- Note: `--api-port 6550` is not required for the example to work. It's used to have `k3s`'s API-Server listening on port 6550 with that port mapped to the host system.

- the port-mapping construct `8081:80@loadbalancer` means
- map port `8081` from the host to port `80` on the container which matches the nodefilter `loadbalancer`
- the `loadbalancer` nodefilter matches only the `masterlb` that's deployed in front of a cluster's master nodes
- all ports exposed on the `masterlb` will be proxied to the same ports on all master nodes in the cluster
