Accessing localhost from docker container?

Question

Docker

I'm really bad at everything so just tell me what to write in docker-compose so that the container can access localhost:8080 on the machine itself

Thanks a lot!

Answer 1

You will have to remove isolation from the network , otherwise you will not be able to access localhost on the host machine from the container.
Or, you can make the service on the host machine listen on all interfaces and access it from the container at the gateway address in the virtual network to which the container is connected.

Answer 2

Add to docker-compose

extra_hosts:
      - "host.docker.internal:host-gateway"

In code, use to access localhost:8080host.docker.internal:8080
