Docker compose uses the Dockerfile if you add the build command to your project's docker-compose. yml. Your Docker workflow should be to build a suitable Dockerfile for each image you wish to create, then use compose to assemble the images using the build command.

A Dockerfile is a text document with a series of commands used to build a Docker image. Docker Compose is a tool for defining and running multi-container applications.
