11.14. Binding Applications to Ports

All ports less than 1024 are reserved for OpenShift Enterprise operations, and developers cannot bind to these ports. However, ports greater than 1024 are available for binding, and the following table shows the commonly used ports.

Important

While the following ports are suggestions for available applications or gears, ports 2303 - 2308 are reserved for OpenShift SNI Implementation, and port 10050 is reserved for the OpenShift Enterprise Zabbix agent. You cannot bind to these ports.

11.14.1. Configuring WebSocket Ports
링크 복사

Because the main routing layer is currently based on Apache, WebSocket can be used by connecting to specific ports on an application. WebSocket connections are supported with browser based applications on OpenShift Enterprise, allowing bidirectional communication without requiring multiple, open HTTP connections. The TCP based protocol uses HTTP as an initiation handshake which is handled as an upgrade request. If successful, the connection remains open and switches to the WebSocket protocol.
For plain WebSocket connections (ws://), requests are directed to port 8000, while WebSocket Secure connections (wss://) use port 8443, as shown in the following example:
  • http://example.example.com:8000
  • https://example.example.com:8443
