-`Auto` | Currently `Recreate`. This might change to in-place updates in the future.
-`Recreate` | The VPA assigns resource requests on pod creation as well as updates them on existing pods by evicting them when the requested resources differ significantly from the new recommendation
-`Initial` | The VPA only assigns resource requests on pod creation and never changes them later.
-`Off` | The VPA does not automatically change the resource requirements of the pods. The recommendations are calculated and can be inspected in the VPA object.
