This pull request updates the SDK's Docker build process and related configuration to improve image security and flexibility. The main changes include switching to hardened base images from a private registry, splitting PostgreSQL images into build and runtime variants, and refining the Dockerfile to streamline dependencies and user creation.
Container base image and registry updates:
dhi.iofor improved security (packages/sdk/docker-bake.hcl).dhi.io) before building images (.github/workflows/sdk.yaml).PostgreSQL image improvements:
dhi.iofor production, with configurable major version support (packages/sdk/docker-bake.hcl,packages/sdk/Dockerfile). [1] [2] [3]packages/sdk/Dockerfile).Dockerfile dependency and user management:
passwd), then remove them immediately after use to reduce image size and attack surface (packages/sdk/Dockerfile). [1] [2]lua5.4andxz-utilsfrom the runtime dependencies (packages/sdk/Dockerfile).Build process enhancements:
/usr/local/bindirectory exists before extracting binaries, improving reliability during the build (packages/sdk/Dockerfile).forgebinary is included, copying it from a prior build stage instead of downloading it again, which improves build caching and consistency (packages/sdk/Dockerfile).
