[Docker] 도커 환경설정

도커 환경 구성

가성머신 설치

• 리눅스 - centos 7버전 이상 / ubuntu 18.04 ~ 22.x 버전 이상 사용
• Ubuntu Bionic 18.04 (LTS)
• https://docs.docker.com/engine/install/ubuntu/
• https://www.virtualbox.org/wiki/Download_Old_Builds - virtualbox 다운로드
• https://hub.docker.com/

vagrant 설치

• https://www.vagrantup.com/ => AMD64 다운로드
• 다운로드 후 버전 확인

vagrant image 를 활용하여 docker 설치
mswindow 에서 powershell 실행후
임의의 디렉토리 생성후 아래처럼 파일 다운로드

wget http://twoseven.kr/weekend_0218/docker_vm/Vagrantfile -Outfile Vagrantfile
wget http://twoseven.kr/weekend_0218/docker_vm/docker_install.sh -Outfile docker_install.sh
wget http://twoseven.kr/weekend_0218/docker_vm/ssh_conf.sh -Outfile ssh_conf.sh

그다음 파일을 다운로드 받은 디렉토리 안에서 vagrant up 실행

C:\WINDOWS\system32> vagrant version 

• cpu 가상화가 bios에서 켜져있어야됨
• cmos setup

vagarnt에서는 box https://app.vagrantup.com/boxes/search?utf8=%E2%9C%93&sort=downloads&provider=&q=ubuntu22
