Developer Console - Create a Virtual Machine from a template flow

Background

On the developer console, there is currently no way for a developer to quickly create a virtual machine from a template. Virtual machines can only be created on the administrator console by administrators (cluster admins) and developers. We will be introducing this feature to the developer console with this initiative.

Goals and objectives

Giving developers the ability to quickly and seamlessly create virtual machines from templates. This should reduce the perspective switching cost and improve the overall console experience.

Introducing

  • The ability to create VMs on the developer console

  • The ability to see a virtual machine template option in the main filter on the developer catalog page
