Terraform 1.11 brings ephemeral values to managed resources with write-only arguments

  • HashiCorp Terraform 1.11 is now available, featuring write-only arguments for managed resources.
  • Write-only arguments allow the use of ephemeral values in specific resource arguments, enhancing security.
  • Terraform 1.10 introduced ephemeral values for handling sensitive data, and 1.11 extends this to managed resources.
  • With write-only arguments, values can only be written to and not read, adding an extra layer of security.
  • By using write-only arguments, secrets like passwords can be securely passed to resources without being exposed in artifacts.
  • Examples of write-only arguments are master_password_wo in AWS resources and administrator_password_wo in Azure resources.
  • Upgrades to Terraform tests include new features like state_key attribute, mocked values during unit tests, and JUnit XML test reports.
  • Users can download Terraform 1.11, sign up for HCP Terraform, and explore tutorials for upgrading RDS major versions.
  • Partners like Juniper, Palo Alto Networks, and Fortinet are commended for adopting ephemeral values for enhanced security.
  • The community's feedback and contributions played a vital role in shaping Terraform 1.11. Thanks to all contributors.
