namespace: nginx
containers:

  # "shared" is the data volume container that holds nginx config files and static html files for
  # the "nginx" container. It is empty from the beginning, but once "configs" container is started
  # files are copied to the "shared" container with rsync(1)
  # 
  # This container is designed to be persistent across deploys of both "nginx" and "configs"
  # containers.
