Creating an RDS from another RDS's latest automated snapshot

[latt...@securityscorecard.io]

I'm working on porting a shell script over to ansible, and I'm trying to capture the ARN of the latest automated snapshot without using the aws-cli or creating a standalone module. The shell command that would produce the value I'm looking for is

aws rds describe-db-snapshots \

    --query 'DBSnapshots[?DBInstanceIdentifier==`DB-INSTANCE-NAME`&&SnapshotType==`automated`].{Arn: DBSnapshotArn}' \

    --output text | tail -n1

where DB-INSTANCE-NAME is replaced with the actual db instance name.

Coming from Puppet, I would create a parser function inside my roles or profile module written in Ruby. Is there a way to have dynamic variables kept close/in the playbooks, written in python?

Thanks

You can write a Filter Plugin and use that. Here are some that I have written and you can use that as an example. https://github.com/linuxdynasty/ld-ansible-filter-plugins

In this example playbook, you can see how I use them. https://github.com/linuxdynasty/ansible-examples/tree/master/playbooks

You can also read my blog post about it http://linuxdynasty.org/ansible-filters-and-how-they-can-make-aws-your-playbooks-dynamic/.

You can see how much I love Filters :)
