Use environment variables in a Custom action

Objective

In a Custom action, you might want to use environment variables. You can set your own in the preferences or set them in the JSON Advanced Mode of the action, in the params JSON object, and re-use them in your custom action.

import sys
from logging import getLogger
from forepaas.core.settings import PARAMS

logger = logging.getLogger(__name__)

def my_custom(event):
	try:
		# Show the parameter value
		logger.info("Environment variable value is: ".format(PARAMS["env variable key"]))

	except Exception as err: 
		raise Exception("err:{} L:{}".format(err,sys.exc_info()[2].tb_lineno))
