The OpentTF foundation that has been founded in a response to the Terraform license change has announced a fork of HashiCorp's IaC (Infrastructure as Code) tool. The first release of the OpenTF tool will be 1.6.0-alpha, forked from the most recent commit of Terraform that was still MPL-licensed. According do the announcement OpenTF will be a drop-in replacement for Terraform.
OpenTF intends to become part of a more powerful entity so it has completed all documents required for OpenTF to become part of the Linux Foundation with the end goal of having OpenTF as part of Cloud Native Computing Foundation. While the code proper is not available yet the roadmap to getting there is published in an OpenTF Github repo.
