The next question on your mind is probably “How can I contribute?“. Well, with the correct tools and some VMware PowerCLI knowledge, it turns out that this is not too difficult. What follows is my first attempt at contributing to the Desired State Configuration Resources for VMware.
The “Principles of Operation” in the title is in fact just an expensive expression for “How do I use this stuff ?”. In this post I will try to show you how you can use the vSphereDSC module, as a user, and as a contributing developer. On the side, it also shows you how you can use these vSphereDSC resources.
The vSphereDSC module contains a set of DSC resources to can be used to configure a vSphere environment. These DSC resources can be used against any vSphere Server, beit a vCenter or an ESXi node. On the condition of course that the selected resource is supported on the vSphere Server.
For “users” of the vSphereDSC resources, the post will show how to automate keeping the module up to date and how to manage the life cycle of the Configuration files that are build on the vSphereDSC resources.
For those of you that want to contribute to the development of the vSphereDSC module and it’s resources, this post will also show how you can automate the testing phase. In a first instance through a number of PowerShell scripts, in a later phase through the use of a build server.
Since WMF 5 has been made available in preview, and still is in RTM at the moment I’m writing this, there have been constant changes to the way I was writing the DSC resources for vSphere. Since the February 2016 WMF 5 release, I now have a (somewhat) stable, working class-based solution. At least, that is what my initial tests seem to indicate.
This intro for my vSphereDSC series, will lay out the playing field. I’ll explain the concept I’m using, show some of the issues I encountered and explain the layout of the vSphereDSC Resource module.
