Overview

...

The HyperCloud™ Platform (HCP) lets you create and execute script scripts on the VMs once provisioned successfully. Virtual Machines (VMs.) These scripts are call plugins & HyperCloud™ Platform support the following interpreterscalled Plugins on the HCP portal. The HCP portal supports these interpreters:

• Bash

• Python

• Perl

• Ruby

• PowerShell

• Puppet

To run plugins, HyperCloud™ agent must be installed a Plugin on a VM, you’ll need to install the HCP agent. You can install the HCP agent on the VM provisioned via using a Blueprint or Free-Form Wizard. HyperCloud™ plugin can be included in a blueprint which get executed automatically once the VM is successfully provisioned. With the use of blueprints and plugins, Virtual Machine templates can be preserved in form of YAML and reduce the need of creating custom images.
Note: Plugins are only available for VMs and are not applicable to other types of blueprints

Plugins are Docker containers that perform pre-defined tasks. These tasks are executed as steps in your HCP pipeline. You can use Plugins to deploy code, publish artifacts, send notifications, etcetera.
Follow these steps to create a Plugin:

1. Log in to your HCP portal account.

2. Click Service Orchestration and navigate to Appstore > Plugins > Click New > Select the Plugin Type from the drop-down list.

            Example:
            Key: IP_ADDRESS Value: 8.8.8.8

   3. To entitle users to your Plugin, select: 

      • Only Me: if you do not want anyone to access your Plugin.

      • Everyone: if you want to share your Plugin with everyone.

      • Groups & Users: if you want to share the Plugin with specific users or groups.

        1. Enter the first three alphabets of the username in the Users drop-down and select the username.

        2. Type the first three alphabets of the Group Name in the Groups drop-down and select the group name.

4. Click Save Changes.

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

Run your plugin on-demand

...

Follow these steps to run your plugins on-demand on an existing VM without having to connect to the VM: ^[1]

1. Log in to your HCP portal account.

2. Click on Service Orchestration and navigate to Services > VM > Click open your VM > Click Plugins.

      1. Valid Exit Codes: when you state a valid exit code, the HCP portal will ignore these codes. If you do not provide an exit code, the HCP portal will substitute it with the default value, which is 0.

      2. Order: this lets you define the sequence for the Order of executing the Plugin. ^[3]

4. Click Run Plugin.

5. Click Timeline Tab and wait for a few minutes to see the status of your run.

Add Plugin to a Blueprint using parameters

...

You can use parameters in blueprints to pass or override the default plugin values. You can add a plugin to different blueprints and customize your deployments using parameters. Follow these steps to add parameters to your Plugin for an existing blueprint:
