User input variables in Python Script

[mattronix]

Hello Team,

How do i get User input variables in a python or bash script, did a scan through the docs and code in here and was not sure if they actually use that functionality.

you need to define them as inputs in offering. they are passed as capitalized environment variables to the scripts

Code is here: https://github.com/waldur/waldur-mastermind/blob/6ab1e71c2a0f2ab5e6bf974cab742578e1963086/src/waldur_mastermind/marketplace_script/utils.py#L238C15-L238C15

Amazing Thank you :)

Do i use os.environ to access the keys?

As so far i get none if i use the internal name in Upper case

[mattronix]

Dont quite understand how to access this variable ("environment"):

environment = { key.upper(): input_parameters[key] for key in input_parameters.keys() }

[mattronix]

ah its passed through as

caught me off guard

When i try to load and display the attributes still get issues :(

import os
import json
import re

def run():
    print("Hello World!")

if __name__ == "__main__":
    run()
    attributes = json.loads(os.environ.get("ATTRIBUTES"))
    print(attributes)

Error message
[ErrorDetail(string='Unexpected structure of output', code=["{'name':", "'test',", "'secret':", "'tEAT'}"])]

Took that reference from the custom examples in here, i can see its probably the " vs ' but how does this work for you if its not working in my case, probably better that i use ast literal instead.

[mattronix]

Got it working in the end:

import os
import json
import re
import ast

def run():
    print("Hello World!")
    attributes = json.loads(os.environ.get("ATTRIBUTES"))
    print(attributes)
    print(type(attributes))
    print(attributes["secret"])

if __name__ == "__main__":
    run()
