Docker-Container

Docker containers are isolated runtime environments for applications that efficiently share resources and ensure portability. They contain the application along with all dependencies in a package that runs consistently on any system with Docker. Containers start quickly and use fewer resources than virtual machines since they share the host system's kernel. With Docker, you can scale, version, and deploy applications in different environments.
