Title: Docker Compose Environment Variable Resolution Examples

Summary

A table illustrating how Docker Compose resolves environment variables (`VALUE`) based on precedence. The table considers settings from `docker compose run`, `environment` attribute, `env_file` attribute, Image `ENV`, host OS environment, and `.env` files. The "Result" column indicates the final value of `VALUE` based on which source takes precedence in each scenario.
