Docker Networking Stack

Currently I am trying to make my docker container's network stack be the same as my machine's in my docker-compose yml. I saw on the docker docs you can use "hostnet" to use your own network stack. I am using this but I keep getting an error saying... services: xxxxx: xxxxx: networks: hostnet:{}

networks: hostnet: external: true name: host

networks.hostnet value Additional properties are not allowed ('name' was unexpected)

What is wrong, and is there also a way to configure a docker compose file so that my container will have the same Network ID?

This can be achieved using:

network_mode: "host"

in the definition for your service. See Docker's compose file documenting for more details on this: https://docs.docker.com/compose/compose-file/#network_mode

Note that I personally consider this the option of last resort. If you can achieve your goals by publishing a single port instead of disabling the network namespacing features of docker, your solution will be more secure and portable.
