Configuration Inbound Rule
The Security Group at Deka Harbor has determined the port you can use. If you enter a port that is not specified, the message “The specified port is not allowed. Please check the port in the frontend configuration of the Load Balancer.” For a more detailed explanation of the ports that can be used, see Table below.
| Port | Description |
|---|---|
443 | This port can be used for secure communication via the HTTPS (Hypertext Transfer Protocol Secure) protocol. |
6443 | The port used by kubernetes to provide a secure server API management and authentication interface. |
80 | The port is used for unencrypted communication via the HTTP protocol but information sent via this port is not encrypted so it is not safe for use in environments that require data security. |
3100 | This port can be used for various services depending on the configuration. |
