What is Docker?
Docker is a containerization platform that is free and open source. It allows developers to package programs into containers, which are standardized executable components that combine application source code with the OS libraries and dependencies needed to run that code in any environment. Containers make distributing distributed programs easier, and they're becoming more popular as companies move to cloud-native development and hybrid multi-cloud setups.
Developers can develop containers without Docker, but the platform makes building, deploying, and managing containers easier, simpler, and safer. Docker is a toolkit that allows developers to use a single API to build, deploy, operate, update, and stop containers using simple commands and work-saving automation.
Why use Docker?
Improved—and seamless—portability:
Docker containers run without alteration across any desktop, data centre, or cloud environment, whereas LXC containers frequently reference machine-specific configurations.
Even lighter weight and more granular updates:
Multiple processes can be combined in a single container with LXC. Each Docker container can only run one process at a time. This allows you to create an application that can keep operating while one of its components is updated or repaired.
Automated container creation:
Docker may create a container based on the source code of an application.

Container versioning:
Docker can keep track of different versions of a container image, roll back to prior versions, and figure out who produced it and how. It can even upload only the differences between an old and a new version.
Container reuse:
Existing containers can be utilized as basic images, or templates, to create new containers.
Shared container libraries:
Thousands of user-contributed containers are available in an open-source registry for developers.
Docker containerization is now supported by Microsoft Windows Server. Most cloud providers also provide services to assist developers to create, shipping, and running Docker-based applications.
