Docker Container is software that packs up all the code, system tools, libraries, and its other dependencies to run in different computing environment also. Docker containers run on a docker engine to provides portability, efficiency, and security for applications.

Docker Container can support Linux, Windows, Cloud and Serverless applications also. Docker Containers function different from Virtual machines but have used for resource allocation and isolation. Multiple Docker containers can share the same OS kernel but each virtual machine needs a separate Operating system kernel. This makes Docker container light-weight and works faster compared to VMs.
