     9  # Schedule Periodic Builds in Terraform Enterprise
    10  
    11  Terraform Enterprise can automatically run a Packer build and
    12  create artifacts on a specified schedule. This option is disabled by default and can be enabled by an
    13  organization owner on a per-[environment](/docs/enterprise/glossary#environment) basis.
    14  
    15  On the specified interval, builds will be automatically queued that run Packer
    16  for you, creating any artifacts and sending the appropriate notifications.
    17  
    18  If your artifacts are used in any other environments and you have activated the
    19  plan on artifact upload feature, this may also queue Terraform plans.
    20  
    21  This feature is useful for maintenance of images and automatic updates, or to
    22  build nightly style images for staging or development environments.
    23  
    24  ## Enabling Periodic Builds
    25  
    26  To enable periodic builds for a build, visit the build settings page and select
    27  the desired interval and click the save button to persist the changes. An
    28  initial build may immediately run, depending on the history, and then will
    29  automatically build at the specified interval.
    30  
    31  If you have run a build separately, either manually or triggered from GitHub or
    32  Packer configuration version uploads, Terraform Enterprise will not queue a new
    33  build until the allowed time after the manual build ran. This ensures that a
    34  build has been executed at the specified schedule.
