🟢 도커코드 실행

🔹 코드 명령어 & 설명
🟩 Orientation and set-up

## 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
```　

🟩 Containers

```Linux
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
```　

🟩 Start-위의 코드 설명

```Linux
# 도커라고 타이핑 후, 옵션을 넣고 commands를 해라~ (옵션을 부가적인 것으로 들어갈수도있고 들어가지 않을수도있음) 
docker 
# 도커야, 컨테이너를 제어하는 command를 실행해
docker container --help
# 도커야, List containers를 실행해
docker container ls

# 도커버전 확인 (버전: 20.10.13)
docker --version
# 도커안에있는 풀세트가 나옴 (Client; Cloud integration version, Server, OS/Arch 등)
docker version 
# 내가 만든 프로그램이 어떻게 돌아가고 있는지 확인 (Stopped: 7개이고, 이미지 2개, 버전은 20.10.13
docker info 

## Unable to find image 'hello-world:latest' locally
# 도커 런을 했기에 도커허브에서 이미지를 가져온거고, 그 이미지를 가지고 런을 했다는 의미
docker run hello-world

# help
docker image --help
# 이미지에는 hello-world, alpine/git, docker/getting-started가 있음
docker image ls

# 컨테이너 확인
## 결과) List containers가 존재
docker container –help

# 결과 아무것도 없음 --> 없는 이유 : hello-world는 실행되면 나감
docker container ls

# stop된 모든 것을 보고싶을 때, all 사용
## 결과) hello-world 많음
docker container ls –all
```
