Learn Docker
Docker is a popular platform used for developing, shipping, and running applications. It allows developers to package their applications and all their dependencies into containers, which can then be easily deployed across different environments, such as development, testing, and production, without worrying about inconsistencies between environments.
Containers are lightweight, standalone, and portable, containing everything needed to run an application, including code, runtime, system tools, system libraries, and settings. Docker uses containerization technology to ensure that applications run consistently across different environments, regardless of the underlying infrastructure.
Overall, Docker simplifies the process of building, deploying, and managing applications, making it a valuable tool for developers and DevOps teams.
Key features of Docker:
• Containerization: Docker allows you to package applications and their dependencies into lightweight, portable containers.
• Isolation: Docker containers provide process and resource isolation, keeping applications and services separate.
• Portability: Docker containers can run on any system that supports Docker, regardless of the underlying OS or infrastructure.
• Version Control and Reusability: Docker images are versioned, allowing developers to track changes and to roll back.
• Scalability: Docker makes it easy to scale applications by spinning up additional containers when needed.
• Cross-Platform Support: Docker runs on various platforms, including Windows, macOS, and Linux.
• Continuous Integration and Continuous Deployment (CI/CD): Docker integrates well with CI/CD pipelines.
• Orchestration Support: Docker integrates with orchestration tools like Kubernetes and Docker Swarm to manage containers.
