Docker is a company and a suite of tools designed for managing containers, which are lightweight modular components that can be deployed and scaled using sophisticated orchestration tools like Kubernetes.
To a five year old, I would say that it's a tool for making developer's lives more consistent and reliable...after they get through the learning curve. :)
Uh...neither of these explanations good. It's tough to ELI5 without saying the words "container" or "orchestration", which are their own beasts.
Thanks a lot.
