Docker is an open-source containerization software that enables developers to build, ship, and run applications using containers. Containers are lightweight, isolated environments that bundle an application with all its dependencies, ensuring it runs consistently across different environments.

Docker commands are the instructions used to interact with Docker, a popular containerization platform. These commands allow users to manage containers, images, networks, and volumes, enabling efficient application deployment and management.

Jenkins is one of the most popular open-source automation tools for building, testing, and deploying applications. When combined with Docker, Jenkins becomes even more powerful, enabling consistent, isolated, and scalable CI/CD (Continuous Integration and Continuous Deployment) pipelines.

Kubernetes is an open-source container orchestration platform designed to automate the deployment, scaling, and management of containerized applications. It provides a robust framework for running distributed systems resiliently, allowing for load balancing, self-healing, and automated rollouts and rollbacks.
