I am thinking about making a raised garden bed, as I am renting and digging up the backyard is not possible. I'm wondering about drainage in the boxes. Do I need to drill holes in the bottom or the sides? I want to grow my own vegetables, and is it possible to make them portable?

Yes, drainage holes would be needed and best. If drainage holes would be difficult, you can try a drainage layer. This would be a layer of rocks at the bottom where excess water can run into and not swamp the roots of the plants.
