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.

so... a lot of this can be done with Fairwind's OSS tool Polaris... https://github.com/FairwindsOps/polaris
feels good that we've been addressing this for a bit already tbh.

An automatic diagnostic tool for Kubernetes cluster
KubeEye is an open-source diagnostic tool for identifying various Kubernetes cluster issues automatically, such as misconfigurations, unhealthy components and node failures. It empowers cluster operators to manage and troubleshoot clusters in a timely and graceful manner. Developed in Go on the basis of Polaris and Node Problem Detector, KubeEye is equipped with a series of built-in rules for exception detection. Besides pre-defined rules, KubeEye also supports customized rules.
