Summary
Environment variables can be used to configure Docker images and dockerized apps. ARG and ENV variables can be used to set environment variables, and env_files can be used to pass many environment variables to a single command in one batch. Docker-compose templating can also be used to set environment variables. Additionally, environment variables can be used to keep confidential information confidential, organize confidential information in one file, and reuse env files in multiple containers.
