2. sudo apt-get install libsecret-1-0 libsecret-1-dev
3. cd /usr/share/doc/git/contrib/credential/libsecret
4. sudo make
5. git config --global credential.helper /usr/share/doc/git/contrib/credential/libsecret/git-credential-libsecret

# GitLab uses docker in the background, so we need to specify the 
# image versions. This is useful because we're freely to use
# multiple node versions to work with it. They come from the docker
# repo.
# Uses NodeJS V 9.4.0
image: node:9.4.0

# And to cache them as well.

You have to do 2 things in order to allow your container to access your host's postgresql database

1. Make your postgresql listen to an external ip address
2. Let this client ip (your docker container) access your postgresql database with a given user

Obs: By "Host" here I mean "the server where docker is running on".

Make your postgresql listen to an external ip address

Find your postgresql.conf (in case you don't know where it is)

$ sudo find / -type f -name postgresql.conf
