Delegate Task Category Mapping

Updated 1 year ago by Michael Cretzman

The Task Category Map feature replaces the Command setting in Delegate Scopes, which is deprecated and will be removed soon.

Harness deployments are broken down into separate tasks performed by Harness Delegates.

Tasks are organized by category. For example, all the connections and images pulled using Docker Hub are part of the Docker Hub Task Category.

By default, Harness performs tasks using any available Delegates. If you want Harness to prioritize a specific Delegate for a task category, you can map the task category to a Selector, and apply that Selector to a Delegate.

The mapped Selector can also be used in certain Harness entities to prioritize Delegates, such as Cloud Providers and the Shell Script Workflow step.

This topic describes how to map task categories to Selectors, and then apply the Selector to one or more Delegates.

Before You Begin

The Delegate is a key component of your Harness setup. Please review the following topics to ensure you have a solid understanding of the Delegate:

Supported Platforms and Technologies

See Supported Platforms and Technologies.

Visual Summary

Here is example of adding a new Selector to a Delegate, and then mapping the Selector to a Task Category:

Here is an example of adding a Selector to a Task Category Mapping, and then applying the Selector to a Delegate:

Step 1: Set Permissions

To map Selectors to Task Categories a user must belong to a User Group with the Account Permission Manage Delegates enabled.

See Managing Users and Groups (RBAC).

Step 2: Map a Selector to a Task Category

  1. To map a Selector to a Task Category, in Setup, click Harness Delegates.
  2. Click Task Category Map.
  3. Click Map Task Category.
  4. In Task Category, select the category you want to map. See Review: Task Categories.
  5. Select or create selectors to map to this Task Category.
    1. You can simply enter the name of a new Selector and click Create.
    2. If you have an existing Selector, one that is perhaps already used by a Delegate or Delegate Profile, you can start entering its name and it will appear. Next, click its name to select it.
      You must select or create at least one Selector.
  6. Click Submit. The Task Category is now mapped to the Selector.

If this Selector is not being used by a Delegate or Profile, you can now add it to one or both.

Review: Applying Selectors to Delegates and Profiles

Once you have mapped a Selector to a Task Category, you can apply the Selector to a Delegate using the following options:

  • Add the Selector to the Delegate's Custom Selectors setting.
  • Add the Selector to a Delegate Profile, and then add the Profile to any Delegates. All the Delegates using that Profile are thereby mapped to the Task Category.

For steps on adding Custom Selectors, see Select Delegates with Selectors.

For steps on adding Profile Selectors, see the Selector option in Run Scripts on Delegates using Profiles.

Which option to use?

If your task requires a Delegate Profile, it is best to map the Task Category to a Selector and apply that Selector to the Profile. All Delegates assigned that Profile will then perform the mapped tasks.

If your task can only be performed by specific Delegates because of their location or credentials, it is best to map it to specific Delegate using a Delegate's Custom Selectors setting.
