Cluster Access

The kubeconfig file stored at /etc/rancher/k3s/k3s.yaml is used to configure access to the Kubernetes cluster. If you have installed upstream Kubernetes command line tools such as kubectl or helm you will need to configure them with the correct kubeconfig path. This can be done by either exporting the KUBECONFIG environment variable or by invoking the --kubeconfig command line flag. Refer to the examples below for details.

Leverage the KUBECONFIG environment variable:

export KUBECONFIG=/etc/rancher/k3s/k3s.yaml
kubectl get pods --all-namespaces
helm ls --all-namespaces

Or specify the location of the kubeconfig file in the command:

kubectl --kubeconfig /etc/rancher/k3s/k3s.yaml get pods --all-namespaces
helm --kubeconfig /etc/rancher/k3s/k3s.yaml ls --all-namespaces

Accessing the Cluster from Outside with kubectl​

Copy /etc/rancher/k3s/k3s.yaml on your machine located outside the cluster as ~/.kube/config. Then replace the value of the server field with the IP or name of your K3s server. kubectl can now manage your K3s cluster.
