If you have a standalone application, then great, maybe docker doesn't add a lot Maybe your application requires xyz lib to be installed via apt or something similar Now docker is useful, as it can maintain that environment easily Now imagine you work in a company with many different teams, and just want a similar way of deploying all services without requiring knowledge of how the application dependency tree looks, just use docker everywhere. That is why imo you see docker used in places it doesn't really offer a benefit, because a standardized way of deploying is a benefit in itself.
