Is there a credential helper?

Scalr supports credential helpers if you have a use case where it is needed. To use the helper remotely, it must be installed in the following location within the workspace: terraform.d/plugins/terraform-credentials-scalr.

For self-hosted customers, the helper can be added and configured on the Scalr worker server for global use in the following location: /opt/scalr-server/var/lib/tf-worker/plugins/terraform-credentials-scalr
