L'idée de ce script est de générer à la demande un fichier hosts pouvant être utilisé par Ansible contenant l'inventaire des serveurs gérés par spacewalk.

Le fichier de config :
/usr/local/etc/spacewalk-api.conf
[main]
SATELLITE_URL = http://spacewalk/rpc/api
SATELLITE_LOGIN = user
SATELLITE_PASSWORD = cGFzc3dvcmQ=
Vous pouvez cronner la génération du fichier pour avoir un inventaire à jour.
Il est alors possible de lancer des commandes ansibles sur les groupes spacewalk.
Exemple:
uptime des serveurs RHEL7 de dev :
root@ansible-server: (~)# ansible "RHEL7:&DEV" -a uptime
Et voilà
