How do I get baby to sleep in crib?

So my little one is about to turn 8 months in a few days and refuses to sleep in his own crib. I try every night for at least an hour to get him to fall asleep (he’s extremely drowsy when I try) but he screams bloody murder and doesn’t know ho to self soothe. The second I put him in our bed he passes out. 😭 is there tricks I can try?
