Docker, or containerization in general is not a system that only helps you manage dependencies and isolation. It's about dependencies management, isolation (to a degree), fast and expectable deployment, automatic scaling and so on. Now days, application backend are expected to run on multiple nodes. Sure, you can manually code your app to automatically deploy/update itself on multiple servers and so on, but that is a huge task, and the maintenance responsibility comes with it is even bigger. Containerization platform such as Docker and Kubernetes provides a standard operating environment for operators and developers to manage the lifecycle of a scalable application, IMO that's where the gold is. Dependency management and isolation etc is just a natural part of that. Of course, you're still responsible in creating a scalable application, but once you did that, deploying the application will be as simple as running a `git push`, then a remote system takes over, creating a container image according to your Dockerfile, and then deploy those containers onto necessary amount of servers. It all happens automatically, like a dream :)
