Ansible: Wie kann ich eine Datei löschen/neu erstellen, während Ansible Playbook ausgeführt wird?
Veröffentlicht: 2019-08-29Ansible ist zweifellos das beste Tool zur Infrastrukturautomatisierung, das von den führenden Fortune-500-Unternehmen weltweit verwendet wird.
Auf Crunchify haben wir eine Vielzahl von Tutorials zu Ansible veröffentlicht. Bitte werfen Sie einen Blick auf Ansible Archive für alle detaillierten Tutorials. Hier sind die Top-3-Tutorials.
- Wie kopiert man Dateien, Verzeichnisse oder Skripte vom lokalen Host auf den Remote-Host?
- Wie erstellt man Amazon EC2-VMs mit Ansible?
- Wie führe ich Befehle auf Remote-Hosts aus und erhalte das Befehlsergebnis (Protokoll) zurück?
In diesem Tutorial gehen wir auf 3 verschiedene Tipps ein, die ich täglich verwende.
Wie kann ich eine Datei mit Ansible löschen und neu erstellen?
Schritt 1
Stellen Sie sicher, dass Sie Ansible auf Ihrem Mac oder Linux-Betriebssystem korrekt eingerichtet haben.
Schritt 2
Erstellen Sie die Datei 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 |
Schritt 3
Öffnen hosts
-Datei und fügen Sie den folgenden Inhalt ein:
1 2 |
[ local ] localhost ansible_connection = local ansible_python_interpreter = python |
Schritt 4
Führen Sie Ansible playbook
.
1 |
ansible - playbook - vvv - i . / hosts crunchify - delete - recreate - ansible . yml |
Hier ist ein Ergebnis:

Und das ist es. Das obige Ansible-Playbook löscht eine vorhandene Datei mit dem Namen crunchify.txt
und erstellt eine neue mit leerem Inhalt.

Teilen Sie uns wie üblich jede Frage oder jedes Problem mit, das über Ansible Playbook ausgeführt wird.
