What is Docker?
Docker is a tool designed to make it easier to create, deploy, and run applications by using containers. Containers allow developers to package an application with all of its dependencies, including libraries and other configuration files, into a standardized unit for software development.
Benefits of Using Docker
- Consistency: Ensures that applications run the same way across different environments.
- Portability: Containers can run on any system that supports Docker, regardless of the underlying infrastructure.
- Efficiency: Containers are lightweight and use fewer resources compared to traditional virtual machines.
- Rapid deployment: Containers can be quickly created, started, and stopped.
- Isolation: Applications and their dependencies are packaged together, reducing conflicts between different projects.
