C.4. Example User Interface Plug-in Deployment

Follow these instructions to create a user interface plug-in that runs a Hello World! program when you sign in to the Red Hat Enterprise Virtualization Manager administration portal.

Procedure C.2. Deploying a Hello World! Plug-in

  1. Create a plug-in descriptor by creating the following file in the Manager at /usr/share/ovirt-engine/ui-plugins/helloWorld.json:
    {
        "name": "HelloWorld",
        "url": "/ovirt-engine/webadmin/plugin/HelloWorld/start.html",
        "resourcePath": "hello-files"
    }
    
  2. Create the plug-in host page by creating the following file in the Manager at /usr/share/ovirt-engine/ui-plugins/hello-files/start.html:
    <!DOCTYPE html><html><head>
    <script>
        var api = parent.pluginApi('HelloWorld');
        api.register({
    	UiInit: function() { window.alert('Hello world'); }
        });
        api.ready();
    </script>
    </head><body></body></html>
    
If you have successfully implemented the Hello World! plug-in, you will see this screen when you sign in to the administration portal:
