Schedule Periodic Plans in Atlas

Schedule Periodic Plans in Atlas

This is an unreleased beta feature. Please contact support if you are interested in helping us test this feature.

Atlas can automatically run a Terraform plan against your infrastructure 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 plan that runs Terraform for you, determining any changes and sending the appropriate notifications.

When used with automatic applies, this feature can help converge changes to infrastructure without human input.

Atlas will not queue new runs while another plan or apply is in progress, or if the environment has been manually locked. See Environment Locking for more information.

Enabling Periodic Plans

To enable periodic plans for an environment, visit the environment settings page in Atlas and select the desired interval and click the save button to persist the changes. An initial plan may immediately run, depending on the state of your environment, and then will automatically plan at the specified interval.

If you have manually run a plan separately, Atlas will not queue a new plan until the alloted time after the manual plan ran. This means that Atlas simply ensures that a plan has been executed at the specified schedule.
