Using database outside container

[visualcohol]

I'm trying to make a containerized Ghost instance on a Linux which uses the hosts database.

I tried to create an extra host in composer file, defining it as "database__connection__host" but after starting the container I get host error in logs. Tried to connect to host DB from a test Ubuntu container via host.docker.internal and worked flawlessly.

Did anybody encounter this scenario, and can point me in the right direction? tx

I think host.docker.internal is a Docker Desktop specific thing: 😅

$ docker run --rm tianon/network-toolbox dig host.docker.internal +short
$ 

Again on my DD-using Windows machine:

$ docker run --rm tianon/network-toolbox dig host.docker.internal +short
192.168.XX.YY
$ 

(I also see it in your extra_hosts, but I don't think that supports hostnames on the right-hand-side, so I hope that host-gateway is replaced with an actual IP address in your real file? 👀)
