DOCKER
Docker is an open-source platform that allows developers to automate the deployment, scaling, and management of applications inside lightweight, portable containers. These containers are self-sufficient and contain all the necessary dependencies to run the application, making it easy to deploy the same application consistently across different environments, from development to production.
Key concepts of Docker include:
1. Containers: Docker containers are isolated environments that package applications and their dependencies together, ensuring consistency and reproducibility.
2. Docker Image: A Docker image is a lightweight, standalone, and executable software package that includes the application's code, runtime, libraries, and other dependencies needed to run the application.
3. Dockerfile: A Dockerfile is a script used to define the steps to create a Docker image. It specifies the base image, adds application code, installs dependencies, and configures the container.
4. Docker Hub: Docker Hub is a cloud-based registry service provided by Docker, where developers can find and share Docker images publicly or privately.
Benefits of using Docker include:
- Portability: Docker allows applications to run consistently on any environment, from development laptops to production servers.
- Scalability: Docker containers can be easily scaled up or down, enabling applications to handle varying workloads efficiently.
- Isolation: Each Docker container runs in isolation, preventing conflicts between applications and ensuring better security.
- Efficiency: Docker containers share the host system's operating system kernel, which leads to reduced overhead and faster startup times compared to traditional virtualization.
