Docker start container_id

  Docker run = Docker create + Docker start

Stop container and forcefully kill after 10 seconds

Docker stop containter_id

Without waiting kill container

Docker kill containter_id

Docker run extra command inside container. Can use exec/run

docker exec -it container_id command

Interacting with container command propmt

Build Dockerfile using

docker build .

. specify the build context or directory save location

Tagging the Docker Image (From Dockerfile)

docker_id / name : version

Also instead of specifying docker_id, passing name will work

Port Mapping

exporting port outside container

docker run -p 8080:8080 image_name

Docker compose

New build docker-compose up.

When change are made to file system run docker-compose up --build

By adding -d flag, container will start in background and keep on running

docker build -t friendlyhello .  # Create image using this directory's Dockerfile
docker run -p 4000:80 friendlyhello  # Run "friendlyhello" mapping port 4000 to 80
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

Dev and Production enviroment

Production -> Dockerfile Development -> Dockerfile.dev (Custom file extension name used for dev env) Command to run custom docker file docker build -f Dockerfile.dev .

Docker volumes

Connect local file to docker container files location. Files will sync as there are updated.

docker build -p 3000:3000 -v /app/node_modules -v $(pwd):/location_of_folder_in_docker image_id

To run test in docker container

docker run image_id npm run test
