So back to my original question, what now?
Subject to the size and your willingness to water you can grow almost all veg in containers.
In some garden centres they are selling grow bags for lots of veg that most people would not even try.I am not saying buy them they are costly,but pop along to one and see if you can find the bags I mean (I saw them in my local Dobbies)
This will give you the confidence to try to do your own.
They even have bags for runner beans :!:
Every year I use containers and very successfully.
Look up what type of soil each veg likes and fill your container with that mix.
Look for a place thats not always in full sun,and not too windy.
Use stakes if the end product is tall.IE. tommatoes and use a mid season fillip(tomorite is good for lots of veg in containers) during the growing season.
But the most important water well but never flood.
