Here is a sample Compose file from the voting app sample used in the ![]() Ports will be exposed to the host machine to a random port or a given port. ![]() So I tried to run with '-p 5050', for example. However, when I run below script, it will default bind in 80 port: sudo docker run -namemyname -network host -d webapi:1.0.0 -restartalways. Ports mentioned in docker-compose.yml will be shared among different services started by the docker-compose. Is it possible to config the port number in docker under 'host mode' I wanna bind the application to 5050 port instead of 80 port. The latest Compose file format is defined by theĬompose Specification open_in_new and is implemented by Docker Compose 1.27.0+. Either specify both ports (HOST:CONTAINER), or just the container port (a random host port will be chosen).

For full details on what each version includes and There are several versions of the Compose file format – 1, 2, 2.x, and 3.x.

A bridge can be a hardware device or a software device running within a host machines kernel. These topics describe version 3 of the Compose file format. In terms of networking, a bridge network is a Link Layer device which forwards traffic between network segments. Compose V2 has replaced it and is now integrated into all current Docker Desktop versions. Reference / Compose file reference / Legacy versions / Version 3 Compose file version 3 referenceĭocker's documentation refers to and describes Compose V2 functionality.Įffective July 2023, Compose V1 stopped receiving updates and is no longer in new Docker Desktop releases.
