Docker Command Sumamry

We will go over these fundamental commands:

docker build -t friendlyhello .  # Create image using this directory's Dockerfile  
docker run -d -p 4000:80 friendlyhello         # Same thing, but in detached mode  
docker container ls                                # List all running containers  
docker container ls -a             # List all containers, even those not running  
docker container stop <hash>           # Gracefully stop the specified container  
docker container kill <hash>         # Force shutdown of the specified container  
docker container rm <hash>        # Remove specified container from this machine  
docker container rm $(docker container ls -a -q)         # Remove all containers  
docker image ls -a                             # List all images on this machine  
docker image rm <image id>            # Remove specified image from this machine  
docker image rm $(docker image ls -a -q)   # Remove all images from this machine  
docker login             # Log in this CLI session using your Docker credentials  
docker tag <image> username/repository:tag  # Tag <image> for upload to registry  
docker push username/repository:tag            # Upload tagged image to registry  
docker run username/repository:tag                   # Run image from a registry

Detach from container and leave running

<cntrl p+q>

docker tag bbearce/docker_demo:from_docker_file bbearce/docker_demo:delete_me

Login to your dockerhub account

docker login --username=bbearce

To push image online

docker push bbearce/docker_demo:from_docker_file

To automatically remove container when exited

docker run -it --rm --name=auto_remove bbearce/docker_demo:from_docker_file bash

Use bash flag -v : to mount the host folder inside the docker.

docker run -it --rm --name=auto_remove -v /home/bbearce/Desktop/Docker_Demo/mount:/app bbearce/docker_demo:from_docker_file bash
