Docker is an open-source tool for containerization that streamlines application creation and deployment through the use of containers. Containers enable us to bundle all parts of an application into a single package for deployment.

This tool makes it easy for different developers to work on the same project in the same environment without any dependencies or OS issues. Docker functions similarly to a virtual machine, however, it enables applications to share the same Linux kernel.

Docker offers many advantages for developers and DevOps teams. Some of these advantages include:

Being highly demanded by both large and small companies.

Providing isolation from the main system.

Streamlining configuration.

Providing access to thousands of pre-configured images through Docker Hub.

Supporting many CI tools like Travis and Jenkins.

Allowing developers to concentrate solely on writing code.

Simplifying deployment management for operations teams.

Docker is frequently utilized in conjunction with Kubernetes, a robust container management tool that automates the deployment of Docker containers. While Docker is utilized to package, isolate, and distribute applications in containers, Kubernetes acts as the container scheduler responsible for deploying and scaling the application.
