Summary

Restructures the build into a chain — postgres → minimal → standard → coldfront — where each
flavor builds FROM the one below it instead of rebuilding the base. Adds a PostgreSQL-only
postgres image and a coldfront image at the ends of that chain. CI builds it in per-flavor
waves: every major/arch of one flavor in parallel, then the next wave starts from the digests
the previous one pushed.

Changes

  • Dockerfile — four chained stages; each parent is a build ARG defaulting to the stage above,
    so a local build still produces the whole graph while CI points each wave at a pushed image.
    Per-stage packagelist ARGs (a shared one can't survive chaining).
  • postgres — spock-independent, so no spock segment in its tag or job name. Owns the
    PGDATA/USER/ENTRYPOINT tail; minimal now adds only spock, snowflake and lolor.
    pgedge-postgresql-server is pinned explicitly rather than arriving transitively.
  • coldfront — installs prebuilt packages, no compilation. coldfront-entrypoint.sh wraps
    the standard entrypoint: emits GUCs as -c flags under postgres, renders a 0600 config
    from COLDFRONT_* env under the tools. Explicit -config > read-only COLDFRONT_CONFIG >
    rendering; the packaged config is never written to.
  • CIbuild-flavor/merge-flavor composite actions replace duplicated steps and derive
    their ARGs from the matrix cell. Wave jobs block only on upstream failure, since an empty
    matrix legitimately skips a job. pgedge_image_republish preserved.
  • Teststests/main.go accepts postgres and gates the spock/lolor/snowflake cases.

Verification

55/55 jobs green; 18 tags with attestations, cosign 18/18 against the pinned identity.

  • Layer chain: postgres 6 → minimal 8 (6/6) → standard 11 (8/8) → coldfront 15 (11/11),
    identical across all majors and arches; both spock lines share one postgres base per major.
  • Minimal and standard unchanged from main: package sets match exactly (181 = 181, 347 = 347;
    only newer OS errata differ), pgEdge versions byte-identical, same runtime GUCs and extensions.
  • Coldfront works end to end against live Lakekeeper + SeaweedFS: Iceberg table created
    through the catalog, 1000 rows written, reads/UPDATE/DELETE verified; the archiver tiered two
    partitions through all six phases and all 600 rows still read back (500 cold, 100 hot).
  • make test-image passes on all 18 images, 0 errors.

📝 Walkthrough

Walkthrough

The change introduces chained PostgreSQL image flavors, ColdFront support, native architecture build waves, digest-based manifest merging, updated package manifests, and flavor-aware runtime tests.

Changes

Image flavor pipeline

Layer / File(s) Summary
Flavor ancestry and image inputs
Dockerfile, pgedge.docker-bake.hcl, scripts/build_pgedge_images.py, packagelists/*
The image stages chain from PostgreSQL through minimal and standard to ColdFront. Build planning emits architecture and flavor matrices. Package manifests add PostgreSQL and ColdFront packages and remove inherited packages.
ColdFront image and runtime behavior
coldfront-entrypoint.sh, tests/main.go, Dockerfile
The ColdFront entrypoint renders configuration, injects PostgreSQL and DuckDB settings, dispatches ColdFront tools, and delegates other commands. Tests cover ColdFront startup and configuration behavior.
Native build and manifest actions
.github/actions/build-flavor/action.yml, .github/actions/merge-flavor/action.yml
Composite actions build and validate architecture images, publish digest artifacts, assemble signed indexes, and refresh mutable tags.
Wave-based workflow orchestration
.github/workflows/build_images.yaml, .github/workflows/pr_test_latest.yaml, .github/workflows/test_images.yaml, Makefile, .gitignore
The workflow plans and executes dependent PostgreSQL, minimal, standard, and ColdFront waves. Test matrices recognize the new flavors. Build scratch files are ignored, and the configured Buildx builder can be printed externally.

Priority: ➖ Normal

Merge Risk: ⚪ Minimal · up to 874c7

The flavor mappings are consistent with the supported image-test flavors, with no remaining merge-blocking risk.

Disable credential persistence on all checkout steps.

actions/checkout stores GITHUB_TOKEN in .git/config by default. The build jobs send the workspace to docker buildx bake as the default context, and this repository has no .dockerignore, so .git/config is included in the BuildKit context. Set persist-credentials: false on all eight checkout steps.

In `@coldfront-entrypoint.sh`:
- Line 99: Normalize a leading command-line option by prepending the postgres
command before the condition that checks ${1:-} for "postgres". Update the
entrypoint flow around the postgres dispatch so option-starting invocations
enter the same PostgreSQL setup path and preserve the required preload and
DuckDB settings.
- Around line 131-134: The local PostgreSQL DSN assembly in
coldfront-entrypoint.sh must produce a valid libpq keyword-value string for
values containing spaces, single quotes, or backslashes. Update the construction
around COLDFRONT_LOCAL_PG_DSN to quote and escape COLDFRONT_SOCKET_DIR,
POSTGRES_DB, and POSTGRES_USER, while preserving the existing defaults and
application_name; add coverage exercising spaces in the database and role names.
