Docker is an open-source platform that allows you to automate the deployment of applications inside lightweight, portable containers. Docker containers share the host OS kernel, making them faster and more efficient.
Installing Docker: Windows/macOS users can download Docker Desktop, and Linux users can use the package manager. Verify the installation after installation.
Running Your First Container: By pulling and running an Nginx web server, you can see the Nginx welcome page on http://localhost:8080 in your browser.
Why Use Docker? Docker provides consistency, isolation, scalability, and CI/CD friendliness, making it a great tool for development and deployment.
