Why Docker? What’s all the hype about?

2 points by maximization ↗ HN
As a NodeJS developer who's a stranger to the DevOps world I've never really understood the hype around Docker.

In my quest for answers I read many articles explaining why containers are better than virtual machines, but I've rarely used a VM. Is Docker only beneficial for people who come from the VM world?

I wrote an article explaining the benefits of Docker using real-world scenarios that hit it home for me. No buzz words, clear language and with a spice of humor https://maximorlov.com/why-docker-whats-all-the-hype-about/

Containerization is nice because it literally becomes a "write once run anywhere" kind of deal. If it runs on docker, it will run on any* docker.

The true gain is from container orchestration, ie Kubernetes. Scaling becomes nearly trivial. Resiliency is handled like a charm. There are so many pros to containerization with orchestration that libraries full of books have been written about them.
