Schedule Periodic Builds in Atlas
Atlas 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, Atlas will automatically queue a build that runs 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 aritfact 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 in Atlas 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, Atlas will not queue a new build until the alloted time after the manual build ran. This means that Atlas simply ensures that a build has been executed at the specified schedule.
