Why I use it
Its job in the stack
I use Docker when a project needs the same dependencies and runtime behavior across machines. A container makes the environment inspectable and repeatable, which is far better than a setup that only works on the original developer’s laptop.
Containers are most useful when they reduce ambiguity. They should not be added to a static site or a simple script merely to make the project look sophisticated.

Limits
What it does not solve
Images, volumes, networking and updates create their own operational burden. The deployment model must justify it.
