Docker is an open-source platform that automates the deployment of applications inside lightweight, portable containers. These containers include all the necessary dependencies to run an application, ensuring consistency across different environments.
Key Features of Docker
- Containerization: Package applications with their code, runtime, system tools, and libraries into isolated containers.
- Lightweight: Containers share the host system’s kernel, making them more efficient than traditional virtual machines.
- Cross-Platform: Run Docker containers on any operating system that supports it (Linux, macOS, Windows).
- Orchestration: Use Docker Swarm or Kubernetes to manage multi-container applications at scale.
Use Cases
🔧 Development: Streamline workflows with consistent environments.
🧪 Testing: Isolate tests to avoid conflicts between projects.
🚀 Deployment: Deploy applications quickly and reliably to production.
