Installing and Configuring kubectl

kubectl is a CLI utility for running commands against Kubernetes clusters. It's required for many maintenance and administrative tasks in Rancher 2.x.

Installation​

See kubectl Installation for installation on your operating system.

Configuration​

When you create a Kubernetes cluster with RKE2/K3s, the Kubeconfig file is stored at /etc/rancher/rke2/rke2.yaml or /etc/rancher/k3s/k3s.yaml depending on your chosen distribution. These files are used to configure access to the Kubernetes cluster.

Test your connectivity with kubectl and see if you can get the list of nodes back.

kubectl get nodes
