Add quotes to elemens of the list in jinja2 (ansible)

Question

I have very simple line in the template:

ip={{ip|join(', ')}}

And I have list for ip:

ip:
 - 1.1.1.1
 - 2.2.2.2
 - 3.3.3.3

But application wants IPs with quotes (ip='1.1.1.1', '2.2.2.2').

I can do it like this:

ip:
 - "'1.1.1.1'"
 - "'2.2.2.2'"
 - "'3.3.3.3'"

But it is very ugly. Is any nice way to add quotes on each element of the list in ansible?

Thanks!

Answer 1

This will work :

ip={{ '\"' + ip|join('\", \"') + '\"' }}

A custom filter plugin will also work. In ansible.cfg uncomment filter_plugins and give it a path, where we put this

def wrap(list):
    return [ '"' + x + '"' for x in list]

class FilterModule(object):
    def filters(self):
        return {
            'wrap': wrap
        }

in a file called core.py. Like this. Then you can simply use

ip|wrap|join(', ')

And it should produce comma seperated list with each ip wrapped in quotes.

Actually there is a very simple method to achieve this:

{{ mylist | map('quote') | join(', ') }}

The filter map iterates over every item and let quote process it. Afterwards you can easily join them together.
