Here are some basic commands used in docker. Hope it helps you.

• Create a docker file : create a file named Dockerfile in the folder.
• Create docker image : Execute command in the directory containing Dockerfile: docker build -t image_tag_name .
  • [.] indicated the current folder where file named Dockerfile is
• List all docker images:
  • docker images
• Run docker image : docker run -it --name container_name_here image_tag_name
  • -it: It will open interactive terminal after running it, to interact with container
• To connect to running container: docker exec -it container_name shell[/bin/bash]
  • E.g docker exec -it debian /bin/bash
• Start any stopped container:
  • Just start the container: docker start container_name
  • Start container and connect: docker start -i container_name

• List all container: docker ps -a

• List all running container: docker ps

• Find ip address of running container:
  • docker inspect container_name| grep IPAddress

• Renaming the docker : docker rename old_container_name new_container_name

• Remove
  • Container : docker rm -f container_name
    • Running container need to be stopped first, then removed. To do it forcefully use -f flag.
    • All stopped containers : docker rm $(docker ps --filter "status=exited" -q)
  • Image : docker rmi image_name
• Container to host port connection
  • docker run -p <host_port>:<container_port> -p <host_port>:<container_port> -d -it --name container_name image-name
