A method for forming a virtualization system image. A specification of an expressed end state of a virtualization system image is analyzed. The specification is decomposed into lower level specifications and the lower level specifications are decomposed into idempotent operations. The virtualization system image corresponding to the expressed end state is assembled by processing the idempotent operations. The expressed end state, decomposed lower level intents, and decomposed idempotent operations are codified into a decomposition hierarchy. The decomposition hierarchy is query-able such that, for a given intent, an idempotent operation is returned. An idempotent operation code library is query-able such that, for a given idempotent operation, a corresponding set of executable code is returned. An image builder executes the executable code. When all of the idempotent operations have been successfully executed, the virtualization system image is complete. A virtualization system image is deployed to computing nodes that constitute a computing cluster.
