理解differences between docker vs. docker-compose

• docker

  The docker cli is used when managing individual containers on a docker engine.

  It is the client command line to access the docker daemon api.

• docker-compose

  The docker-compose cli can be used to manage a multi-container application.

  It also moves many of the options you would enter on the docker run cli into the docker-compose.yml file for easier reuse.

  It works as a front end “script” on top of the same docker api used by docker, so you can do everything docker-compose does with docker commands and a lot of shell scripting.
