Docker is an open-source platform that enables developers to build, ship, and run applications in containers. Containers allow for lightweight virtualization by packaging applications with their dependencies into isolated environments, ensuring consistent behavior across different systems.
Key Features ✅
- Containerization: Applications run in isolated containers with their own file systems, CPU, memory, and other resources.
- Portability: Easily deploy applications across cloud platforms, servers, or local machines.
- Scalability: Quickly scale applications up or down based on demand.
- DevOps Integration: Streamlines development, testing, and deployment workflows with tools like Docker Compose and Kubernetes.
Use Cases 📦
- Microservices Architecture: Package each service into a separate container for modular development.
- Continuous Integration/Deployment (CI/CD): Automate testing and deployment pipelines using Docker images.
- Development Environments: Create consistent development setups for teams.
Why Choose Docker? 💡
- Speed: Start applications faster than traditional virtual machines.
- Resource Efficiency: Share OS resources among containers, reducing overhead.
- Version Control: Manage application versions through Docker images and tags.
