Restrict configuration file permissions.
$ sudo chown root:root /etc/k0s/k0s.yaml
$ sudo chmod 600 /etc/k0s/k0s.yaml
Validate initial configuration.
$ sudo k0s config validate --config /etc/k0s/k0s.yaml
Install single node k0s controller.
$ sudo k0s install controller --single --config /etc/k0s/k0s.yaml
Alternatively, use --enable-worker --no-taints instead of --single if you plan to extend cluster with additional worker nodes later.
Inspect initial service status.
$ sudo k0s status
Error: status: can't get "status" via "/run/k0s/status.sock": Get "http://localhost/status": dial unix /run/k0s/status.sock: connect: no such file or directory
Start k0s controller.
$ sudo k0s start
You can also inspect the systemd service status.
