Optimizing Docker image size is crucial for efficient deployment and orchestration in DevOps.Reducing image size improves speed, storage costs, CI/CD pipelines, and security.Starting with a minimal base image like Alpine Linux can significantly reduce overall size.Multistage builds help eliminate unnecessary dependencies in the final image.Avoid installing unnecessary dependencies by only including what is essential..dockerignore helps exclude unnecessary files and directories from the build context.Optimizing layers in the Dockerfile by combining commands reduces image size.Cleaning up temporary files after installing packages helps maintain a minimal image size.Using smaller language runtimes and compressing layers further reduce image size.Regularly auditing images and using tools like Docker Image Scanning improve security and efficiency.
