Ports Used by NodePort Services

It specifies the range of ports that can be used by NodePort Services. The default range is 30000 to 32767.

Value Range

From 20106 to 32767

From 30000 to 32767

Modifiable

Yes

Scope

CCE standard and CCE Turbo clusters

Suggestions

Set the parameter to a range from 30000 to 32767.

If the port is less than 20106, there may be a conflict with the CCE health check port, which can cause the cluster to become unavailable.

If the port is greater than 32767, there may be a conflict with the ports in net.ipv4.ip_local_port_range, which can affect the network performance.
