How do I execute the kubectl command on a slave node

[jepson66]

What should I do if I want to execute the kubectl command on the slave node？

Hi @jepson66

By default, MicroK8s worker nodes do not get an admin kubeconfig file. Instead what you can do is grab one from any of the control plane nodes and run kubectl manually, e.g.:

Print a kubeconfig file for the admin user by running this command on any of the control plane nodes:

microk8s config > kubeconfig

Then manually move this to ~/.kube/config on your worker node, and install kubectl, e.g. with sudo snap install kubectl --classic

cp /path/to/kubeconfig ~/.kube/config

# install kubectl, e.g. with snap
sudo snap install kubectl --classic
kubectl get pod

Hope this helps!

OK, thank @neoaggelos, I'll try it.

@neoaggelos，According to what you said, it is configured, but the slave node still cannot use the kubectl command

@jepson66 is it possible you have an alias of microk8s.kuebctl to kubectl? Could you try calling directly /snap/bin/kubectl and use the --kubeconfig <path_to_kubeconfig> just to be sure we are not picking up any config we are not supposed to?
