Unless you are growing a breba-only variety, like "Desert King" you will probably want to pinch off all breba, and only allow main-crop figs to develop. You are in Zone 5b. Try growing early ripening varieties, and forget those varieties that need hot, sunny, dry climates and require long seasons to ripen figs. Prune to establish the basic framework of branches, then pinch to control growth and direct energy into ripening just main-crop figs. Stop all fert's. by mid July, at the very latest. If you use organics, there will be enough residual fert's left in the medium to carry figs over until dormancy.
Follow pinching instructions in reply #2, and stay away from high nitrogen fertilizers which delay onset of main-crop figs. If you can, you could try pushing and extending the season by doing the 'fig shuffle', both in the Spring and Fall. You may get a few weeks more growing time by doing the "in at night, and out during the days". I doubt you are growing grounded trees in 5b, so the shuffle might be an alternative for late croppers. It may just get you some ripe figs instead of "almost ripe" before onset of dormancy.
Make sure your containers are large enough to support root growth, and restrict water at the roots as figs ripen. Don't forget the top dressing of granular limestone. Figs hate acidic mediums.
Good luck, and good growing.
