Description: Multi-stage build is a process that optimizes container image size by using multiple phases in its construction. This approach divides the image creation process into different stages, where each stage can have its own set of instructions and dependencies. At the end of this process, only what is necessary to run the application is retained, removing temporary files and dependencies that are not required in the production environment. This not only reduces the size of the resulting image but also improves efficiency in build and deployment time, facilitating more agile resource management. Multi-stage builds are especially useful in development and production environments where speed and efficiency are crucial. Additionally, it allows for cleaner and more organized code, as each stage can be designed to fulfill a specific purpose, making debugging and code maintenance easier over time.
