k3s Default Installation Missing Config¶
If the k3s is installed using the default curl command, then it's running as a server without much access. The default access is 600 to /etc/rancher/k3s/k3s.config. You need access to this to run kubectl commands.
The best way to deal with this is to create a config (for now in the etc dir). First switch to sudo.
sudo su -
vim /etc/rancher/k3s/config.yaml
# Add the following to the yaml file
write-kubeconfig-mode: "0644"
Then stop and restart the service to enforce this new config.
sudo systemctl stop k3s
sudo systemctl start k3s
