Lesson 5: Create an application process

Application processes direct underlying component processes and orchestrate multi-component deployments.
An application process, like a component process, consists of steps that are configured with the process editor. In this lesson, you create an application process that installs the helloWorld component by calling the component process that you created earlier.

To create an application process:

  1. Click the Applications tab and then click the helloWorld application.
  2. Click Processes and then click Create New Process.
  3. In the Create an Application Process window, name the new application process something like hello App Process.
  4. Accept the default values for the other fields and click Save.
  5. To open the new process in the process editor, click the new process.
  6. Add a step that deploys the helloWorld component:
    1. From the list of steps, add an Install Component step to the design area.
    2. In the Edit Properties window, name the step something like Deploy helloWorld.
    3. In the Component list, select the helloWorld component. All components that are associated with an application are available.
    4. In the Component Process list, select the helloProcess component process. If multiple processes were defined for the helloWorld component, they are listed.
    5. In the Limit to Tag list, select the blueCycle tag that you defined earlier. After you select blueCycle, the application deploys only components with this tag.
    6. Accept the default values for the other fields and click Save.
  7. Connect the Start step to the Deploy helloWorld step.
  8. Connect the Deploy helloWorld step to the Finish step.
  9. Save the process by clicking the Save icon under Tools.
The complete application process looks like the following figure:

Note: You might be wondering why you need an application-level process when the component process that it calls does the actual deployment. The answer is that for a simple, single-component deployment like this one, an application-level process might not be required. After a component is assigned to an application, you can run the component process without first defining an application-level process. You might also skip an application-level process when you are testing or patching a component. But for complex deployments, and especially for deployments that have more than one component, you must create one or more application-level processes.

Lesson checkpoint

In this lesson, you created an application process that deploys the helloWorld component.
The Processes tab lists the application process.
