Assert in ansible playbook

[Shivani Arora]

Hi All,

I'm creating a playbook which validates user input.

Input string would be something like :  "cluster-test-1"

I want to assert that input has only lowercase, digits or hypen. (No other special character is allowed)

Please suggest how I can achieve this, so that the playbook exits if input validation is failed.

Thanks,

Shivani

How is the user input being supplied to the playbook?

I would do something like this -

 

---

- name: Prompt and validation demo

hosts: localhost

gather_facts: false

vars_prompt:

- name: release_version

prompt: "What is the release version (Allowed values a-z, 0-9, hyphen)?"

private: no

pre_tasks:

- name: Make sure version is ok

fail:

msg: >-

Release version is not formatted correctly.

when: not release_version is regex('^[a-z0-9\-]+$')

run_once: true
