Ansible - Come eliminare Ricreare un file?

Ansible senza dubbio il miglior strumento di automazione delle infrastrutture in circolazione, utilizzato dalle migliori aziende Fortune 500 in tutto il mondo.

Su Crunchify, abbiamo pubblicato una vasta gamma di tutorial su Ansible. Si prega di dare un'occhiata a Ansible Archive per tutti i tutorial dettagliati. Ecco i 3 migliori tutorial.

  1. Come copiare file, directory o script da localhost a host remoto?
  2. Come generare VM Amazon EC2 utilizzando Ansible?
  3. Come eseguire comandi su host remoti e recuperare il risultato del comando (registro)?

In questo tutorial esamineremo 3 diversi suggerimenti che utilizzo quotidianamente.

Come eliminare e ricreare un file utilizzando Ansible?

PLAY RECAP * ****************************************************************************************************************************************************
localhost                    : ok = 3      changed = 2      unreachable = 0      failed = 0

E questo è tutto. Sopra il playbook di Ansible eliminerà un file esistente chiamato crunchify.txt e ne creerà uno nuovo con contenuto vuoto.

Come al solito, faccelo sapere per qualsiasi domanda o problema in esecuzione su Ansible Playbook.
