10/12/2021, 8:20 PMI'm using Python with the Automation API
I haven't been able to reference modules that are referring to stack metadata because these are initialized outside of the stack initialization
Is there a way to package code with an inline program so that it's used consistently across all stacks?
For example:
config = pulumi.Config()
environment = config.require('environment')
project_name = pulumi.get_project()
AutoTag(environment)I need these lines in every single stack I'm creating

10/12/2021, 8:24 PMI think your normal language constructs would work here. Put that code in a function, call it in the normal way from each project...

10/12/2021, 8:26 PMRight, but the lines after this would be different 🤔

little-cartoon-10569
10/12/2021, 8:27 PMSo only those lines would be in the function...?

10/12/2021, 8:27 PMEach stack would provision it's own resources
The config and tagging would be used everywhere but the resources would be different depending on the stack
If I could chain functions that my work but classes haven't worked for me

10/12/2021, 8:31 PMAre you used either aws:defaultTags or StackTransformation? Both of those can be set up before you create the resources, and then be forgotten about. Should work with this style of code.

So it should always apply.

10/12/2021, 9:28 PM@billowy-army-68599 do you know if it's possible to load

10/12/2021, 9:48 PMdo you know if it’s possible to loadÂI’m not sure what exactly a StackTransformation is - do you have a doc reference? But in general, no. Concepts available from within a pulumi program are not available outside of the program itself. intoÂStackTransformation or anytime beforeÂLocalWorkspaceOptions?stack.up
I’m kinda struggling to wrap my head around what the exact issue is… what are you hoping to achieve?

10/12/2021, 10:23 PMThanks for the link @little-cartoon-10569. Today I learned!
Okay but yeah this is still something you would call from within your
InlineProgramGoing back to tenwit’s original suggestion though… why can’t these lines be a function that is called from within each stack?
def tag_env():
config = pulumi.Config()
environment = config.require('environment')
project_name = pulumi.get_project()
AutoTag(environment)
def my_inline_pulumi_program():
tag_env()
...
def my_other_inline_program():
tag_env()
...l

10/12/2021, 10:29 PMYea, it's not even each stack, it's just each program.. it looks good to me...

10/12/2021, 11:05 PMIs it possible to run multiple inline programs in the same stack?
l
little-cartoon-10569
10/12/2021, 11:07 PMPrograms contain stacks, not vice versa...
r
red-match-15116
10/12/2021, 11:08 PMstacks are usually used to denote environments like staging, dev, prod of the same program.
that doesn’t necessarily have to be the case. for instance, in the little webapp i built, i use stacks to just pump out different resources from the same program: https://github.com/komalali/self-service-platyform/blob/main/app/sites.py#L77-L92

10/12/2021, 11:16 PMWhen you initialize a stack you pass the inline program. That's what I'm referring to

10/12/2021, 11:20 PMIf you pass in a different function to the stack it will override your program and deploy the new program. So no, you cannot run multiple inline programs in a stack.
but your inline program function can call other functions
