# HASHISTACK INSTALLER - Automated Installation of the HashiCorp Stack
#
#  Automatically Download, Extract and Install Latest or Specific
#  Version of Terraform, Packer, Consul, Vault, Nomad, Boundary, Waypoint
#
# Largely inspired from https://github.com/robertpeteuil/packer-installer
# and https://github.com/robertpeteuil/terraform-installer
#
# If/when https://iac.sh evovles to support the installation of HashiCorp products other than Terraform and Packer,
# this project will be a good candidate for archives :-)
