The reason for using Docker is used to define and start running multi-container Docker applications. It is very easy to configure Docker, there would be YAML file to configure your application’s services/networks/volumes etc., Then, with a single command, you can create and start all the services from the compose configuration.
Here are some key steps that you must follow:-
You need to define Dockerfile for your app’s environment.
You need to define docker-compose.yml for the services that make up your app services.
You should run docker-compose up and Compose starts and runs your entire app.
