docker

개념 공부 및 실습

• https://training.play-with-docker.com/
  • 이 중 for Developer 실습으로 공부 하려 했으나 못함
• https://subicura.com/2017/01/19/docker-guide-for-beginners-1.html
  • 참고 블로그 (한글)

nCloud에 docker 설치

• https://docs.docker.com/install/linux/docker-ce/ubuntu
• 설치 중 참고

  • $ sudo apt-get install docker-ce=5:18.09.1~3-0~ubuntu-xenial docker-ce-cli=5:18.09.1~3-0~ubuntu-xenial containerd.io

    문서 중 'Install a specific version using the version string from the second column, for example'에서는 위와같이 입력해주면 된다.

  • OS requirements 중 Disco 19.04, Cosmic 18.10, Bionic 18.04 (LTS), Xenial 16.04 (LTS)들은 ubuntu version 들의 별칭이다.

해결해야할 것들

• volume 설정이 아쉽다. 정확하게 알아야함
• docker를 이용해 nCloud 서버에 mysql 서버 실행하기
  • lucas에 올라와있던 Mysql 설정등도 자동으로 적용하도록 Dockerfile을 만들어주면 좋을 것 같다.

기타

• docker ps 에서 ps? : process status의 약자. displays currently-running processes
  • https://en.wikipedia.org/wiki/Ps_(Unix)
• port : docker run -p 8080:80 name
  • -p [Host]:[Container]
  • 확인 : docker port name
• volume

  • version: '3'
      services:
        web:
          build: .
          ports:
            - "5000:5000"
          volumes:
            - .:/code
          environment:
            FLASK_ENV: development
        redis:
          image: "redis:alpine"
    

  • host의 . directory와 container의 /code directory 를 mount 한다.

  • volumes는 왜 필요한가?

    • 로컬에 뭔가를 저장할 필요가 있다고 하면 mount할 필요가 있다. 고 보면 될 것이다. (from 지수, almost 100% official)
    • Volumes are easier to back up or migrate than bind mounts.
    • In addition, volumes are often a better choice than persisting data in a container’s writable layer, because a volume does not increase the size of the containers using it, and the volume’s contents exist outside the lifecycle of a given container.
    • 참고 : https://docs.docker.com/compose/gettingstarted/#step-5-edit-the-compose-file-to-add-a-bind-mount

  • redis에서는 volume이 필요할까?

    • If persistence is enabled, data is stored in the VOLUME /data, which can be used with --volumes-from some-volume-container or -v /docker/host/dir:/data (see docs.docker volumes).
