The main problem people have with containers is keeping them cool, the top, green part of the plant, loves the sun, but the roots where the tubers grow like it cool and dark, a strip of shading material in front of the pots can work wonders.
Potatoes are also great as a first crop on a bit of reclaimed land. That is partly because they grow strongly enough to suppress most weeds, but also not only do you dig to plant them, you then earth them up and finally dig to harvest, so weeds take a real bashing and the ground is well turned for the next crop. I also mulch heavily with lawn mowings which adds still more to the effect.
