vCloud Director 9 HTML5 Portal Customization

One of the great features in vCloud Director 9 which has been further enhanced in the latest v9.5 release is the new HTML5 portal:

Even better, VMware has released a toolkit to allow Service Providers to fully customise the look and feel of the portal using CSS themes in their Clarity framework..

The toolkit itself is part of the VMware vcd-ext-sdk repository on github, available in the /ui/theme-generator folder.

The repository has good instructions on how to modify and build a custom theme, but actually uploading and configuring the theme in vCloud Director is only accessible via the vCD API and involves a reasonable amount of manual work.

To help speed up development and allow changes to be easily tested, in my usual mode I’ve written a small PowerShell module that allows quicker/easier theme configuration. The module is available on github at https://github.com/jondwaite/vcd-h5-themes. Hopefully this will help those of you who need to develop and test updated themes for your vCloud Director portals.

I’ve included documentation in the repository on each cmdlet, its function and arguments here.

To use the module you’ll need to be connected to a vCloud instance as a user with global ‘Administrator’ access in the ‘System’ organization since changes will affect all portal users. You’ll need to be connected to the vCD environment with PowerCLI (Connect-CIServer…) prior to using the cmdlets.

You can then download the vcd-ht-themes.psm1 file and add it to your session (‘Import-Module vcd-h5-themes.psm1’) to access the cmdlets.

As always, comments and feedback welcome – is there anything else you’d like to see added to this module?

VM Guest Customization in vCloud Director via PowerCLI

Bit of a quick post this, but hopefully useful to others.

I got asked recently if there was an easy way to set Guest Customization options for VMs hosted in vCloud Director via Powershell/PowerCLI. It turns out there is an extremely simple way, but the syntax is a bit awkward so figured it would make a good/quick blog post.

The Guest Customization settings are available as one of the ‘Section’ entries returned by accessing the ExtensionData properties on a CIVM object. Once connected (Connect-CIServer) you can see this from PowerCLI:

The ‘trick’ is that there are typically 5 sections (one each for OvfVSSD, OvfMsg, network connections, guest Customization and VMware tools). I’ve seen some approaches that rely on the ‘guest Customization’ setting always being found at the Section[3] index in the ExtensionData collection, but this could easily change in future and break any functionality relying on this. A much more reliable way of finding the guest Customization section values is:

But how about if you need to change/update a setting, luckily there is a method provided (UpdateServerData) which does exactly this. So if we want to (for example) change the ‘CustomizationScript’ setting to “echo “Hello World!” we can:

You can change other settings using the same method (e.g. ComputerName or Domain join settings).

Note that for many changes the VM must be powered off, and you may need to ‘Power On and Force Recustomization’ too.

As always, comments & feedback appreciated.
