Description: Build arguments are variables that can be passed at build time to customize the Docker image building process. These arguments allow developers to modify the behavior of the image build without changing the Dockerfile. They are defined using the ‘ARG’ instruction in the Dockerfile, allowing default values to be set that can be overridden at build time. This is particularly useful for handling environment-specific configurations, such as credentials, paths, or software versions, which may vary across different environments. By using build arguments, flexibility and reusability of images are enhanced, as multiple variants of a base image can be created without maintaining multiple Dockerfiles. Additionally, build arguments are temporary and only available during the build process, helping to maintain security by not exposing sensitive information in the final image. In summary, build arguments are a powerful tool in the Docker ecosystem that allow developers to customize and optimize the image creation process efficiently and securely.
