Overview

Note
Among various Blueprint types, only VMs support Plugins.

The HyperCloud™ Platform (HCP) lets you create and execute scripts on Virtual Machines (VMs.) These scripts are called Plugins on the HCP portal. The HCP portal supports these interpreters:

...

To run a Plugin on a VM, you’ll need to install the HCP agent. You can install the HCP agent on the VM using a Blueprint or the Free-from wizard.

Plugins are Docker containers that perform pre-defined tasks and . These tasks are configured executed as steps in your HCP pipeline. You can use Plugins can be used to deploy code, publish artifacts, send notificationnotifications, and moreetcetera.

  1. Once you create your Plugin, the HCP portal will create a unique REFERENCE ID for the same.
    Example: Q5G9A

Note

  • [1] The HCP portal will replace all

occurrence

  • occurrences of:

    • $IP_ADDRESS in the

plugin

    • Plugin with the value 8.8.8.8

. However, HyperCloud

  • The HCP portal will ignore all occurrences of:

    • ${IP_ADDRESS}

if used

    • in the

plugins.

Now you have created your new plugin with a unique REFERENCE ID for e.g. Q5G9A

In the same way plugins can be created for running Perl, python, ruby scripts as well as puppet automation.

Run plugins on demand

Users can run plugins on-demand any of their own existing Virtual Machines without the need of connecting to the VM. Use the following steps to run an existing plugin on an existing VM.
Note: Running plugins on an existing VM requires the HyperCloud™ Agent to be installed on the Virtual Machine. The Agent Status must be Connected.

  • Login to the HyperCloud™ Platform with your credentials  Click on Services Orchestration Tab  Services

  • Click on VMs  Locate and click on the target VM.  Click on Plugins Tab

    • In the Add Plugins Drop-Down scroll or search the plugin name  Select the plugin

Note: If the plugin has been created with Arguments, then text fields will appear under the selected plugin.

...

  • To Add more plugins, click on the Add Plugins and scroll or Type and search the name of another plugin

    • For each plugin, click on +Advance Configuration button and provide the following information

      • Valid Exit Codes: These Exit codes will be ignored. If none provided, then the default value is 0.

        • Order: Sequence number to define the order of execution of the plugin.

Note: If no order number is mentioned, all plugins will run at the same time

      2. Enter the Host in the Key text-box. The Key is visible to your HCP user.

      3. Enterthe Value for your Key. If you do not enter a value for your Key, the HCP portal will default the value to 8.8.8.8.

      4. Select the Mandatory check-box to make it compulsory for your HCP users to provide a Key-Value before creating a VM. [2]
