Add this to the service in your docker-compose.yml

  extra_hosts:
     - host.docker.internal:host-gateway

Example:

services:
    redis:
    restart: always
    container_name: redis
    image: redis:7.2-alpine
    extra_hosts:
      - host.docker.internal:host-gateway

Then you can reach your host from inside the container via host.docker.internal:3434

host.docker.internal is like your “localhost” on the host. It is a special DNS name.

You have a lot of options: https://docs.docker.com/network/drivers/

What’s specifically the issue with the host driver in this case?

Have you tried the IP of the host? IIRC that should work.

Put them on the same network

My solution is to create a docker network with the macvlan driver connected to a bridge interface on the host. Then you make the database listen on the bridge or just leave it on all interfaces. Don’t forget to configure the ips.

I can share my config later.

You can use the flag

–add-host myname=host-gateway

in your container “myname” will resolve as the IP of your host.
