Replace MinIO with RustFS across Iceberg repos

[kevinjqliu]

Feature Request / Improvement

Why we moved to Quay: Docker Hub stopped serving minio/minio and minio/mc, which broke CI. As a stopgap we switched to quay.io/minio/* (#18071, apache/iceberg-rust#3220).

Why we need to move again: quay.io/minio/minio no longer allows anonymous pulls, so CI is breaking again. On top of that, MinIO Community Edition stopped publishing images in October 2025 and its repo was archived in April 2026, so even working images are frozen builds with no security fixes (see #14638). PyIceberg has already switched to RustFS (apache/iceberg-python#3928), and Polaris uses it too.

Proposal: Replace MinIO with RustFS everywhere. Name the service/container something generic like object-store rather than rustfs, so the next swap is a one-line image change.

iceberg-cpp	✅ RustFS	rustfs/rustfs:1.0.0; RustFS release binary on macOS	ci/scripts/start_object_store.sh, aws_test.yml	apache/iceberg-cpp#962
terraform-provider-iceberg	✅ RustFS	rustfs/rustfs:1.0.0	dev/docker-compose.yml	apache/terraform-provider-iceberg#123, apache/terraform-provider-iceberg#125

Notes:

• iceberg: Testcontainers has no RustFS module; use GenericContainer.
• Bucket setup currently uses mc, so it needs a replacement.
• Virtual-host-style addressing needs RUSTFS_SERVER_DOMAINS (see PyIceberg).

RustFS 1.0.0 is out as a stable release. We should pin rustfs/rustfs:1.0.0 everywhere instead of the RCs.

1.0.0 also includes rustfs/rustfs#7051, so RUSTFS_SERVER_DOMAINS shouldn't need the :9000 port anymore.

Thanks for looking into this @kevinjqliu! I'm glad we're able to move off of MinIO. Looks like I was a little ahead of the game with the RC builds and I appreciate you getting us on 1.0!

Thanks for investigating @kevinjqliu! This proposal sounds good to me, linking also the mailing list thread: https://lists.apache.org/thread/wnt4ojcjsv1frfg1drxpz3gj0l91c5jl.

I think we should unblock integration tests for now given that's fairly no regret; we can defer the docs / quickstart / etc. changes:

• Build: Replace MinIO with RustFS in integration tests #18247
• ci: replace MinIO with RustFS in S3 tests iceberg-cpp#962
• ci: replace MinIO with RustFS in integration tests iceberg-go#2055
