[Docker] 도커 실습 (1) - 서버 셋팅

도커 실습을 위해 ubuntu 서버를 셋팅한다.

서버 셋팅은 VMware Workstation 16 Player 와 ubuntu-18.04.5-live-server-amd64.iso 를 각각 설치해서 셋팅을 진행했다.

• vmware 설치 : https://www.vmware.com/kr/products/workstation-player/workstation-player-evaluation.html
• ubuntu 설치 : https://mirror.kakao.com/ubuntu-releases/bionic/

vnware 및 ubuntu 설치

1. vmware를 설치하고 실행한다.
   

   

2. 동의 후 next
   

   

3. 기본 설정 후 next
   

   

4. Check for product updates on startup : 시작시 Tool의 업데이트를 확인
   Join the VMware Customer Experience Improvement Program : 사용자 체험 개선 프로그램 참여
   난 둘다 check 하지 않고 next
   

   

5. 다음 next
   

   

6. install 을 눌러 설치를 시작한다.
   

   

7. 설치 완료
   

   

8. workstation 을 실행한다. 나는 무료 버전이기 때문에 key 입력없이 next
   

   

9. finish
   

   

10. 첫 시작 화면에서 이제 실습한 서버를 만들기 위해 Create a New Virtual Machine 을 클릭한다.
    

    

11. 아까 설치한 ubuntu iso 파일을 등록한다. ( 알집 푸는 거 아니다!! )
    

    

12. 서버에 로그인할 계정을 설정한다. ( 잊어버리지 말기 )
    

    

13. next
    

    

14. 실습은 20GB 면 충분하니 그대로 NEXT
    

    

15. ubuntu 서버가 생성되었다. finish
    

    

16. 이제 workstation 시작화면에서 만들어진 ubuntu 서버를 실행한다. 근데 이 화면서 오류가 나는 경우가 있고, 나도 오류가 발생해서 해결해주었다. - 오류 해결 방법
    

    

17. 위에서 오류를 해결하고 나면 설치가 진행이 된다.
    

    

18. 언어 설정. 우리가 가장 익숙한 English를 선택한다. 참 나는 가상머신을 처음 사용해서 클릭을 어떻게 하는 지 몰랐는데 마우스로도 안되고 방향키로도 안되었었다..,,, ㅋㅋㅋㅋㅋ ctrl + G 는 가성머신에 활설화 시키는 단축키이니 단축키를 누르고 방향키로 이동하면서 조작이 가능.
    

    

19. 난 없데이트 없이 진행
    

    

20. 영어 Done
    

    

21. 이 화면은 ubuntu에 있는 package를 받아오는 mirror 서버는 보통 속도가 빠른 kakao mirror 서버를 이용한다.
    

    

22. 아까 입력한 서버계정을 동일하게 입력해준다.
    

    

23. 설치 진행 ( 중간 중간에 올리지 않은 화면도 있는데 그 부분들은 별도의 변경내역이 없어서 생략했다. 각각에 맞추어 변경할 내용있다면 적용하면 될 것 같다. )
    

    

24. 설치가 진행이 되면 업데이트를 취소하고 리붓한다는 내용이 활성화 되는데 여기서 좀 더 기다리면 업데이트가 완료된다.
    (PC 사양에 따라 조금 다른데 나는 15분..? 정도 기다린 것 같다. 보통 5분?)
    

    

25. Reboot!
    

    

26. 정상적으로 Reboot이 진행되고 enter키를 누르면 계정을 입력하라는 문구가 나온다.
    

    

27. 계정을 입력하고 나면 이제 정상적으로 도커를 실습하기 위한 서버로 연결이 되었다.

    

Docker 설치

Docker를 설치한다!

Docker Docs 를 참고하면 쉽게 설치할 수 있다.
