#webdev #docker #python #beginners

Compose simplifies the control of your entire application stack, making it easy to manage services, networks, and volumes in a single, comprehensible YAML configuration file. Then, with a single command, you create and start all the services from your configuration file

docker image rm <image-name> -f delete image which is in use forcefully
docker ps -a to see all the containers running
