> why do I need to wrap THAT of all things in a container?

If you can't see a reason why, then you probably don't need to. You probably have different needs than other people.

Many people use Docker not because of what they're doing inside of the container, but because it is convenient for tangential activities. Like lifecycle management, automation, portability, scheduling, etc.

I have several static sites in Docker containers in production. We also have dozens of other microservices in containers. We could do everything the same way, or we can one-off an entirely separate architecture for our static sites. The former makes more sense for us.
