- Denzel 9y agoSure, and what of the users' applications running in the Docker container. It's just not the type of "run anywhere" I was expecting based on the marketing/hype. And the more people kept saying "package once, run anywhere" the more I began to wonder how Docker was able to accomplish that without being a VM. Short answer: they don't. I'm not saying Docker isn't valuable. It is. I just wish it was documented more readily, without having to sift through jargon, that Docker containers must run on a compatible kernel. Essentially, I found it confusing how Docker was sold as a lightweight VM.
