Docker
Docker is a tool designed to make it easier to create, deploy, and run applications by using containers. Containers allow a developer to package up an application with all of the parts it needs, such as libraries and other dependencies, and deploy it as one package. By doing so, thanks to the container, the developer can rest assured that the application will run on any other Linux machine regardless of any customized settings that machine might have that could differ from the machine used for writing and testing the code.
Docker Enterprise Edition is the container management tool offered by popular container vendor Docker. Originally a competitor to Kubernetes, Docker Enterprise has been positioned as more secure by default than Kubernetes. Eventually, as Kubernetes and its commercial variants took over the enterprise container management space, Docker began offering Kubernetes as an option for deploying containers, along with Docker’s security and management. Because Docker containers are the standard for system level images, Docker Enterprise will see some amount of success. The additional security protections offered are not well-matched by other competitors, but as we’ve seen across DevOps, that can change quickly.
