I don't see the benefit either. I believe Netflix made this idea popular with sidecar containers as a way to add

to container stacks.

I understand that the idea might be popular among developers as it is easier to just add a database container to your stack rather than dealing with the db admin. I don't know if Netflix ever recommended databases as sidecar containers. But I have seen it in the wild where dev followed the Netflix model. I sometimes hear people arguing that they have to manage containers anyway so it would be less overhead to manage the db as a container as well.
