Les nouveautés d'Ansible 4.0

Après la version 3.0, qui a marqué le changement de packaging d’Ansible, voici la version 4.0. Comme annoncé, elle est basée sur Ansible-base 2.11 et contient toute une série de mises à jour sur les collections incluses. Vous pouvez retrouver la liste complète ici :

CHANGELOG-v4 ↗

Si on parcourt la liste des changements, on remarque que beaucoup de ménage a été fait dans les modules. Donc faites attention lors de la migration, car certains de vos rôles ou playbooks risquent de ne plus fonctionner !

Ansible-test a beaucoup évolué et supporte beaucoup plus de systèmes d’exploitation qu’auparavant (RHEL 8.3, MacOS 11.1, …)

Comment Installer Ansible 4.0.0

Attention si vous avez déjà installé ansible avec pip, il faudra la désinstaller en premier. De plus, python 3.8 est requis sur le node controller d’Ansible.

*Upgrading directly from ansible-2.10, ansible-3, or ansible-base-2.10 to ansible-4*
*or greater with pip is known to cause problems.  Please uninstall the old version ... *

Comment procéder ?

pip3 uninstall ansible
pip3 install ansible
