Installing or upgrading the plug-in involves downloading the latest installer file and using the vCenter Orchestrator Configuration UI to upload the plug-in file and install the plug-in.

About this task

This topic provides specific guidance for installing the Horizon vCenter Orchestrator plug-in. The procedure for installing vCenter Orchestrator plug-ins is similar for all plug-ins, and the documentation for general plug-in installation, update, and troubleshooting is provided elsewhere. See the vCenter Orchestrator Documentation page at https://www.vmware.com/support/pubs/orchestrator_pubs.html.

Prerequisites

  • Verify that you have the URL for downloading the Horizon vCenter Orchestrator plug-in installation file (.vmoapp file).

  • Verify that you have vCenter Orchestrator (either the virtual appliance or the Windows service) set up and configured to work with vCenter Single Sign-On. See "Register Orchestrator as a vCenter Single Sign On Solution in Advanced Mode" in Installing and Configuring VMware vCenter Orchestrator.

  • Verify that you have credentials for an account with permission to install vCenter Orchestrator plug-ins and to authenticate through vCenter Single Sign-On.

  • Verify that you have installed VMware vCenter Orchestrator Client and that you can log in with Administrator credentials.

Procedure

  1. Download the plug-in file to a location accessible from the vCenter Orchestrator appliance or service.

    The installer filename is o11nplugin-horizon-1.1.0-xxxxxxx.vmoapp, where xxxxxx is the build number.

  2. Open a browser and launch the vCenter Orchestrator Configuration interface.

    An example of the URL format is https://server.mycompany.com:8283.

  3. Click the Plug-ins item in the left pane and scroll down to the Install new plug-in section.
  4. In the Plug-in file text box, browse to the plug-in installer file and click Upload and install.

    The file must be in .vmoapp format.

  5. In the Install a Plugin pane, when prompted, accept the license agreement.
    Important:

    If you are upgrading, a message appears after the plug-in is installed: Horizon (1.1.0 build xxxxxxx) Plug-in with same name was already installed (1.0.0 build xxxxxxx): overwriting existing plug-in.

  6. Go to the Enabled plug-ins installation status section and confirm that Horizon 1.1.0.xxxxxxx is listed, where xxxxxx is the build number.

    You see a status message for the installation or upgrade.

    Type of Installation

    Message

  7. Restart the vCenter Orchestrator Server service.
  8. Restart the vCenter Orchestrator Configuration service.
  9. Launch the vCenter Orchestrator Configuration interface again, click the Plug-ins item, and verify that the status changed to Installation OK.

What to do next

Launch the vCenter Orchestrator Client application, log in, and use the Workflow tab to navigate through the library to the Horizon folder. You can now browse through the workflows provided by the Horizon vCenter Orchestrator plug-in.
