This repository contains the official Dockerfiles and automation tooling for building and publishing Amazon Corretto Docker images across multiple versions (8, 11, 17, 21, 25, 26, 27) and base operating systems (Amazon Linux 2, Amazon Linux 2023, Alpine, Debian). The codebase does not contain a running application but instead acts as a build configuration and CI/CD orchestration layer. The Dockerfiles are meticulously crafted: they verify package signatures via RPM or APT keys, install dependencies (e.g., fontconfig), clean temporary files, and set environment variables. Notable 'slim' variants use `jlink` to produce smaller runtime images by stripping debug symbols, man pages, and header files—a non-obvious optimization. The repository also includes Python scripts (`bin/apply-template.py`, `bin/tag-generator.py`) and shell scripts (`bin/update-dockerfiles.sh`, `bin/test-image.sh`) that automate Dockerfile generation, version propagation, and image validation via container-structure-test. CI/CD is implemented in GitHub Actions and validates images for every push/PR. The repository is the authoritative source for the official amazoncorretto Docker images on Docker Hub and ECR, and its primary purpose is to produce reproducible, secure JDK containers.
