I live in zone 7 in NC and presently have a potted DC that has fruit on it. Yes, it is possible to get fruit. However, it is not easy. My two DC's that have fruited took 2 to 2.5 years to produce a flower. Even so, the amount of time your plant needs to produce fruit will depend upon the water regimen, fertilizer, amount of sun, size of the pot, temperature control in greenhouse, etc. Even after the flower appears, if your plant does not have sufficient growing conditions, the flower will likely choke. You will need months to ripen the fruit. Unfortunately, my two DC's both produced flowers around Thanksgiving 2012 and 2013, when I had no sun to offer them. The first plant was too weak to mature the fruit. The current plant's fruit looks strong, but the leaves look pitiful due to low humidity indoors. The 10-foot ceiling should be adequate for the DC.
