Windows에서 WSL2/Vagrant/VBox로 Ansible 실습

read

개요

WSL2에 Vagrant를 설치하여 호스트에 설치된 virtualbox을 활용하여 VM 생성/구성/관리 가능

윈도우에는 ansible control 서버를 설치 할 수 없어 ansible provisioner를 사용할 수 없음
vagrant에서 ansible/ansible_local 지원
- ansible, where Ansible is executed on the Vagrant host
- ansible_local, where Ansible is executed on the Vagrant guest
ansible provioner는 호스트에 asnible 설치, ansible_local는 guest에 ansible 설치 따라서 window host에서는 ansible_local 사용
참고

사전 설치

호스트 vagrant(windows 10)와 WSL2 vagrant 버전 통일

NOTE: When Vagrant is installed on the Windows system the version installed within the Linux distribution must match.’

에러 메세지

  The provider 'virtualbox' that was requested to back the machine 'default' is reporting that it isn't usable on this system. The reason is shown below:
    			
  VirtualBox is complaining that the kernel module is not loaded. Please
  run `VBoxManage --version` or open the VirtualBox GUI to see the error
  message which should contain instructions on how to fix this error.

WSL2 vagrant 삭제후 재 설치

  Timed out while waiting for the machine to boot. This means that
  Vagrant was unable to communicate with the guest machine within
  the configured ("config.vm.boot_timeout" value) time period.If you look above, you should be able to see the error(s) that
  Vagrant had when attempting to connect to the machine. These errors
  are usually good hints as to what may be wrong.If you're using a custom box, make sure that networking is properly
  working and you're able to connect to the machine. It is a common
  problem that networking isn't setup properly in these boxes.
  Verify that authentication configurations are also setup properly,
  as well.If the box appears to be booting properly, you may want to increase
  the timeout ("config.vm.boot_timeout") value.

config.vm.provision “ansible_local”

config.vm.provision = ansible로 할경우 호스트 즉 windows10에 ansible을 설치 하라는 에러가 발생함. Windows10에서는 ansible을 설치 할 수 없으므로 ansible_local로 provision 해야 함

The Ansible software could not be found! Please verify
that Ansible is correctly installed on your host system.

If you haven't installed Ansible yet, please install Ansible
on your host system. Vagrant can't do this for you in a safe and
automated way.
Please check https://docs.ansible.com for more information.

synced folder : config.vm.synced_folder ‘.’, ‘/vagrant’

ansible_local provision을 할 경우 playbook이 호스와 게스트 공유폴더를 통해 공유 되어야 함
