Docker - 小筆記((整理中))

測試 Docker 是否安裝成功，
通常會使用 hello-world 來測試，
不過要注意的是，每下一次下面的指令，container 就會多一個

docker run hello-world

入門指令

## List Docker CLI commands
docker
docker container --help

## Display Docker version and info
docker --version
docker version
docker info

## Execute Docker image
docker run hello-world

## List Docker images
docker image ls

## List Docker containers (running, all, all in quiet mode)
docker container ls
docker container ls --all
docker container ls -aq

docker run

• -d background 執行
• -p [docker port]:[外部 prot] 指定 port 對應

docker run -d -p 4000:80 friendlyhello

docker container

• ls 列出 container

$ docker container ls
CONTAINER ID        IMAGE               COMMAND             CREATED
1fa4ab2cf395        friendlyhello       "python app.py"     28 seconds ago

• stop [container id] 停止指定的 container

docker container stop 1fa4ab2cf395

docker images

• 列出 images

$ docker images

REPOSITORY               TAG                 IMAGE ID            CREATED             SIZE
friendlyhello            latest              d9e555c53008        3 minutes ago       195MB
gordon/get-started         part2               d9e555c53008        3 minutes ago       195MB

...

• 等同 docker image ls

$ docker image ls

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
