Thanks !
1/ Ok so i configured my 3 environments in group/vars. I edit the main.yml after a bug (thread)
So now, i have an error with composer when i vagrant up :
==> default: stderr: Composer could not find a composer.json file in /srv/www/mydomain/current
==> default: To initialize a project, please create a composer.json file as desc
ribed in the https://getcomposer.org/ “Getting Started” section
==> default:
==> default: FATAL: all hosts have already failed – aborting
==> default: PLAY RECAP ********************************************************
==> default: to retry, use: --limit @/root/dev.retry
==> default:
==> default: 127.0.0.1 : ok=70 changed=39 unreachable=0
failed=1
How can i resolve this error ?
2/ Stupid question : Ansible need to be installed on my virtualbox environment right ? Not on windows, like vagrant ?
EDIT : Ok i saw Ansible need to be installed on my windows like Vagrant, but there is no windows client right now. I saw a lot of threads who people says, “you can run ansible with Cygwin (or Babun) but It’s not a good solution !”. So… What is the solution for windows users ? I hope i’m not the only windows user on this forum 
!
Thanks for your help !
