How do you handle Ansible prompt?
If you want your playbook to prompt the user for certain input, add a ‘vars_prompt’ section….Ansible supports at most four crypt schemes, depending on your platform at most the following crypt schemes are supported:
- bcrypt – BCrypt.
- md5_crypt – MD5 Crypt.
- sha256_crypt – SHA-256 Crypt.
- sha512_crypt – SHA-512 Crypt.
How do I debug Ansible-playbook?
You can enable the task debugger globally with a setting in ansible. cfg or with an environment variable. The only options are True or False . If you set the configuration option or environment variable to True , Ansible runs the debugger on failed tasks by default.

How do you filter out tasks in ansible?
TL;DR
- use “select” filter to filter a list and “match” to combine it with reg exps, like: “{{ ansible_interfaces | select(‘match’, ‘^(eth|wlan)[0-9]+’) | list }}”
- use “map” to map list elements, like: “{{ ansible_interfaces | map(‘upper’) | list }}”
- use just “+” operator to combine two lists into one, like:
What is SSH password ansible?
By default, Ansible assumes you are using SSH keys to connect to remote machines. SSH keys are encouraged, but you can use password authentication if needed with the –ask-pass option. If you need to provide a password for privilege escalation (sudo, pbrun, and so on), use –ask-become-pass .
What is the difference between shell and command in ansible?
The shell module in Ansible is used to execute all Shell commands against the target Unix-based hosts. The shell module executes commands in nodes or Shell scripts. In the command module, the given command executes on all selected nodes. The executed command will not be processed through the shell.
How to skip a task in Ansible playbook?
When we call ansible-playbook with the –tags parameter, we only execute tasks that have one of the specified tasks. But when we don’t specify any tag, all tasks are run. So we occasionally need a feature that is the opposite of a tag: skipping a set of tasks unless we specify that we want to execute it.
Which is an example of a prompt in Ansible?
In addition to security, prompts support flexibility. For example, if you use one playbook across multiple software releases, you could prompt for the particular release version. Here is a most basic example:
Here is a most basic example: The user input is hidden by default but it can be made visible by setting private: no. Prompts for individual vars_prompt variables will be skipped for any variable that is already defined through the command line –extra-vars option, or when running from a non-interactive session (such as cron or Ansible Tower).
What are the parameters to generate a salt in Ansible?
If you have Passlib installed, you can use any crypt scheme the library supports: The only parameters accepted are ‘salt’ or ‘salt_size’. You can use your own salt by defining ‘salt’, or have one generated automatically using ‘salt_size’. By default Ansible generates a salt of size 8. New in version 2.7.
