The default port is 8080. This conflicts with kube-router, which since 2.x fails if it cannot bind to its metrics port. This leads to a situation where the default configuration for a single node k0s cluster is broken, as kube-router will go into a crash loop. Kube-router 1.x will not be able to provide metrics, but will simply log the error and move on. The integration tests did not cover this case properly, as the kube-router manifests did not specify a readiness probe that the inttests need to detect problems with daemon sets. Port 2380 was chosen because it is normally used by etcd. Kine also uses port 2379 for the client API, so why not use 2380 as well?
