Escaping { character in a task that has an ansible variable

Archives Ansible Project

Hello all,

I have a task that need to run the command below:

ipa dnsrecord-add idm.example.com cluster --a-rec={192.0.2.40,192.0.2.41}

The problem is that the IPA and ansible both use the "{" character. I
have attempted to escape one of the "{" with a back slash, and ansible
is fine with that, but then the resulting command isn't valid as far
as IPA server is concerned.

How would you guys go about resolving this? This is what I am seeing.

I don't now why you have those square brackets in there since you command should not have them according to your command on top.
To get the curly bracket in just use string concatenation.

--a-rec={{ '{' ~ ip | join(',') ~ '}' }}
