It should be fine but you have to water and fertilize sometimes more than planted trees. There are some excellent forum messages on root pruning that you might want to read. I have all of my trees in pots and they do just fine.

Will Be ok If you let it go in the ground,by buring thr pot,5 inches deep,and drilling holes on bottom side,while plugging bottom holes,to be able to cut the roots in Nov. with a spade and take it inside.
If grown outside ground is very hard to please it and it will drop fruits if you do not.
Hope this will help

Thanks Herman, also I forgot to mention that I put all of them in my garage during the winter.

Your best bet is not going to be Desert King. It does still need quite a bit of sun. This year, the Desert King did not ripen well for me like last year. (Keep in mind that I'm in San Francisco where we don't get much heat, and sometimes foggy days in the summer.) However, my Osborn Prolific was able to ripen sweet and juicy fruit last year easily even in the mist of 2.5 weeks of foggy mild weather. I was astonished. I have heard somewhere on the internet that Osbourne can even fruit in partial shade, but as always, the more sun, the better the fruit.
