Herb Gardening in containers isn't complicated. Containers can be whatever suits your eye and pocket book, from big clay pots, lighter weight plastic pots and windowboxes, to wine barrels, recycled pulp containers, wooden boxes or even big drain tiles you may have available. Just be sure you have large enough containers to hold the full-grown plants and their root systems. For good drainage and air circulation, you should have a little air space between container bottoms and the ground: use wedges or flat stones or a plant stand to raise them up a bit.
