⁠What you get

Signature, user and attestations below were measured on the published digest sha256:1548615f351e9ecbf137be6de6ff69e09945b50a0975e62ad3a041919d4ff33d on 2026-10-27.

• 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#loki⁠
• ReadyStack release check — passed at release on 2026-10-27: 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 sha256:1548615f351e9ecbf137be6de6ff69e09945b50a0975e62ad3a041919d4ff33d; verify with cosign verify --key https://readystack.dev/keys/cosign.pub readystack/loki:v3.7.9-CE-ubuntu24.04-r2.
• Attestations — An SPDX SBOM and SLSA v1 build provenance are attached to this digest.
• Runs as a non-root user (loki).
• Built from source by ReadyStack.

⁠Which tag should I pull?

This image follows the ReadyStack release-tag convention:

• The current release is v3.7.9-CE-ubuntu24.04-r2 — 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• Earlier release tags (an older version or revision in the same pattern) are superseded.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 For a superseded release's build kit, ask support.

• 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/loki:v3.7.9-CE-ubuntu24.04-r2

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

This release is signed; verify it with cosign verify --key https://readystack.dev/keys/cosign.pub readystack/loki:v3.7.9-CE-ubuntu24.04-r2 (the signature is recorded in the public Sigstore transparency log). Support: [email protected]⁠, as set out in the ReadyStack Agreement⁠.

⁠Deployment

Single container, single static Go binary running in single-binary monolithic mode (-target=all, all components in one process), foreground process. Log aggregation with the tsdb index + chunk object-store BOTH on the local filesystem under /loki; NO relational/SQL database, NO external object store, NO sidecar. The image IS the complete running instance.

docker run -d --name loki -p 127.0.0.1:3100:3100 -v loki-data:/loki readystack/loki:v3.7.9-CE-ubuntu24.04-r2

Starts a single Loki server (single-binary -target=all) with its data in the loki-data volume. Cold start to /ready (200, body 'ready') measured 14-17 seconds across three boots. Reach it at http://localhost:3100⁠ (published on the host's 127.0.0.1 only, because Loki has no authentication: anyone who reaches port 3100 can push and query; containers on the same Docker network can reach it regardless). Port 9095 (internal gRPC) is not published and does not need to be (tested); it still listens on all container interfaces, so containers on the same Docker network can reach it, unauthenticated like 3100. The archive ships no ReadyStack Compose file for this image (the docker-compose files under the upstream source tree are upstream's examples and run upstream's grafana/loki images).

⁠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:abe518fe1e67e85aeaa9c5d00bcbe49dc22a14f87d27b27de448f1d9041cf498 on 2026-10-27.
