One reason to use containers over VMs is that building, updating and extending containers is far easier and more maintainable than full virtual machines.
Containers give you the ability to layer the pieces you need on top of each other, so you are only responsible for the parts that you maintain. No need to rebuild an entire VM image every time one piece of the stack is updated.
Distribution of containers is also far more efficient than full virtual machines (especially important in a highly distributed environment).
