While working on Kubernetes cluster environment, there will be times when you run into a situation where you need to delete pods from one of your worker nodes. You may need to debug issues with the node itself, upgrade the node, or simply scale down your cluster. The action of deleting a...
Kubernetes is designed to be fault tolerant of worker node failures. There might be different reasons a worker node becomes unusable such as because of a hardware problem, a cloud provider problem, or if there are network issues between worker and master node, the Kubernetes master handles it e...
In this post, we will explain how to add new Kubernetes worker node step-by-step. We are assuming on-prem Kubernetes cluster is up and running on Ubuntu 24.04. Scaling your Kubernetes cluster is essential as your applications grow. Adding new worker nodes to your existing on-prem Kubernetes ...
Worker node components: Learn about Kube Proxy, Kubelet, Container Runtime Addon Components:CoreDNS, Network plugins (Calico, weave, etc), Metric Server Cluster high availability:Most organizations use managed Kubernetes services (GKE, EKS, AKS, etc). So the cloud provider takes care of the clust...

The Kubernetes scheduler schedules the workflow job pods on available compute. As of this writing, PrintOS uses Amazon EC2 On-Demand Instances for production. For non-production clusters, it creates Amazon EC2 Spot Instances as EKS worker nodes to drive the cost further...

Worker nodes have two major logs to look at: kubelet logs and kube proxy logs. After these, you should also include CNI pod logs, CSI logs, and kube proxy logs. In addition, the Kubernetes events per node are vital, as these show what’s happening at the node level. ...
Set the worker node to be unschedulable: kubectl cordon kind-worker. Then deploy the nginx manifest below, which specifies the kind-worker node in the spec. You'll see that, despite the node being unschedulable, the Pod was still deployed and running on it. apiVersion: apps/v1 kind: De...
