You want big pots, or those sizes that will accomodate the full grown vegetable. I like plastic because a) they're lighter and since they're above ground, less apt for moisture loss than clay (porous) pots. You can grow just about any vegetable in a pot, and many people do container gardening due to limited space. There are plants out there specifically bred for compact container gardening such as squashes, tomatoes, and cucumbers etc. There are many clever ways to grow vertically as well and that saves a lot of space. There are also self-watering pots out there. These are very pricy but if you are even somewhat handy you can make your own. Self-watering is very nice since containers will dry out quicker than regular gardens. Use a nice light soil or seed mix if you don't compost. You may want to feed since if exposed, the rain will leach out valuable nutrients. So now that I've thrown out a whole bunch of stuff, here are some useful links.

Go to Burpee or Johnnies Selected Seeds. Although the climate zones and seeds and such are for the US, these are the ones I know and will give a sense of direction for they types of things that can grow in containers well. Most seed company web sites give planting dates and such. Then, do a search for your country/area and find a comparable seed place to research the vegetable, how to grow it, what it needs, etc., see if there are varieties bred for compactness and more suitable for containers. Then buy local if you want. Go to a local greenhouse to get the plants if you don't want to start from seed.

If you want, buy a cheap set of castor wheels and put on the bottom so you can move it. These things will get heavy when wet and you'll never be able to move it.
