⁠What you get

Signature, user and attestations below were measured on the published digest sha256:8218893901eca5056027fc35c261914e2390f27abd992e99cfa4e10f8c9cb6ec 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#minio⁠
• 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 sha256:8218893901eca5056027fc35c261914e2390f27abd992e99cfa4e10f8c9cb6ec; verify with cosign verify --key https://readystack.dev/keys/cosign.pub readystack/minio:RELEASE.2025-10-15T17-29-55Z-CE-ubuntu24.04-r6.
• Attestations — An SPDX SBOM and SLSA v1 build provenance are attached to this digest.
• Runs as a non-root user (minio).
• Built from source by ReadyStack; the web Console's compiled React frontend is the prebuilt bundle that ships inside the github.com/minio/console Go module (//go:embed build/*), vendored with the Go dependencies; it is not built here.

⁠Which tag should I pull?

This image follows the ReadyStack release-tag convention:

• The current release is RELEASE.2025-10-15T17-29-55Z-CE-ubuntu24.04-r6 — 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• Earlier release tags (an older version or revision in the same pattern) are superseded.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 For a superseded release's build kit, ask support.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/minio:RELEASE.2025-10-15T17-29-55Z-CE-ubuntu24.04-r6

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

This release is signed; verify it with cosign verify --key https://readystack.dev/keys/cosign.pub readystack/minio:RELEASE.2025-10-15T17-29-55Z-CE-ubuntu24.04-r6 (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 (CGO-free), foreground process. S3-compatible OBJECT STORAGE: objects + metadata persisted on the local filesystem under /data (internal state under /data/.minio.sys). NO relational/SQL database. Embeds and serves a web Console (an object browser) on port 9001. The image IS the complete running instance (no docker-compose, no Kubernetes, no external DB). The entrypoint, /usr/local/bin/readystack-entrypoint.sh, works out the root password MinIO will use (from MINIO_ROOT_PASSWORD, a MINIO_ROOT_PASSWORD_FILE secret or MINIO_CONFIG_ENV_FILE), exits 1 if it is unset, blank or minioadmin (and also on other unusable credential input, for example a root user or password that starts with "env", a *_FILE secret or MINIO_CONFIG_ENV_FILE naming a missing or unreadable file, or an empty *_FILE secret), and then runs minio with the default arguments server /data --address :9000 --console-address :9001, which arguments after the image name replace.

Secrets go in an env file that only you can read, not on the command line, and passwords that only set up the first start come out of it after setup. Create minio.env with install -m 600 /dev/null minio.env, then write these lines into it with an editor, with your own values (a value typed into a shell stays in its history). Docker reads each line as written: no quotes around a value, no spaces around =.

# The root credential (access key and secret key); both are needed at every start.
MINIO_ROOT_USER=YOUR_ACCESS_KEY
MINIO_ROOT_PASSWORD=YOUR_STRONG_SECRET

docker run -d --name minio -p 9000:9000 -p 9001:9001 --env-file ./minio.env -v minio-data:/data readystack/minio:RELEASE.2025-10-15T17-29-55Z-CE-ubuntu24.04-r6

minio is this command's own container name. MINIO_ROOT_USER and MINIO_ROOT_PASSWORD in minio.env are required at every start: without a root password, or with the password minioadmin, the container exits at once with a readystack: message. Boot is fast (about 2 seconds to a 200 on /minio/health/live, tested). Sign in to the Console at http://:9001 with the same access key and secret key, or drive the S3 API on :9000 with a sig-v4 client (curl --aws-sigv4 or an AWS SDK; mc is not in this image). Arguments after readystack/minio:RELEASE.2025-10-15T17-29-55Z-CE-ubuntu24.04-r6 replace the default server /data --address :9000 --console-address :9001. ReadyStack ships no Compose file for this image.

A clean-room rebuild from this release's archive on an egress-blocked host reproduced its linux/amd64 digest sha256:6b1016ff4cd94697889e396861e8bde9a828b5c10969771781b46d99b11c6d30 on 2026-10-27.
