Ansible: come accettare l'input dell'utente utilizzando vars_prompt e la riga di comando?
Pubblicato: 2020-06-08
Sono passati alcuni mesi che ho iniziato a suonare con Ansible. In questo tutorial, esamineremo come utilizzare vars_prompt ansible section se desideri prompt the user un determinato input durante l'esecuzione di ansible playbook.
Iniziamo:
Passo 1
Crea il file hosts e mettilo nella cartella chiamata /Users/Shared/ansible .
|
1 2 3 4 5 6 7 8 |
[ local ] localhost ansible_connection = local ansible_python_interpreter = python [ defaults ] host_key_checking = false [ crunchify ] localhost |
Passo 2
Metti il tuo file ansible.cfg predefinito nella stessa cartella.
|
1 2 3 4 |
[ defaults ] ansible_ssh_user = crunchify inventory = hosts host_key_checking = false |
Passaggio 3
Crea il file crunchify.yml in cui useremo la sezione vars_prompt per ottenere l'input dell'utente.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 |
--- - hosts : crunchify connection : local vars_prompt : - name : website prompt : "What is your website?" private : no - name : country prompt : "Enter Country Name?" private : no tasks : - debug : msg : 'Website name: {{ website }}. Country name: {{ country }}' |
Passaggio 4
Esegui un playbook ansible.
|
1 2 3 4 |
bash - 3.2 $ pwd / Users / Shared / ansible bash - 3.2 $ ansible - playbook - vvv crunchify . yml |
Output della console di pagamento:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 |

Come saltare il prompt dell'utente e accettare argomenti tramite riga di comando:
|
1 |
bash - 3.2 $ ansible - playbook - vvv crunchify . yml - e "website='Crunchify.com' country='United States'" |
Facci sapere se riscontri problemi durante l'esecuzione dello script ansible.
