# QA has a new process to test Terraform using RCs. We will not publish RCs
# onto the Terraform registry because Hashicorp could potentially block our
# testing by being slow to publish.

# Instead, we will test using a downloaded binary from the RC. This script
# sets up the correct binary using a defined <provider> <version> to test
# updates locally.

# ./setup-provider.sh <provider> <version>

# Example
# ./setup-provider.sh rancher2 v3.0.0-rc1

set -e
