How to find a match using regex in ansible playbook where variable appears in the regex_search
argument?
The following playbook doesn't find the match... when run using: ansible-playbook playbook.yml
- hosts: localhost
gather_facts: no
tasks:
- set_fact:
pattern: "{{ 'foobar' | regex_search('foo') }}"
- set_fact:
m: "{{ 'beefoo' | regex_search('bee{{ pattern }}') }}"
- debug:
msg: "hi {{ m }}"
Depends on the ansible
's version you're using. As far as I know, you can use that expression in a version greater than 2.4.0. For lower versions you can use regex_search('^' + pattern | string)
.
So your code will be something like this:
- hosts: localhost
gather_facts: no
tasks:
- set_fact:
pattern: "{{ 'foobar' | regex_search('foo') }}"
- set_fact:
m: "{{ 'beefoo' | regex_search('bee' + pattern | string) }}"
- debug:
msg: 'hi ' + m | string
