HashiCorp Terraform is not currently available on the Photon OS repository. If you would like to install Terraform on a PhotonOS appliance you can use the script below. Note: The versions for Go and Terraform that I have included are current at the time of writing. Thanks to my colleague Ryan Johnson who shared this method with me some time ago for another project.
