⁠What you get

Signature, user and attestations below were measured on the published digest sha256:ced8888be99cd55db0efe6913a5ea8b0face53310fa0b58fbd87671798d7b0a1 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#portainer⁠
• 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:ced8888be99cd55db0efe6913a5ea8b0face53310fa0b58fbd87671798d7b0a1; verify with cosign verify --key https://readystack.dev/keys/cosign.pub readystack/portainer:2.45.3-CE-ubuntu24.04-r1.
• Attestations — An SPDX SBOM and SLSA v1 build provenance are attached to this digest.
• Runs as a non-root user (portainer).
• Built from source by ReadyStack.

⁠Which tag should I pull?

This image follows the ReadyStack release-tag convention:

• The current release is 2.45.3-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• Earlier release tags (an older version or revision in the same pattern) are superseded.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 For a superseded release's build kit, ask support.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/portainer:2.45.3-CE-ubuntu24.04-r1

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

This release is signed; verify it with cosign verify --key https://readystack.dev/keys/cosign.pub readystack/portainer:2.45.3-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, one static CGO-free Go binary (portainer) that serves a web UI + a REST API + an Edge reverse-tunnel server, all in one foreground process. Portainer is a container-management GUI for Docker / Docker Swarm / Kubernetes. ALL state - users, environments, stacks, settings, edge configs - lives in an EMBEDDED bbolt key-value database at /data/portainer.db that the server creates + migrates itself; NO external/relational DB, NO docker-compose, NO sidecar. The on-disk web frontend (dist/public) is served from /opt/portainer/public. The image IS the complete running instance.

docker run -d --name portainer -p 9000:9000 -p 9443:9443 -v portainer-data:/data -v /var/run/docker.sock:/var/run/docker.sock --group-add $(stat -c %g /var/run/docker.sock) readystack/portainer:2.45.3-CE-ubuntu24.04-r1

--group-add gives Portainer, which runs as the non-root user portainer (uid 999), the group that owns the host's Docker socket; with the socket mount alone it gets permission denied and cannot add the local environment. Leave out both the socket mount and --group-add if this Portainer should not manage the host it runs on. Add -p 8000:8000 only if remote Edge Agents must reach this instance.

⁠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:a2cbe2d511c57174efe65263c59e63f50b081168921f328977e8665e8b3c9e34 on 2026-10-27.
