Calling a puppet function inside a ruby task

[Raghu Ram Baisani]

Hi

Suppose if we have a module named temp,

and we have a puppet function named func1

which resides in temp\lib\puppet\functions\temp\func1.rb

and I have another ruby task in the same module,

temp\tasks\task1.rb

How can I call puppet function func1 on task task1?

Any kind help is appreciated

Cheers

Hi Raghuram,

this cannot be (easily) achieved from a Task, as the Task execution environment is not Puppet but basically the target's shell.

You can do this from a Bolt Plan however:

1. In your Bolt module (where your task lives), create a functions folder at the root
2. Place your function in that folder, i.e.f /functions/func1.rb
3. Namespace the function according to your module name, for example mymodule::func1
4. You can now use the module in a Bolt Plan (under /plans) with mymodule::func1(args)

Thanks Kevin

I'm kind of aware of plan option.

Can you please detail the option for task with an example so that I can know how it works.

Hi Raghuram,

The short of it is that you can't make that work in a Task, the Bolt Task environment is simply not designed for this. You have to use a plan.

You can have the Plan call the function and pass the results as parameters to your Task though:

plan mymodule::test {

$func_result = mymodule::func1('arg1', 'arg2')

# assuming mymodule::func1() returns a simple string

run_task('mymodule::mytask', 'target.company.com', 'myparam' => $func_result)

}
