How to start Docker container so that it uses Host Network?

Question

I am starting a dockerized SpringBoot based webapp which needs Postgre to start, I have Postgre in my host machine. So how can start my container so that it uses the Postgre from host machine?

Eleven · Accepted Answer

You are looking for host networking mode. That way your docker container will have all access to host networking hence the Postgre which is running in host. Add `--network host` while starting your container.

```sh
docker run  -d --network host -it  your_app:your_app_tag
```
