equivalent of --net=host in docker compose file when creating docker container

Question

I trieddocker run --net=host -d --name pdns-recursor pschiffe/pdns-recursor and it works. Now my goal is to use dockerfile to pass some environment without errors.

I tried:

networks:
  name: host

and

networks:
  name: "host"

and also the examples indicated here.

I always get an The Compose file './docker-compose.yml' is invalid because: services.recursor.networks.name contains an invalid type, it should be an object, or a null.

Any suggestions are much appreciated.

Solution

Use network_mode instead:

network_mode

Network mode. Use the same values as the docker client --network parameter, plus the special form service:[service name].

network_mode: "bridge"
network_mode: "host"
network_mode: "none"

You can use networks to specify host networking in swarm mode, by setting the driver of a given network to host.

Note that you say "dockerfile" but this isn't a Dockerfile but a Docker Compose file.

Yup, that was my bad I got confused. Will change it

[Noushad]

can we do this with a Dockerfile. ?

[user13539846]

Oh, thank you sir!

[Noushad]

can we achieve the same using a Dockerfile ?

[muru]

@Noushad no, there's nothing similar in the Dockerfile instructions. It might be possible by some custom Dockerfile syntax, but I don't know of any.

@muru Alright, thanks a lot for the clarification
