Docker can be described as a containerization framework that bundles all of our applications into a single package, allowing us to run them in any environment. This means that our application can run smoothly in any environment, making it simple to build a production-ready app.
This framework bundles the appropriate software in a file system that includes everything required to run the code, including the runtime, libraries, and system resources.
Containerization technology, such as Docker, uses the same OS kernel as the machine on which it runs, thus making it very fast. This means we only need to run Docker once, and the rest of the process will run smoothly because the operating system of our system is already running.
