# https://docs.docker.com/compose/environment-variables/env-file/#parameter-expansion
# https://docs.docker.com/compose/environment-variables/envvars-precedence/
#
# The order of precedence (highest to lowest) is as follows:
#
# 1. Set using docker compose run -e in the CLI
# 2. Substituted from your shell
# 3. Set using the environment attribute in the Compose file
# 4. Use of the --env-file argument in the CLI
# 5. Use of the env_file attribute in the Compose file
# 6. Set using an .env file placed at base of your project directory
# 7. Set in a container image in the ENV directive. Having any ARG or ENV setting in a
#      Dockerfile evaluates only if there is no Docker Compose entry for environment,
#      env_file or run --env.
