vSphere SDK for JavaScript Fling released

02.03.2016 by William Lam // 2 Comments

The VMware Fling team has just released another cool new Fling, the vSphere SDK for JavaScript. This Fling is especially interesting as it provides the underlying SDK framework used by the popular ESXi Embedded Host Client Fling which was released back in August of last year. I came to learn about this project during last years internal R&D Innovation Offsite (RADIO) conference which is held annually and can be thought of as the VMworld conference for VMware employees.

One of the biggest highlight of the conference for me personally is checking out the expo floor where you get to see what other VMware Engineering teams have been working on whether it is the next big feature, product or new ideas that they might be thinking about. It was during my walk through that I met Rostislav Hristov, one of the Engineers who worked on the vSphere SDK for JavaScript. I was really impressed at what Rostislav built and luckily he was already in touch with the Embedded Host Client Engineers to see how they could leverage his JavaScript SDK as the initial prototype had made calls directly using the vSphere MOB which was not very friendly to develop against.

There has been a number of improvements to the vSphere SDK for JavaScript since I last saw it and although the name contains "vSphere", it definitely supports more than just the vSphere API endpoint. In fact, with this single SDK you can interact with vCenter Server Single Sign-On (SSO) API, vCloud Suite API which covers capabilities like Tagging and Content Library as well as the Site Recovery Manager (SRM) APIs! For customers and partners that are looking to develop their own web portals or interfaces that can integrate with these APIs, this will be a handy tool to have.

To get started, the vSphere SDK for JavaScript contains a README file that contains additional instructions on setting up the SDK as well as a couple of samples that demonstrates each of the supported API endpoints:

  • vimService.js - Sample using the vSphere API
  • stsService.js - Sample using the SSO API
  • cisServices.js - Sample using the vCloud Suite API
  • srmService.js - Sample using the SRM API

Here is the command to run the vimService.js sample which will also require you to set the environmental variable NODE_TLS_REJECT_UNAUTHORIZED=0 if you are using the default VMware self-signed SSL Certificate.

NODE_TLS_REJECT_UNAUTHORIZED=0 babel-node samples/vimService.js

Once the sample has started up, you will be prompted with a URL to open in your browser. In the vimService.js example, you will be able to login to either a vCenter Server or ESXi host as seen in the screenshot below.

vsphere-sdk-for-javascript-1
Once logged in, you should see a simple listing of the different inventory objects in your vSphere enviornment.

vsphere-sdk-for-javascript-2
In the stsService.js sample, once logged in by specifying the address to your PSC/SSO instance, you should see that a SAML token was issued.

vsphere-sdk-for-javascript-3
The cisService.js sample exercises several operations using a mixture of both the vSphere API as well as the new vCloud Suite API. It does require connecting to a vCenter Server 6.0 environment as it will be performing operations using the new vSphere Content Library feature as well as some VM operations. Do not worry, once the operations have been completed, the script will automatically clean itself up. This is a great sample if you want to see how you could make use of the different APIs all through this single SDK.

vsphere-sdk-for-javascript-4-new
I did not have an SRM environment up and running to test the srmService.js sample, but you can see from the code that it will list all of the recovery plans and their current state. For more details on how the individual APIs work, you can refer to the documentation included in the vSphere SDK for JavaScript or the official API documentation for the individual products. If you have any feedback or comments about this Fling, please leave a comment on the Fling site here as I am sure the Engineers would love to hear what you think!

How To Run The SilverLining Fling Without Installing It In vCloud Director

02.26.2013 by William Lam // 5 Comments

A few weeks back the VMware Lab's team released a cool new fling called SilverLining which allows users to build a simplified user-interface for vCloud Director. This interface can be run from any modern web-browser that supports HTML5, CSS3 and Javascript. To access the SilverLining interface, you must first install it on a vCloud Director 5.1 Cell.

From a development or proof of concept perspective, it would be really nice to be able to run SilverLining locally from your desktop and point it to a valid vCloud Director 5.1 instance for testing. Well, this is exactly what Andrea Siviero, a Consulting Architect for VMware discovered while playing around with the SilverLining Fling.

UPDATE: 2/28 - For Safari, you can use open /Applications/Safari.app/ --args -disable-web-security

Disclaimer: The solution described here is specifically for Chrome running on Mac OS X or Windows. I have not looked into equivalent settings for other browsers.

Here are the steps required to make this work:

Step 1 - Download SilverLining and extract the contents to your local desktop

Step 2 - Under Silverlining->js directory, there is a file called main.js that needs to be modified. Add the following right under "$(document).ready(function() {" which should point to the base URL of your vCloud Director instance:

localStorage.server = "https://vcd.primp-industries.com";

Step 3 - Launch Chrome with the additional argument via the command-line and load the index.html in the SilverLining directory:

open /Applications/Google\ Chrome.app/ --args -disable-web-security

Note: For Windows version of Chrome just pass in the following either via command-line or shortcut to Chrome.exe -disable-web-security

If everything was successful, you should be able to login to the vCloud Organization of your choice and see all the vApps and Catalogs you have access to!

If you receive the "You are attempting to connect to a system no longer supported" shown in the screenshot below:

You may be pointing to a vCloud Director instance that is using a self-signed certificate and you will need to trust the site before proceeding. To do so, open up a new tab and enter the following URL (substituting your vCloud Director URL):

https://vcd.primip-industries.com/api/versions

Click on the "Proceed Anyway" and then reload the index.html page and you should now be able to login to vCloud Director.

I would like to thank Andrea for sharing this awesome tip! Now you can easily develop and test your own custom interface using the Javascript SDK provided by SilverLining all on your desktop. Best of all, you can now point this to any remote vCloud Director 5.1 instance whether that be private or public!
