» Managing Packer Versions
Deprecation warning: The Packer, Artifact Registry and Terraform Enterprise (Legacy) features of Atlas will no longer be actively developed or maintained and will be fully decommissioned on Thursday, May 31, 2018. Please see our Upgrading From Terraform Enterprise (Legacy) guide to migrate to the new Terraform Enterprise and our guide on building immutable infrastructure with Packer on CI/CD for ideas on implementing the Packer and Artifact features yourself.
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All upgrades must be performed by a user, but Terraform Enterprise will display a notice above any builds run with out of date versions.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.
