I have a cutting from next door in 45cm wide by 60cm high pot, it had about 4 canes 2 years ago and now has quadrupled and always does well but it does have a saucer and is watered a lot, my next door neighbour out here in the ground and it has hone mad, but does not seem to have run everywhere.
I also have black cane bamboo (unsure of correct name) This one came from a popular online centre and was very small with maybe 2 9cm canes in, in a pot that is 30cm wide by 25 deep it has grown very quickly by new canes, roots do not seem too bad tbh. I have taken some out of this pot and put it in the ground in the lawn, so I can cut it with mower if need be.
my conclusion is if you are going to keep them in pots make sure they get lots of water and the larger the pot the better I have found. ( unless very small specimens)
lets not forget that they are a true grass so treat them as it and they will grow
