Yes you can grow rhubarb in a pot. I found out accidentally. I bought two more plants but before I could plant them I broke my leg. I had a large pot, 24-30" across which was prepared for flowers. I ended up planting them in the pot thinking I might be able to plant them in the ground the next year. The pot is at the north east corner of my house so it gets sun but also shade later in the day. The next spring I was surprised to see the rhubarb in the pot was growing faster than the established ones in the ground. This year, after five years they are still growing faster. I was cutting my first rhubarb while other people's was only about 6". I have two plants in the planter. The first winter I covered them with a piece of fleece fabric. Second winter I put a little straw on them. The last couple years I haven't covered them at all. I live in Iowa so they do get covered with snow. The plants are bushy and healthy. I will never plant them in the ground again.
