Ansible : comment supprimer/recréer un fichier lors de l'exécution d'Ansible Playbook ?
Publié: 2019-08-29Ansible est sans aucun doute le meilleur outil d'automatisation d'infrastructure qui est utilisé par les 500 plus grandes entreprises du monde.
Sur Crunchify, nous avons publié une grande variété de tutoriels sur Ansible. Veuillez consulter Ansible Archive pour tous les tutoriels détaillés. Voici les 3 meilleurs tutoriels.
- Comment copier un fichier, un répertoire ou un script de localhost vers un hôte distant ?
- Comment générer des machines virtuelles Amazon EC2 à l'aide d'Ansible ?
- Comment exécuter des commandes sur des hôtes distants et récupérer le résultat de la commande (journal) ?
Dans ce tutoriel, nous allons passer en revue 3 astuces différentes que j'utilise au quotidien.
Comment supprimer et recréer un fichier avec Ansible ?
Étape 1
Assurez-vous d'avoir correctement configuré Ansible sur votre système d'exploitation Mac ou Linux.
Étape 2
Créer le fichier crunchify-delete-recreate-ansible.yml
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
--- - name : Delete and Re - Create crunchify . txt file from current directory . hosts : local connection : local gather_facts : True tasks : - name : delete file ignore_errors : yes file : state : absent path : crunchify . txt - name : Ansible create file if it doesn ' t exist example ignore_errors : yes file : path : "crunchify.txt" state : touch |
Étape 3
Ouvrez le fichier hosts
et mettez le contenu ci-dessous :
1 2 |
[ local ] localhost ansible_connection = local ansible_python_interpreter = python |
Étape 4
Exécutez Ansible playbook
.
1 |
ansible - playbook - vvv - i . / hosts crunchify - delete - recreate - ansible . yml |
Voici un résultat :

Et c'est tout. Ci-dessus, Ansible playbook supprimera un fichier existant nommé crunchify.txt
et en créera un nouveau avec un contenu vide.

Comme d'habitude, faites-nous savoir pour toute requête ou tout problème d'exécution au-dessus d'Ansible Playbook.
