Create the program that manages the extension

An extension communicates with
vCenter Server
across a network, so you can use any programming language to create the program that manages an extension.
The product that you are exposing as an extension to
vCenter Server
determines the way you create the program that will manage your extension. The managing program must implement
Extension
to provide the information that
vCenter Server
requires to register the extension.
For example, you can create a solution that defines its server side in a
MyManager
class.
The
MyManager.java
can performs the following tasks for your solution.
  • Sets up your solution by obtaining the values for the extension key,
    vCenter Server
    connection, IP addresses, and port configuration from the
    mysolution.properties
    file.
  • Secures the connection to
    vCenter Server
    by using TLS.
  • Defines methods to construct the URLs through which to access the server side of the extension.
  • Implements the
    Extension
    object to register your solution as an extension with
    vCenter Server
    .
  • Integrates your solution as a solution with
    ExtensionManager
    .
  • Connects the solution to the ESX Agent Manager.
  • Instantiates the class that defines the ESX agents that the solution deploys.
  • Starts the solution in
    vCenter Server
    .
  • Defines a task to unregister the solution from
    vCenter Server
    .
  1. Create a program to manage your extension using the programming language of your choice.
    For example, you can create a
    MyManager
    class to manage the extension.
    MyManager
    can implement the Spring Framework API.
    public class MyManager implements InitializingBean { }
  2. Create an instance of the
    Extension
    data object with which to register the extension with
    vCenter Server
    .
    The
    MyManager
    class can define an internal method that instantiates an
    Extension
    .
    public class MyManager implements InitializingBean { [...] private Extension createExtensionObject() { Extension extension = new Extension(); [...] } }
Connect the extension to
vCenter Server
.
