sudo docker exec -it <container_id> bash

• Stop a Docker container:-

sudo docker stop <container_id>

• Delete a Docker container:-

• Delete a Docker image:-

sudo docker rmi <image_id>

• Removing all Images:-

Networking:-

• Creating a Bridge Network:-

• Creating an Overlay Network:-

docker network create -d overlay MyOverlayNetwork

• Creating a Customized Overlay Network:-

docker network create -d overlay \
--subnet=192.168.0.0/16 \
--subnet=192.170.0.0/16 \
--gateway=192.168.0.100 \
--gateway=192.170.0.100 \
--ip-range=192.168.1.0/24 \
--aux-address="my-router=192.168.1.5" --aux-address="my-switch=192.168.1.6" \
--aux-address="my-printer=192.170.1.5" --aux-address="my-nas=192.170.1.6" \
MyOverlayNetwork

• Removing a Network:-

docker network rm MyOverlayNetwork

• Listing Networks:-

docker network ls

• Getting Information About a Network:-

    docker network inspect MyOverlayNetwork
  

• Connecting a Running Container to a Network:-

docker network connect MyOverlayNetwork nginx

• Connecting a Container to a Network When it Starts:-

docker container run -it -d --network=MyOverlayNetwork nginx

• Disconnecting a Container from a Network:-

docker network disconnect MyOverlayNetwork nginx

Volume:-

• Create a new Docker volume:-

     docker volume create <volume_name>
  

• List Docker volumes.:-

docker volume ls

• Inspect details about a Docker volume:-

     docker volume inspect <volume_name>
  

• Remove a Docker volume:-

     docker volume rm <volume_name>

• Stop and remove containers defined in a Docker Compose file:-

docker-compose down

DOCKER HUB:-

• Login into Docker:-

docker login -u <username>
