readystack/opensearch:3.9.0-CE-ubuntu24.04-r1

A cosign-signed build of github.com/opensearch-project/OpenSearch 3.9.0 (Apache-2.0 — the OSS fork of Elasticsearch), repackaged clean-room from upstream's prebuilt release artifact by ReadyStack⁠.

⁠What you get

Signature, user and attestations below were measured on the published digest sha256:15e1363f73d324ef2b58863f878969cf5a5d4c2458628b41e2eb0e9b7dd06f9d on 2026-10-21.

• Scan scores — we scan every image we publish every day (an SBOM made with syft, vulnerabilities matched with grype, scored with ce.rodeo's published rubric) and record each scan with how its score was derived. This release's first and latest scan: https://readystack.dev/products.html#opensearch⁠
• ReadyStack release check — passed at release on 2026-10-21: 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 sha256:15e1363f73d324ef2b58863f878969cf5a5d4c2458628b41e2eb0e9b7dd06f9d; verify with cosign verify --key https://readystack.dev/keys/cosign.pub readystack/opensearch:3.9.0-CE-ubuntu24.04-r1.
• Attestations — An SPDX SBOM and SLSA v1 build provenance are attached to this digest.
• Runs as a non-root user (opensearch).
• Repackaged from upstream's prebuilt release by ReadyStack (https://artifacts.opensearch.org/releases/bundle/opensearch/3.9.0/opensearch-3.9.0-linux-x64.tar.gz⁠, sha256 f52702238e4c…); this build compiles none of upstream's code.

⁠Which tag should I pull?

This image follows the ReadyStack release-tag convention:

• The current release is 3.9.0-CE-ubuntu24.04-r1 — 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• Earlier release tags (an older version or revision in the same pattern) are superseded.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 For a superseded release's build kit, ask support.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/opensearch:3.9.0-CE-ubuntu24.04-r1

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

This release is signed; verify it with cosign verify --key https://readystack.dev/keys/cosign.pub readystack/opensearch:3.9.0-CE-ubuntu24.04-r1 (the signature is recorded in the public Sigstore transparency log). Support: [email protected]⁠, as set out in the ReadyStack Agreement⁠.

⁠Deployment

Single container, JVM (system OpenJDK 21) search + analytics engine, foreground bin/opensearch. HTTP REST API on :9200, transport on :9300. Indices persist under /opt/opensearch/data. NO SQL DB, NO sidecar (single-node). This is the OpenSearch ENGINE only (OpenSearch Dashboards is a separate product). The lean CE image drops the bundled JDK (uses our dist-upgraded system OpenJDK 21) and the two heavy security/security-analytics plugins.

docker run -d --name opensearch -p 9200:9200 -p 9300:9300 -v opensearch-data:/opt/opensearch/data readystack/opensearch:3.9.0-CE-ubuntu24.04-r1

⁠The full ReadyStack Agent-ready Archive

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:c0bb67beaf99104eca1a47bce001eb8ddec1e472b5aa6cbd865b6f301cbe96d5 on 2026-10-21.
