Ask your local gardening center about special varieties, esp. tomatoes which are specifically for pots. My brother started "pot" tomatoes early last spring, from seed, and had them 4-5 feet on his front deck all summer through early fall. They were delicious. The babies I took from him and put in pots didn't do well, though.We live in hot and dry plus high altitude sun, so I had them in partial shade (facing east as his did, but more shade). By the time they produced tomatoes it was obvious they had been in need of more sun, smaller pots, and more even watering.:-)

According to the search I did at our fav. seed company's catalogue, all of the veggies listed HERE are "container" plants.
