Docker

Docker is an open-source containerization platform used to build, package, and run applications in isolated environments called containers. It enables developers and DevOps engineers to deploy applications consistently across different systems by bundling code, runtime, libraries, and dependencies together.

Features of Docker:

• Provides lightweight and portable containers for application deployment.
• Ensures consistency across development, testing, and production environments.
• Supports rapid application scaling and easy resource management.
• Integrates well with CI/CD pipelines for automated builds and deployments.
• Allows applications to run independently of the underlying host system.

To check if Docker is installed and running, use the following commands:

Check Docker version:
$ docker --version

Users are responsible for securing container images, managing access permissions, and following best practices when running containers in production environments. Improper configuration may lead to security risks. Docker is recommended for development, testing, and scalable application deployment.
