Fog can't be contained in a container, it fill the entire scene. Some solutions:
- Use a large distance value, something like 1000 or more. That way, the fog's effect
can be 
minimised to a negligeable level close by.
- Use a ground fog, but have the up vector been horizontal. Use a large negative value
for the 
altitude. You may need to use several fogs to surround the scene.
- Use a hollow torus with a very large main radius, say 10000 or more, and fill it
with media.
