Worked on optimizing Docker image builds for the localstack/localstack repository by introducing the --no-install-recommends flag during the installation of gcc and g++ in the builder stage. This approach reduced the Docker image size and eliminated unnecessary dependencies, leading to faster deployment times and improved CI caching efficiency. The work focused on containerization and DevOps practices, utilizing Dockerfile modifications to streamline the build process while maintaining feature parity and stability. Documentation and contributor comments were updated to clarify the rationale behind these changes, ensuring transparency and maintainability for future contributors working with Docker and related container technologies.
