In my pipelines I have defined an external service that runs Postgres:
Now, in my pipeline I need to build my web app from a custom Dockerfile and then test it with the DB. So I define my pipeline step as follows:
- docker build -t app .
- docker run app ./run_tests.sh

I also tried to run it with `--network="host"` but this doesn't work due to restrictions in place.
Any ideas? In GitLab this works perfectly. Thanks.
Try adding a host-to-IP mapping in your "docker run" command, like this:
docker run --add-host host.docker.internal:$BITBUCKET_DOCKER_HOST_INTERNAL app ./run_tests.sh
Then you should be able to connect to the service using host.docker.internal:5432 within the container.
