rockman, there is a fair amount of information on overwintering containerized strawberries here:

It sounds like it is not recommended to try to keep them growing as it will shorten their overall lifespan. If it were me, I would leave them outside until the weather is cold enough to stop growth and put them in dormancy, then move the container into a dark corner of the unheated garage and let them rest until spring. I'm thinking that it would be hard to get enough good lighting in the garage to get production of more than a few small inferior berries in the cold, so not sure it would be worth the effort.
