You can grow leeks in a container. Make sure that your container is 12" deep and has drainage holes. Fill with a mixture of potting soil and compost to a level about 4" below the top of the container, which will give you room to blanch the leeks later by adding layers of compost or soil. In hot weather you should keep them out of direct sun.
