SUMMARY

Have an ansible-requirements.txt file to install necessary python modules during build time. The proxy settings in the container.yml are not being passed as build-arguments to the downstream container build. This is necessary because we need to set http_proxy, no_proxy, and https_proxy in order to do these external builds. The builds are failing because it is unable to reach the external network because the necessary environment variables are not being passed back to the downstream build.

    environment:  # List or mapping of environment variables
      - DISTRO=bionic
      - TYPE=lamp

This is how I am using ENV vars. They are then successfully seen by ansible roles.
