CI/CD Inter-Service Networking

GitLab CI/CD
6

Hi @Progdrasil,

I am trying to get inter-service networking to work. However, even with setting the FF_NETWORK_PER_BUILD variable, the service containers are not able to reach another service container.

Any ideas on what I might be doing wrong?

I am still getting this error when backend tries to ensure database is up and running:

2020-12-31T11:30:44.710149815Z Ncat: Could not resolve hostname "database": Name or service not known. QUITTING.`

Thank you for your time and help :slight_smile:

Here’s the code in case it is easier than the link:
