Currently, I am running this by just specifying the port mappings from host to docker container, where I use the same port on both

eg :

version: '3.8'
services:
  api-server:
    build: '.'
    ports:
      - "8080:8080"

This is the correct approach. You shouldn't need host networking in most cases, and it doesn't work on non-Linux host OSes. – David Maze Apr 22 '22 at 10:02

You need to specify the network mode inside your service at docker-compose.yml. Add it like this:

version: '3.8'
services:
  network_mode: "host"
  api-server:
    build: '.'
