PLASTIC CONTAINERS GARDENING

What Size of container is ideal for Raspberries. container gardening planting?
I was considering doing a bunch of little raised beds for raspberries made out of scrap industrial ductwork, only I can’t find the scrap ductwork and I’m thinking of moving in a couple years. I got the idea that maybe a container would better suit my needs.
What is an ideal size of container to grow fruiting raspberry bushes?
There are rigid black plastic storage containers on sale at home depot right now. They’re 18 gallons at about 20 x 16 x 16 inches. Would these do the trick with one plant in each container?
I would drill holes in the bottom of the things for drainage and put 2 inches of mulch at the top.
I already have a bunch of gardening soil, mushroom compost, and topsoil laying around in bags. Could I use that in the containers? Should I mix some sand or something in with it to make it drain better?
Container growing
Single raspberry plants can be grown in 38cm (15in) diameter containers of 80 percent multipurpose compost and, to add weight for stability, 20 percent loam-based potting compost, training the canes up bamboo poles.
Keep the compost moist (using rainwater in hard water areas) and feed with a liquid general-purpose fertiliser on a monthly basis during the growing season.
