세상의 모든 데이터

목표 : docker 컨테이너에 ubuntu를 받고 이것 저것 만져본다.
어디서 : 우분투, cmd 등 프로그램에서
어떻게: 리눅스 명령어를 입력해서

리눅스 커널과 배포판

• 배포판의 종류 
  우분투, 데비안, 알파인, 페도라, 센트os 등등
• 배포판에 따른 패키지 매니저
  파이썬 : 우분투(apt, pip) , 데비안 (apt, pip), 알파인리눅스 (apt, pip), 페도라(dnf,pip), 센트os(yum,pip), 
  JavaScript(Node.js)  : npm, yarn
  C# 등의 언어 : NuGut
  
  

실습(진한글씨만 입력하는것)

• 우분투를 실행 (로컬에 없기 때문에 알아서 다운받는다)
  weare@DESKTOP-BE1I4GE:~$ docker run ubuntu
  Unable to find image 'ubuntu:latest' locally
  latest: Pulling from library/ubuntu
  a48641193673: Pull complete
  Digest: sha256:6042500cf4b44023ea1894effe7890666b0c5c7871ed83a97c36c76ae560bb9b
  Status: Downloaded newer image for ubuntu:latest
  unable to upgrade to tcp, received 404
  
  
• 도커컨테이너 목록중에 우분투가 실행되는지 확인
  weare@DESKTOP-BE1I4GE:~$ docker ps
  CONTAINER ID   IMAGE                  COMMAND                  CREATED        STATUS                      PORTS                    NAMES
  실행 안된다. 그 이유는 동작완료하고 동작을 유지하지 않았기 때문
  
  
•  -a를 추가해 완료된 도커 컨테이너도 확인
  weare@DESKTOP-BE1I4GE:~$ docker ps -a
