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.
|
1 2 3 4 5 6 7 8 |
[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.
|
1 2 3 4 |
[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.
|
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 }}' |
Step-4
Run ansible playbook.
|
1 2 3 4 |
bash-3.2$ pwd /Users/Shared/ansible bash-3.2$ ansible-playbook -vvv crunchify.yml |
Checkout console output:
|
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 |
