Two ways to reach host

1. Use --network="host" in your docker run command, then 127.0.0.1 in your docker container will point to your docker host.

2. Get host IP by running following command. Then you should reach the host from container.

ip addr show docker0 | grep -Po 'inet \K[\d.]+'

# 172.17.0.1

Alias for docker-compose

Add the following parameter to your service:

    extra_hosts:
      - "host.docker.internal:172.17.0.1"

Then you can reach via the alias path.
