⁠What you get

Signature, user and attestations below were measured on the published digest sha256:489418c715b4d5faf9f438e826fc78cb6f57e3fabea8ba0dfd894e9f575bdf25 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#argocd⁠
• 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 sha256:489418c715b4d5faf9f438e826fc78cb6f57e3fabea8ba0dfd894e9f575bdf25; verify with cosign verify --key https://readystack.dev/keys/cosign.pub readystack/argocd:v3.5.5-CE-ubuntu24.04-r1.
• Attestations — An SPDX SBOM and SLSA v1 build provenance are attached to this digest.
• Runs as a non-root user (999).
• Built from source by ReadyStack.

⁠Which tag should I pull?

This image follows the ReadyStack release-tag convention:

• The current release is v3.5.5-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• Earlier release tags (an older version or revision in the same pattern) are superseded.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 For a superseded release's build kit, ask support.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/argocd:v3.5.5-CE-ubuntu24.04-r1

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

This release is signed; verify it with cosign verify --key https://readystack.dev/keys/cosign.pub readystack/argocd:v3.5.5-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 self-contained container. The Argo CD components (argocd-server, argocd-repo-server, argocd-application-controller) and redis run INSIDE this one image under supervisord, next to an embedded k3s that serves as the Kubernetes API and datastore. There is no argocd-dex-server in this image (no dex process; /api/dex answers 404). This is NOT a Kubernetes deployment / Helm install / kubectl apply of the install manifests — the image IS the complete running instance. Argo CD can manage external clusters once you register them, but the control plane itself is this one container.

docker run -d --name argocd -p 8080:8080 readystack/argocd:v3.5.5-CE-ubuntu24.04-r1

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:a839c35b4f2f97e8cb783848232b6bf34e3373a3717c0397d028b0545d276248 on 2026-10-21.
