Terraform ServiceNow Service Catalog Integration Administrator Guide
ServiceNow administrators have several options with configuring the Terraform integration.
If you haven't yet installed the integration, see the installation documentation.
Once the integration has been installed, you can add and customize a service catalog and VCS repositories using the service catalog documentation.
You can also configure how frequently ServiceNow will poll HCP Terraform using the documentation below.
Configure Polling Workers
The integration includes 3 ServiceNow Scheduled Flows to poll the HCP Terraform API using ServiceNow Outbound HTTP REST requests. By default, all flows schedules are set to 5 minutes. These can be customized inside the ServiceNow Server Studio:
- Select the Worker Poll Run State Flow.
- Adjust Repeat Intervals
- Click "Done"
- Click "Save"
- Click "Activate"
Worker Poll Apply Run
This worker approves runs for any workspaces that have finished a Terraform plan and are ready to apply their changes. It also adds a comment on the request item for those workspaces notifying that a run has been triggered.
Worker Poll Destroy Workspace
This worker looks for any records in the Terraform ServiceNow table that are
marked for deletion with the value is_destroyable set to true. It then checks
the status of the workspace to ensure it is ready to be deleted. Once the
destroy run has been completed, this work will send the delete request for the
workspace to Terraform.
Worker Poll Run State
The worker synchronizes ServiceNow with the current run state of Terraform workspaces by polling the HCP Terraform API. On state changes, the worker adds a comment to the ServiceNow request item with the updated run state and other metadata.
