docker compose: inside container trying to ping host.docker.internal. but not working

Question

I have a docker-compose file and running containers

Inside one of the container i have to access the host ip

I get into the container

docker-compose exec webapp /bin/bash

and then checking the below command inside the container

ping host.docker.internal

it says

ping: host.docker.internal: Name or service not known

How to access host ip inside the container

I have to use host ip because i have to access the ssh tunnel on host

looks fine to me. `ping host.docker.internal` should usually return an astonishing timing < 2ms. No ports need to be exposed, you have always access to the host. How does the Dockerfile look like? — max, Mar 29 '23 at 07:14

I found the answer

in the docker-compose file had to add:

  webapp:
    image: "python3.10.10_custom_build:latest"
    extra_hosts:
      - "host.docker.internal:host-gateway"

and inside the container we can access

ping host-gateway
