component, like the Control Plane, kubelet, Container Runtime, and scheduler, interacts to orchestrate containers.

Zarf: K8s in Airgapped Environments
Worth noting that if you like ansible, Kubespray has had documented air-gap installation since 2018 https://github.com/kubernetes-sigs/kubespray/commit/963c3479...

How many of you are running kubernetes on prem?
About 1yr ago I ran k8s with 300 nodes using kube spray https://github.com/kubernetes-sigs/kubespray . Never had any real issue with it. We did finally move to the cloud though.

Learning to setup my own k8s cluster
I would highly recommend https://github.com/kubernetes-sigs/kubespray
- Need some help configuring a private Docker registry in Kubernetes
-
Building your own Kubernetes distribution
We build our own distro called Compliant Kubernetes, and we use (a fork of) kubespray to install the base Kubernetes layer. Our distro is entirely open source, so you can use it as a reference, if you want.
-
Is being proficient in Kubernetes enough?
If you want to run Kubernetes on VM's you can look into kubespray and play around with the options for installing and checking the configuration after the fact.
What are some alternatives?
kubepug - Kubernetes PreUpGrade (Checker)
kubeadm - Aggregator for issues filed against kubeadm
