Prometheus

In Swarm-only mode, MKE runs the Prometheus server and the authenticating proxy in a single container on each manager node. Thus, unlike in conventional MKE installations, you cannot configure Prometheus server placement. Prometheus does not collect Kubernetes metrics in Swarm-only mode, and it requires an additional reserved port on manager nodes: 12387.
