Docker Pull을 이용해 도커 이미지 갖고 오기

root@coforward:/home/coforward# docker pull ubuntu:latest

 

이미지 확인

docker images

root@coforward:/home/coforward# docker images
REPOSITORY    TAG       IMAGE ID       CREATED        SIZE
ubuntu        latest    5a81c4b8502e   5 weeks ago    77.8MB
hello-world   latest    9c7a54a9a43c   3 months ago   13.3kB

docker pull 명령어는 docker hub에 있는 이미지를 받아서 build까지 수행

 

 

현재는 이미지가 빌드 되어 있는 상태이고 컨테이너로 만들어서 실행을 시킨다.

docker run -t [REPOSITORY]

root@coforward:/home/coforward# docker run -t ubuntu
root@0b508f68aea2:/#

 

포워포트딩으로 실행 할경우

docker run -it -d --name [NAMES] -p <host port number>:<container port number>/<protocol> [IMAGE NAME] [OTHER OPTIONS...]

프로세를 확인하면 Status에 도커가 실행된 것을 확인할수 있다

root@coforward:/home/coforward# docker ps -a
