How to use docker for multiple application environments

Question - How to use docker for multiple application environments?

Answer -

Docker-compose feature of docker will come to help here. In the docker-compose file, we can define multiple services, networks, and containers along with the volume mapping in a clean manner, and then we can just call the command “docker-compose up”.
When there are multiple environments involved - it can be either dev, staging, uat, or production servers, we would want to define the server-specific dependencies and processes for running the application. In this case, we can go ahead with creating environment-specific docker-compose files of the name “docker-compose.{environment}.yml” and then based on the environment, we can set up and run the application.
