Huawei Cloud DevBridge Development Tunnel Create and manage DevBridge development tunnels to securely expose local development services to remote devices via Huawei Cloud relay infrastructure. Overview DevBridge is a development tunnel service that allows developers to expose local services (web servers, APIs, debug endpoints) to remote devices without opening public inbound ports. The CLI tool ( ) manages tunnels, ports, host connections, and connect sessions. Host and Connect both initiate outbound connections to the relay service, so the hosting device does not need a public inbound port.…
