Internal Acces
- UDP 4789, node to node, node to master and master to node: must be accessible for any host in the cluster, it is required for SDN communication between pods on separated hosts.
- TCP 53 or 8053, node to master, master to master: used by internal DNS traffic.
- TCP 8443 node to master: access to API.
- TCP 10250 master to node: a node endpoint to be used by the master for communication.
- TCP 4001 master to master: 4001 used for non-clustered etcd to accept change in state.
| 2380 | TCP | etcd | clustered etcd uses 2380 to listen for peers, for leader election and peering connection when using standalone etcd |
| 2379 | TCP | etcd | etcd uses the port for client requests, used for state change traffic |
External Access
- TCP 8443 - API access, web console, CLI.
- TCP 80, 443 - ports opened and bound to the default router.
