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 -aqdocker run
- -d background 執行
- -p [docker port]:[外部 prot] 指定 port 對應
docker run -d -p 4000:80 friendlyhellodocker 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 1fa4ab2cf395docker images
- 列出 images
$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE

...- 等同 docker image ls
$ docker image lsdocker 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參考
