exécution ansible PlayBook AttributeError: objet 'str' n'a pas d'attribut 'set_playbook_basedir'

Question

Bonjour,

J'ai une question en deux parties.

Première partie: Je suis en train d'exécuter un PlayBook à partir d'un script python qui télécharge un livre de jeu et l'exécute. Je sais que le playbook fonctionne parce que je l'ai testé. Cependant, quand j'essaie d'exécuter le playbook avec du code python, j'obtiens un sans erreur d'attribut 'set_playbook_basedir' pas très sûr d'où cela vient. Voici la sortie d'erreur complète.

[ec2-user@ip-172-30-199-190 scripts]$ sudo python /var/lib/cloud/instance/scripts/part-001

           callbacks = playbook_cb, 
           runner_callbacks = runner_cb, 
           inventory = "localhost", 
           check=True) 
# running the playbook 
pr = pb.run() 

# print the summary of results for each host 
#print json.dumps(pr, sort_keys=True, indent=4, separators=(',', ': ')) 

Le deuxième problème est:

Ce script est réellement passé comme les SSFE codé en base64 données utilisateur et son exécution, mais il ne semble pas reconnaître qu'il est python. Voici la-init-output.log nuage

Je ne peux pas reproduire vos problèmes, mais ma meilleure estimation est que:

1) Vous devez initialiser votre PlayBook avec un objet d'inventaire au lieu de une chaîne:

from ansible.inventory import Inventory 
pb = PlayBook(playbook = full_path, 
       stats = stats, 
       callbacks = playbook_cb, 
       runner_callbacks = runner_cb, 
       inventory = Inventory(["localhost"]), 
       check=True) 

2) Votre script python doit être préfixé avec indication bash qu'il doit être exécuté par python. Il suffit de mettre le shebang suivant en haut de votre script python:

#! /usr/bin/env python 

Vous pouvez également exécuter votre script avec:

python /var/lib/cloud/instance/scripts/part-001 

au lieu de simplement:

/var/lib/cloud/instance/scripts/part-001
