Docker Build
Docker Build is a command-line tool and process for creating Docker images from a Dockerfile, which is a text file containing instructions for assembling an image. It automates the creation of container images by executing commands in layers, caching intermediate results to speed up subsequent builds. This tool is essential for packaging applications and their dependencies into portable, reproducible container images.
Developers should use Docker Build when they need to create consistent, versioned container images for deployment, testing, or sharing across environments. It is particularly valuable in CI/CD pipelines for automating image creation, ensuring that applications run identically in development, staging, and production. Use cases include building microservices, deploying scalable web apps, and creating reproducible development environments.
