Terraform 1 6

Terraform 1.6

This overview applies when the project's target Terraform version is at least 1.6.

Testing

• terraform test is generally available. Tests live in .tftest.hcl files as ordered run blocks that execute plans and optional applies, then evaluate assertions against plan and state values.
• Test runs can pass outputs from earlier runs into later runs. Test cleanup destroys infrastructure in reverse run order.

Import and planning

• An import block's id accepts an expression when it resolves to a string known at plan time.
• HCP Terraform and Terraform Enterprise remote plans can be saved with -out, inspected with terraform show, and applied from the saved plan file.
• Refined unknown values can carry facts such as non-nullness or collection length ranges, allowing more expressions to produce known plan results.

S3 backend migration

• Assume-role settings move into an assume_role block.
• Service endpoint overrides move into an endpoints block.
• shared_credentials_files replaces shared_credentials_file, and use_path_style replaces force_path_style.
• Standard AWS_ENDPOINT_URL_* variables replace the older Terraform-specific endpoint environment variables.

Compatibility

• Terraform 1.6 requires macOS 10.15 or later and Windows 10 or Windows Server 2016 or later.
