Herbs: Growing Lavender in containers, 0 by sempervirens

I have no problem growing lavender in the garden in zone 6 but I would like to move a few plants to cement planters that border the herb garden. The containers are 15" long X 8" X 8". The interior planting area is less because they have a V interior space rather than a rectangle. So the planting space is shallow, only 6" at the deepest and 3" at each side. Will they survive with such a shallow root space? And if I can grow them will they overwinter in the planters or would I have to consider them annuals? Right now I have Irises and chives growing in them and they overwinter fine.

The photo shows the lavender plant dormant behind the planter now.
