Why Docker? What’s all the hype about?

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/
