=======
|
||
|
||
When running a playbook, you may wish to prompt the user for certain input, and can
|
||
do so with the 'vars_prompt' section.
|
||
|
||
A common use for this might be for asking for sensitive data that you do not want to record.
|
||
|
||
This has uses beyond security, for instance, you may use the same playbook for all
|
||
software releases and would prompt for a particular release version
|
||
in a push-script.
|
||
|
||
Here is a most basic example::
|
||
|
||
---
|
||
- hosts: all
|
||
remote_user: root
|
||
|
||
vars:
|
||
from: "camelot"
|
||
|
||
vars_prompt:
|
||
name: "what is your name?"
|
||
quest: "what is your quest?"
|
||
favcolor: "what is your favorite color?"
|
||
|
||
If you have a variable that changes infrequently, it might make sense to
|
||
provide a default value that can be overridden. This can be accomplished using
|
||
the default argument::
|
||
|
||
vars_prompt:
|
||
|
||
- name: "release_version"
|
||
prompt: "Product release version"
|
||
default: "1.0"
|
||
|
||
An alternative form of vars_prompt allows for hiding input from the user, and may later support
|
||
some other options, but otherwise works equivalently::
|
||
|
||
vars_prompt:
|
||
|
||
- name: "some_password"
|
||
prompt: "Enter password"
|
||
private: yes
|
||
|
||
- name: "release_version"
|
||
prompt: "Product release version"
|
||
private: no
|
||
|
||
If `Passlib <http://pythonhosted.org/passlib/>`_ is installed, vars_prompt can also crypt the
|
||
entered value so you can use it, for instance, with the user module to define a password::
|
||
|
||
vars_prompt:
|
||
|
||
- name: "my_password2"
|
||
prompt: "Enter password2"
|
||
private: yes
|
||
encrypt: "md5_crypt"
|
||
confirm: yes
|
||
salt_size: 7
|
||
|
||
You can use any crypt scheme supported by 'Passlib':
|
||
|
||
- *des_crypt* - DES Crypt
|
||
- *bsdi_crypt* - BSDi Crypt
|
||
- *bigcrypt* - BigCrypt
|
||
- *crypt16* - Crypt16
|
||
- *md5_crypt* - MD5 Crypt
|
||
- *bcrypt* - BCrypt
|
||
- *sha1_crypt* - SHA-1 Crypt
|
||
- *sun_md5_crypt* - Sun MD5 Crypt
|
||
- *sha256_crypt* - SHA-256 Crypt
|
||
- *sha512_crypt* - SHA-512 Crypt
|
||
- *apr_md5_crypt* - Apache’s MD5-Crypt variant
|
||
- *phpass* - PHPass’ Portable Hash
|
||
- *pbkdf2_digest* - Generic PBKDF2 Hashes
|
||
- *cta_pbkdf2_sha1* - Cryptacular’s PBKDF2 hash
|
||
- *dlitz_pbkdf2_sha1* - Dwayne Litzenberger’s PBKDF2 hash
|
||
- *scram* - SCRAM Hash
|
||
- *bsd_nthash* - FreeBSD’s MCF-compatible nthash encoding
|
||
|
||
However, the only parameters accepted are 'salt' or 'salt_size'. You can use your own salt using
|
||
'salt', or have one generated automatically using 'salt_size'. If nothing is specified, a salt
|
||
of size 8 will be generated.
