In example implementations, an apparatus is provided. The apparatus includes a processor, an image creation tool, an operating system (OS) image repository and a secondary node interface. The processor has a first architecture and is in communication with the image creation tool, the OS image repository, and the secondary node interface. The image creation tool is to create an OS image for end nodes having the first architecture. The OS image repository is to store OS images. The secondary node shell is to provide an interface to a secondary node with a processor having a second architecture. An OS image for end nodes having the second architecture is created by the secondary node via the secondary node interface.
