Port Requirements

Port Requirements

KubeSphere requires certain ports for the communications among services. If your network is configured with firewall rules, you need to ensure infrastructure components can communicate with each other through specific ports that act as communication endpoints for certain processes or services.

Service	Protocol	Action	Start Port	End Port	Notes
ssh	TCP	allow	22
etcd	TCP	allow	2379	2380
apiserver	TCP	allow	6443
calico	TCP	allow	9099	9100
bgp	TCP	allow	179
nodeport	TCP	allow	30000	32767
master	TCP	allow	10250	10258
dns	TCP	allow	53
dns	UDP	allow	53
local-registry	TCP	allow	5000		For the offline environment
local-apt	TCP	allow	5080		For the offline environment
rpcbind	TCP	allow	111		Required if NFS is used
ipip	IPENCAP / IPIP	allow			Calico needs to allow the ipip protocol

When you use the Calico network plugin and run your cluster in a classic network on cloud, you need to enable both IPENCAP and IPIP protocol for the source IP.
