Getting Started

This section is helpful for deployments as it provides you with pertinent information on prerequisites and properties.

Helpful Background Information

Workflows often include logic that varies from business to business. As a result, we often find that our Workflow Projects are more useful as modular components that can be incorporated into a larger process. In addition, they often can add value as a learning tool on how we integrate with other systems and how we do things within the Itential Automation Platform.

While these can be utilized, you may find more value in using them as a starting point to build around.

Prerequisites

Itential Workflow Projects are built and tested on particular versions of IAP. In addition, Workflow Projects are often dependent on external systems and as such, these Workflow Projects will have dependencies on these other systems. This version of Cisco - NSO has been tested with:

• IAP 2023.1

External Dependencies

Adapters

How to Install

To install the Workflow Project:

• Verify you are running a supported version of the Itential Automation Platform (IAP) as listed above in the Supported IAP Versions section in order to install the Example Project.
• Import the Example Project in Admin Essentials.

Testing

Cypress is generally used to test all Itential Example Projects. While Cypress is an opensource tool, at Itential we have internal libraries that have been built around Cypress to allow us to test with a deployed IAP.

When certifying our Example Projects for a release of IAP we run these tests against the particular version of IAP and create a release branch in GitLab. If you do not see the Example Project available in your version of IAP please contact Itential.

While Itential tests this Example Project and its capabilities, it is often the case the customer environments offer their own unique circumstances. Therefore, it is our recommendation that you deploy this Example Project into a development/testing environment in which you can test the Example Project.
