readystack/postgresql:18.4-CE-debian-bookworm-r2

A hardened, cosign-signed, offline-rebuildable build of github.com/postgres/postgres REL_18.4 (PostgreSQL 18.6, PostgreSQL License), built clean-room from official upstream source by ReadyStack⁠.

⁠What you get

• Docker Scout — re-checked daily; today's grade and the reason for it are at https://readystack.dev/queue⁠.
• Signed — cosign signature by the ReadyStack release key; verify with cosign verify --key https://readystack.dev/keys/cosign.pub --insecure-ignore-tlog=true readystack/postgresql:18.4-CE-debian-bookworm-r2.
• Built from source, non-root.

⁠Which tag should I pull?

This image follows the ReadyStack release-tag convention:

• The current release is 18.4-CE-debian-bookworm-r2 — the release on sale at readystack.dev. Release tags use the pattern <upstream-version>-CE-<base-os>-r<N>; the current one is hermetically built, signed, attested, and supported under your ReadyStack agreement.

• Earlier release tags (an older version or revision in the same pattern) are superseded. They stay pullable so existing deployments can pin them, but they are no longer patched or re-graded: move to the current release. A superseded release's build kit is available through support.

• Any tag beginning with internal- is an engineering-pipeline artifact published for build observability. It is unsupported, may change or disappear without notice, and must not be used in production.

# ✓ current release
docker pull readystack/postgresql:18.4-CE-debian-bookworm-r2

# ✗ unsupported (do not pull)
docker pull readystack/postgresql:internal-...

Each release tag is signed; verify with cosign verify --key https://readystack.dev/keys/cosign.pub --insecure-ignore-tlog=true readystack/postgresql:18.4-CE-debian-bookworm-r2 (ReadyStack keeps signatures off the public transparency log, so the check is key-only). Support: [email protected]⁠.

⁠Deployment

Single container. A self-contained PostgreSQL 18.6 object-relational database server, compiled from source (./configure && make world-bin && make install-world-bin). The image IS the complete running instance — PostgreSQL itself IS the database, so there is NO external database and NO sidecar. On first boot the entrypoint runs initdb to create the cluster under PGDATA (/var/lib/postgresql/data), then runs postgres in the foreground. Runs fully NON-ROOT as the postgres user.

docker run -d --name postgresql -e POSTGRES_PASSWORD=YOUR_SECRET -p 5432:5432 -v pgdata:/var/lib/postgresql/data readystack/postgresql:18.4-CE-debian-bookworm-r2
