I'd love to have 50 upvotes to give to this particular comment. With Docker being so fashionable, too many applications which have strictly no business being containerized are shoehorned into containers (e.g. Confluence). My rule of thumb is: as soon as I have to `docker exec` into a running container because something's wrong, this container needs to be stopped and a VM should be used instead.
