Dockerfiles provide business applications with more flexibility and mobility. Dockerfiles are used by IT companies to bundle programs and their dependencies in a virtual container that may operate on bare metal, in public or private clouds, or on-premises. Numerous apps, worker tasks, and other activities can operate independently on a single physical computer or across multiple virtual machines using containers. Kubernetes is an open-source solution for automating the management and orchestration of Dockerfile-based containerized applications.
