Argo Agent¶
HTTP Templates use the Argo Agent, which executes the requests independently of the controller. The Agent and the Workflow
Controller communicate through the WorkflowTaskSet CRD, which is created for each running Workflow that requires the use
of the Agent.
In order to use the Argo Agent, you will need to ensure that you have added the appropriate workflow RBAC to add an agent role with to Argo Workflows. An example agent role can be found in the quick-start manifests.
