Transform dictionary into lists for module consumption

I am trying to simplify some variable files for our developers and I am wondering if I can do this transform with existing filter/lookup plugins Ansible.

I’ll have this dictionary (and the fields are not static, there could be more settings):

OptionSettings:
aws:elasticbeanstalk:command:
BatchSize: ‘30’
BatchSizeType: Percentage
aws:elasticbeanstalk:sns:topics:
Notification Endpoint: me@example.com

And I want to transform the elements under OptionSettings to match what the module/API is expecting:

OptionSettingsTransform:

  • Namespace: aws:elasticbeanstalk:command
    OptionName: Batch Size
    Value: “30”
  • Namepsace: aws:elasticbeanstalk:command
    OptionName: BatchSizeType
    Value: Percentage
  • Namespace: aws:elasticbeanstalk:sns:topics
    OptionName: Notification Endpoint
    Value: me@example.com

So it involves iterating over each subelement of OptionSettings and then each subelement of each namespace while retaining the namespace it is working within. I have tried looking at with_items, together, subelements, but I can’t seem to wrap my head around it. Any ideas? Is this too much and would I need to implement a custom lookup plugin in python to do this?

Any help/suggestions would be appreciated :slight_smile:

Use the jinja map attribute function to extract the items into a list.

I’ve put together an example here
http://docs.ansible.com/ansible/ec2_vpc_subnet_facts_module.html

There is some more documentation here with links here

Sorry I don’t have the time to go through a full example with your use case, hope this helps.
