That depends entirely on what sort of container you're considering.
A pot would certainly not be recommended, no matter how big (and bigger is always better for planting anything in pots - we use 20" diameter for roses), unless you plan to sink it into the ground for the winter. An alternative would be to bring the pot indoors into a coldroom where it wouldn't freeze... however, it would be a real waste of effort to use a perfectly hardy rose such as a 'Hansa' in such a way, given all the maintenance (hauling huge pots in and out) that you would have created... better for a tender rose, if you chose to go that way.
If by "a container", you mean a large, raised, vertical-sided, permanent outdoor planter, then sure, a 'Hansa' would be fine for that.
