readystack/airflow:3.3.2-CE-ubuntu24.04-r5

⁠What you get

Signature, user and attestations below were measured on the published digest sha256:abe81f278d0992a3b1968e8440e2a3a368da9e464621a712fc74fae261c0586b on 2026-10-28.

• Scan scores — we scan every image we publish every day (an SBOM made with syft, vulnerabilities matched with grype, scored with cerodeo-v1, the rubric ce.rodeo published until 2026-10-26) and record each scan with how its score was derived. This release's first and latest scan: https://readystack.dev/products.html#airflow⁠
• ReadyStack release check — passed at release on 2026-10-28: no fixable critical or high vulnerability (Docker Scout and OSV), a non-root user, SBOM and provenance attached. This is ReadyStack's own test, not a Docker grade; vulnerabilities published since then are in today's result at https://readystack.dev/queue⁠.
• Signed — cosign signature by the ReadyStack release key (fingerprint 04daa92344a52dbc) on this release's index digest sha256:abe81f278d0992a3b1968e8440e2a3a368da9e464621a712fc74fae261c0586b; verify with cosign verify --key https://readystack.dev/keys/cosign.pub readystack/airflow:3.3.2-CE-ubuntu24.04-r5.
• Attestations — An SPDX SBOM and SLSA v1 build provenance are attached to this digest.
• Runs as a non-root user (airflow).
• Built from upstream's published release artifact (https://pypi.org/project/apache-airflow/3.3.2/⁠) by ReadyStack.

⁠Which tag should I pull?

This image follows the ReadyStack release-tag convention:

• The current release is 3.3.2-CE-ubuntu24.04-r5 — the release on sale at readystack.dev. Release tags use the pattern <upstream-version>-CE-<base-os>-r<N>; the current one is signed, attested (SBOM + provenance), and is provided under the 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• Earlier release tags (an older version or revision in the same pattern) are superseded.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 re-graded, and fixes appear only in newer releases: move to the current release. For a superseded release's build kit, ask support.

• Release tags never move, so pulling the same tag again never changes the image. To be offered each new release automatically (a new revision r<N+1>, or a new upstream version), use the ReadyStack Renovate preset: https://readystack.dev/updates.html⁠

• 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/airflow:3.3.2-CE-ubuntu24.04-r5

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

This release is signed; verify it with cosign verify --key https://readystack.dev/keys/cosign.pub readystack/airflow:3.3.2-CE-ubuntu24.04-r5 (the signature is recorded in the public Sigstore transparency log). Support: [email protected]⁠, as set out in the ReadyStack Agreement⁠.

⁠Deployment

Single container running airflow standalone, which supervises the API server, scheduler, DAG processor and triggerer in one foreground process against a self-contained SQLite metadata database. Workflows are Python files placed in /opt/airflow/dags.

docker run -d --name airflow -p 8080:8080 -v airflow-data:/opt/airflow readystack/airflow:3.3.2-CE-ubuntu24.04-r5

⁠The full ReadyStack Hermetic Build Kit

The complete --network=none build kit for this image — plus admin/DB/API handbooks, the build's validation records, and its build provenance records — is at readystack.dev/buy.html⁠. A clean-room rebuild from this release's archive on an egress-blocked host reproduced its linux/amd64 digest sha256:b411b52e4e7e0ecb4e5912aa466778e923c79257ad31af1b641d90b9a81b59e2 on 2026-10-28.
