What is 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 ship it all out as one package.

Using Docker, developers can package their applications into lightweight, portable containers that can be easily distributed and run on any platform that supports Docker. This makes it easier to develop and test applications, as well as to deploy them to production environments.

Docker also provides a number of other benefits, such as:

• Isolation: Containers are isolated from one another, which means that they can run side-by-side on a single host without interference.
• Lightweight: Containers use fewer resources than traditional virtual machines, making them faster and more efficient.
• Scalability: Docker makes it easy to scale applications up or down, as you can easily spin up new containers as needed.

Overall, Docker provides a convenient and efficient way to package, deploy, and run applications, making it a popular choice for many developers and organizations.
