Create an HTTP step template

The Harness Template Library enables you to standardize and distribute reusable Step Templates across teams that use Harness.

This topic walks you through the steps to create an HTTP Step template.

Objectives​

You'll learn how to: 

  • Create an HTTP Step Template.
  • Define Template parameters.
  • Use the HTTP Step Template in a Pipeline.

Before you begin​

Step 1: Create a Template​

First, we'll create a Project-level Template in the Deployments module. You can do this in any Project.

Navigate to the Deployments module and in Projects select the desired project.

Next select Templates under Project Setup.

Click New Template.

Select Step to create a Step Template.

The Create New Step Template settings appear.

In Name, enter a name for the template. You can enter Quickstart.

In Version Label, enter a name for the version of the template. You can enter V1.

Click Save. The Step Library panel appears.

Step 2: Add Step Parameters​

In Step Library, select HTTP under Utilities.

The Step Parameters settings appear.

In Timeout, enter a timeout value for this step. You can enter 10s.

In URL, enter the URL for the Http call.

In Method, select GET.

Click Save. The new Template appears under the Templates list.

Step 3: Add the HTTP Step Template to a Pipeline​

To add a step template in a Pipeline Execution select the step and click Add Step.

The Step Library panel appears.

In Step Library, select HTTP under Utilities. The HTTP Step settings appear.

Click Use Template. The next page lists all the Project-level templates.

Select the Template that you created.

Click the Activity Log to track all Template events. It shows you details like who created the Template and Template version changes.

Click Version Label.

Select Stable version of the template. This ensures that any changes that you make to this version are propagated  automatically to the Pipelines using this template.

Click Use Template.

In Name, enter Quickstart.

Under Template Inputs, click Timeout and select Runtime input.

Click URL and select Runtime input.

Use Runtime Inputs instead of variable expressions: when you want to template settings in a Stage or step template, use Runtime Inputs instead of variable expressions. When Harness tries to resolve variable expressions to specific Stage-level settings using fully-qualified names, it can cause issues at runtime. Every Pipeline where the Stage or step template is inserted must utilize the exact same names for fully-qualified name references to operate. With Runtime Inputs, you can supply values for a setting at deployment runtime.Click Apply Changes.

Click Save.
