Hey, I just got my puppy today too! He is right now sleeping in his crate (5AM) and is sound asleep! The thing I did was get a crate with a divider so that he doesn't have room to go on the other side of the crate to pee/poop. He has enough room to stand up turn around and lay down. I would suggest you get a divider! Also, for the whining part, I suggest you tire your pup out before you get him to go into the cage, you want him to know that the cage is a safe place for him to be. What I did was play with his chew toys and let him tire himself out before I lured him into the cage with his stuffed animal that he sleeps with. I would say my pup is a good sleeper, but maybe tomorrow he can be the opposite!
