Lambda

Example permissions policy

This policy grants access to create, update, delete and invoke Lambda functions. It only allows executing functions whose names begin with the "Deserted-Chateau-Test" prefix.

Note the iam:PassRole permission; when you attach this policy to a user, that user needs permission to assume the Lambda execution role that actually executes your function.
