Ansible: How to Accept User Input using vars_prompt and Command line?

It’s been few months I started playing with Ansible. In this tutorial, we will go over how to use vars_prompt ansible section if you may wish to prompt the user for certain input while running ansible playbook.

Let’s get started:

Step-1

Create hosts file and put it under folder called /Users/Shared/ansible.

[local]
localhost ansible_connection=local ansible_python_interpreter=python
[defaults]
host_key_checking=false
[crunchify]
localhost

Step-2

Put your default ansible.cfg file under the same folder.

[defaults]
ansible_ssh_user=crunchify
inventory=hosts
host_key_checking=false

Step-3

Create file crunchify.yml file in which we will use vars_prompt section to get user input.

---
- 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 }}'

Step-4

Run ansible playbook.

bash-3.2$ pwd
/Users/Shared/ansible

bash-3.2$ ansible-playbook -vvv crunchify.yml

Checkout console output:

bash-3.2$ ansible-playbook -vvv crunchify.yml

How to skip user prompt and accept arguments via command line:

bash-3.2$ ansible-playbook -vvv crunchify.yml -e "website='Crunchify.com' country='United States'"
