Django test database fails in circleci

Build Environment Databases
1

I have a Django Postgres project that I am deploying with docker-compose, it runs and all the test pass in every environment, but the tests for some reason fail in circleci. There is some issue with django creating a test database that seems to fail in circleci and I don’t know enough about circleci and docker to resolve.

# circle.yml
machine:
  services:
    - docker

dependencies:
  pre:
    - pip install docker-compose

test:
  pre:
    - docker-compose up -d
  override:
    - docker-compose run web python manage.py test

error in circleci:

django.db.utils.OperationalError: FATAL:  no pg_hba.conf entry for host "172.18.0.4", user "docker", database "postgres", SSL on
