What are the three main steps of Docker Compose?

Three main steps of Docker Compose are as follows:

  • Environment: We first define the environment of our application with a Dockerfile. It can be used to recreate the environment at a later point of time.

  • Run: The last step is to run the Docker Container. We use docker-compose up to start and run the application.
