HashiCorp is introducing a new feature called variable sets in its Terraform Cloud platform, which allows users to simplify the management of reusable variables across an entire organization. This feature is now available in public beta and enables organizations to reuse both Terraform-defined and environment variables across workspaces or the entire organization. Variable sets can be used for credential management, cost optimization, tagging, and other use cases, and have their own precedence rules. The new API service allows users to manage variable sets programmatically. Variable sets are available to all tiers of Terraform Cloud users and can be accessed through the documentation and a new HashiCorp Learn guide.
