Docker containers are lightweight, portable, and self-sufficient units that package an application and all its dependencies, allowing it to run consistently across different computing environments.
Key Features:
- Isolation: Each container runs in its own environment, isolated from others, which helps avoid conflicts.
- Portability: Containers can run on any system that has Docker installed, making them highly portable.
- Efficiency: They share the host system's kernel, which makes them more resource-efficient compared to traditional virtual machines.
Use Case:
Containers are commonly used for deploying applications, microservices, and development environments, enabling developers to build, ship, and run applications quickly.
