[Ansible] vagrant 를 활용하여 ansible 실습 환경 구성

실습 환경

Ubuntu	18.04
VirtualBox	latest
Vagrant	latest

 

vagrant 설치는 이전 포스트 혹은 vagrant 공식 페이지에서 확인하시기 바랍니다.

 

 

실습 디렉토리 생성 및 이동

mkdir -p ~/vagrant/ansible && cd ~/vagrant/ansible

 

플러그인 설치

vagrant plugin install vagrant-hostmanager
vagrant plugin install vagrant-disksize
vagrant plugin list

vagrant box add ubuntu/bionic64
vagrant box list

 

 

vagrantfile 생성

$ cat Vagrantfile
