Put differently, Docker is an abstraction on top of low-level operating system tools that allows you to run one or more containerized processes or applications within one or more virtualized Linux instances. It gives programmers, development teams and operations engineers the common toolbox they need to take advantage of the distributed and networked nature of modern applications.” “Docker is an open platform for building, shipping and running distributed applications. use Continuous Integration to automatically build and test Docker containersĭocker’s homepage describes Docker as follows:.
