I have a requirement where I need to check for a file on the puppet master and copy it to the agent only if it is not empty.
I have the following so far:...

You cannot use an
Exec resource to perform the check, because you need to perform the evaluation during catalog building, and resources are not applied until after the catalog is built. Moreover, the
test command tests for the existence of a the specified path. It does not know about URLs, and even if it did, it would be unlikely to recognize or handle the
puppet: URL scheme. Furthermore, there is no association whatever between resource titles and variable names.
To gather data at catalog building time, you're looking for a puppet function. It is not that hard to add your own custom function to Puppet, but you don't need that for your case -- the built-in
file() function will serve your purpose. It might look something like this:
So for a hobby project of mine, I would like to create an application that translates an HTTP call and request between two services.
The application does that based on a configuration that can be set by the user. The idea is that the application listens to an incoming API call translates the call and then forwards it.
Then the application waits for a response then translates the response and sends it back to the caller.
A translation can be as simple as renaming a field value in a body object or replace a header field to the body.
I think a translation should begin with mapping the correct URL so here is an example of what I was thinking of a configuration should look like:...

I have done something sort-of-similar in a different context (generate code from an input specification), so I will provide an outline of what I did to provide some food for thought. I used Config4* (disclosure: I developed that). If the approach I describe below is of interest to you, then I suggest you read Chapters 2 and 3 of the Config4* Getting Started Guide to get an overview of the Config4* syntax and API. Alternatively, express the concepts below in a different configuration syntax, such as XML.
Config4* is a configuration syntax, and the subset of syntax relevant to this discussion is as follows:
I have written separate playbooks for tomcat deployment on both Ubuntu and Linux as well, instead of mentioning **
when: ansible_distribution == 'Ubuntu'
**in every line in the playbook, i want to run the whole playbook only when this condition meets.
This is my code...

Q: "I want to run the playbook only on the hosts based on the ansible_distribution."
A: It's not possible to include a playbook. This would run the playbooks recursively.
Only import of a playbook is available. Moreover import_playbook is not a task. It's simply a tool to modularize large playbooks with multiple plays.
Ansible conditionals do not apply to
import_playbook the same way as they do not apply to playbooks.
Instead, it is possible to create a group that will be used in the playbook.
