RustFS Migration Map: MinIO to RustFS

One ordinary docker-compose.yml with MinIO gives 6 findings, and each one comes with the exact RustFS line that replaces it. The map uses 15 rules and covers docker-compose, Dockerfile, Helm values.yaml, Chart.yaml and Terraform .tf files.

Why now

The minio/minio GitHub repository was archived in April 2026 and says "THIS REPOSITORY IS NO LONGER MAINTAINED." The community edition is AGPLv3 and is distributed as source code only. The legacy pre-compiled binaries "will not receive updates." Commercial or proprietary use goes to MinIO AIStor licensing.

RustFS (rustfs/rustfs, Apache-2.0) is S3-compatible and uses the same ports, 9000 for S3 and 9001 for the console. Its configuration names are different, though. Swapping only the image tag leaves you with a container that ignores MINIO_ROOT_USER, health checks that probe a path that does not exist, and encrypted objects that RustFS cannot read.

What it finds (free, no key)

Open a file and run RustFS Map: Check this file. Every MinIO line is listed with its line number and the replacement:

The 15 rules also cover minio/mc, minio/operator, bitnami/minio, the charts.min.io Helm repository (replaced by https://charts.rustfs.com, chart rustfs 1.0.1), MINIO_ACCESS_KEY/MINIO_SECRET_KEY, MINIO_VOLUMES, MINIO_BROWSER, legacy dl.min.io downloads and the aminueza/minio Terraform provider.

Things the image swap does not tell you

• The RustFS container runs as UID/GID 10001:10001. Bind-mounted data, log and TLS directories must be writable by that user.
• MinIO on-disk compatibility is a preview feature (rio-v2) and is not in the default build. Copy objects through the S3 API (rclone or any S3 client) instead of remounting the MinIO data directory.
• The RustFS sample default credential rustfsadmin is public. Always set RUSTFS_ACCESS_KEY and RUSTFS_SECRET_KEY.

Every replacement line comes from the RustFS repository (README and docker-compose.yml) and from charts.rustfs.com. Each rule stores its source URL.

Yardstick

Staying on a supported MinIO build means AIStor, which MinIO prices by quote. RustFS costs nothing to run under Apache-2.0. This map shows the cost of moving: the exact lines to change.

Full version (licence key)

The free check covers one file, completely. The full version covers the whole workspace: a dated MinIO-to-RustFS migration plan that maps every item across all files to its replacement, plus a CI gate that fails a build when it adds new MinIO use. The team key adds the company exposure report: how many projects still pull MinIO, since when, and what each one needs. Full version
