A module that uses a data resource (runs on every plan step) to assume a role using STS and return a temporary access key. This is particularly useful when you need to use external scripts (AWS CLI) to perform actions that can't be done via the Terraform AWS provider; you can use this module to retrieve temporary credentials, then set them in the environment variables for the external script you need to run.
The input variables are the same as those for the aws sts assume-role CLI command, although are provided in snake case.
