World No 2 Djokovic - who has won the Indian Wells title five times, including in each of the last three years - won 6-4 7-6 (7/5) against the Briton.
The Serbian broke Edmund in the first game before seeing out the first set in 42 minutes but Edmund rallied in the second.
The 22-year-old secured the first three games before Djokovic fought back to take the second set to a tie-break, which he ultimately won.

Rafael Nadal made light work of Argentina's Guido Pella to secure a third-round tie against fellow Spaniard Fernando Verdasco.
