Managing Packer Versions

Terraform Enterprise does not automatically upgrade the version of Packer used to run builds or compiles. This is intentional, as occasionally there can be backwards incompatible changes made to Packer that cause templates to stop building properly, or new versions that produce some other unexpected behavior.

All upgrades must be performed by a user, but Terraform Enterprise will display a notice above any builds run with out of date versions. We encourage the use of the latest version when possible.

Upgrading Packer

1. Go the Settings tab of a build configuration or application
2. Go to the "Packer Version" section and select the version you wish to use
3. Review the changelog for that version and previous versions
4. Click the save button. At this point, future builds will use that version
