Default DKA & Hypokalemia

Could anyone explain how this occurs? From my understanding high glucose levels draws K+ out of cells (HypERkalemia), low insulin promotes less shift of K+ in to cells (HypERkalemia), and acidosis causes K+ to shift out of cells (hypERkalemia)....so how does DKA cause hyPOkalemia? From my understanding DK:

High glucose (hypertonicity which cause the shift of K+ to ECF),
Low insulin
Low pH

Hypokalemia in DKA???which book is that pls?your analysis above is correct but

In DKA=hyperkalemia but with low intracellular K+ hence in treatment of DKA,you treat as if hypokalemia to restore the intracellular loss
