» Schedule Periodic Builds in Terraform Enterprise
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 can automatically run a Packer build and create artifacts on a specified schedule. This option is disabled by default and can be enabled by an organization owner on a per-environment basis.
On the specified interval, builds will be automatically queued that run Packer for you, creating any artifacts and sending the appropriate notifications.
If your artifacts are used in any other environments and you have activated the plan on artifact upload feature, this may also queue Terraform plans.
This feature is useful for maintenance of images and automatic updates, or to build nightly style images for staging or development environments.
» Enabling Periodic Builds
To enable periodic builds for a build, visit the build settings page and select the desired interval and click the save button to persist the changes. An initial build may immediately run, depending on the history, and then will automatically build at the specified interval.
If you have run a build separately, either manually or triggered from GitHub or Packer configuration version uploads, Terraform Enterprise will not queue a new build until the allowed time after the manual build ran. This ensures that a build has been executed at the specified schedule.
