* refactor(replication): split four oversized hot-path functions into focused helpers Pure-move decomposition of the four oversized functions flagged by the replication compatibility review (P1-18), unblocking migration milestone M2 which requires resyncer moves to stay mechanical: - resync_bucket (522 lines -> 61-line step sequence): leader lock, target resolution, walk/collector/worker spawning, and dispatch loop extracted into focused helpers; pure decision helpers (DTO builders, HEAD-result classification) separated from IO orchestration. - replicate_all (411 lines -> 113-line main body): initial target-info seeding, read/stat option builders, skip-path notes, target HEAD action resolution, and the multipart/single-put payload transport extracted as private free functions. - start_mrf_processor (306 lines -> 46-line spawn body): recovery guard, ledger load, per-entry replay (delete/object/metadata), and retained entry resolution extracted; retry bookkeeping semantics preserved exactly (inner continue-paths push inside helpers, outer Missed push stays in the loop). - apply_iam_item (255 lines -> match dispatch skeleton): one helper per IAM item type. No behavior change: log texts, error paths, event emissions, and metric counts are byte-identical; existing tests unchanged and green (238 ecstore replication/mrf/resync + 232 rustfs site-replication). * feat(replication): proxy GET/HEAD/Tagging for unreplicated objects to replication targets (#6172) * feat(replication): proxy GET/HEAD/Tagging for unreplicated objects to replication targets Implements the MinIO active-active read-proxy protocol (P1-5 of the replication compatibility review): when a GET/HEAD/GetObjectTagging/ PutObjectTagging/DeleteObjectTagging request fails locally with not-found and the bucket has replication targets, the request is proxied to the targets in rule order, mirroring bucket-replication.go proxyGetToReplicationTarget/proxyHeadToRepTarget/proxyTaggingToRepTarget. Protocol surface: - Anti-loop: inbound {x-rustfs-,x-minio-}source-proxy-request is parsed into ObjectOptions (proxy_request + proxy_header_set, matching MinIO ProxyRequest/ProxyHeaderSet); a request carrying the marker with ANY value is never re-proxied. Outbound client proxy calls send the marker as "true"; replication worker convergence HEADs send it as "false" so a peer's proxy layer cannot answer a convergence check by proxying back to the source (which would fake Completed without a PUT). - Target selection: new replication_proxy.rs get_proxy_targets — empty when the marker is set, versioning is suspended, or no replication config; otherwise filter_target_arns -> TargetClient lookup, skipping targets with proxying disabled. - TargetClient gains head_object_for_proxy/get_object (streaming) and the three tagging calls. Proxy calls never send the replication-check SSE-C exemption header; customer SSE-C keys are forwarded verbatim so the target performs real decryption. Conditional (If-*) headers are not forwarded (MinIO parity); Range and part_number are, with parts_count/tag_count/storage_class/expiration passed through. - Metrics: proxy counters now count only real client proxy traffic, MinIO-aligned (one total per proxied request, one failed when no target served it). The previous misattributed counters — replication worker HEAD/PUT (#2672) and local tagging operations (#2682) — are removed; ReplProxyMetric now maps the tagging counters instead of dropping them. e2e (fake_s3_target extended with tagging + header journaling): proxied GET body + outbound header contract (marker present, no replication-check, SSE-C passthrough), HEAD, anti-loop 404 with zero outbound requests, GetObjectTagging, and metric mapping unit tests. Rolling note: proxying only activates for buckets with replication targets; requests carrying the marker keep pre-upgrade behavior. Refs rustfs/backlog#1675 (P1-5) * fix(replication): fail SSE-C passthrough closed on targets that drop transport headers (#6178) SSE-C ciphertext passthrough replicates via X-Rustfs-Replication-* transport headers. A MinIO/generic-S3 target silently discards them, storing bare ciphertext with no decryption material — yet the PUT succeeded, so the object reported COMPLETED with a silently unreadable replica (backlog#1675 N2). Fail-closed design: - SsecPassthroughCapability {Unknown, Supported, Unsupported} cached in BucketTargetSys per target ARN with a recording timestamp. Entries reset whenever the target is rebuilt, edited, or removed (arn_remotes_map lifecycle) and expire after SSEC_PASSTHROUGH_CAPABILITY_TTL (10 minutes): an expired verdict in either direction is re-earned through the audit, so an Unsupported target recovers automatically after an upgrade (at most one wasted PUT+HEAD audit per bad target per TTL window) and a Supported verdict cannot outlive a backend swapped behind the same endpoint. - Replication worker (replicate_object and replicate_all): fresh Unsupported targets never receive the PUT — the attempt fails immediately into the normal MRF retry channel with a "run ?replication-check to re-probe" hint. Unknown or expired verdicts are audited: after the PUT the worker HEADs the replica back through the replication-check channel (source version id mapped through resolve_read_api_version_id, so null-version objects audit correctly) and requires SSE-C evidence (the echoed customer-algorithm header); missing evidence records Unsupported and fails the attempt. Convergence HEADs are audited the same way, so a broken ciphertext replica from an earlier attempt can never launder itself into COMPLETED via an ETag match. The gate/evidence policy is pure (replication_target_boundary, staleness folded in as an input) for the M2 worker migration. - replication-check grows an SsecPassthrough probe phase: a probe PUT carrying the live transport-header shape, HEAD-back for evidence, and a machine-readable Code BucketRemoteSsecPassthroughUnsupported on failure. The probe verdict is synced into the runtime capability cache. Unlike VersionFidelity, a failed SsecPassthrough phase does NOT fail the target overall — it is a capability limit, not a broken replication contract, and a plaintext-only deployment against such a target must not turn red. - fake_s3_target: default mode now models a RustFS target (stores the transport headers, echoes SSE-C evidence); the new drop_unlisted_replication_headers mode models MinIO. The journal records whether a request carried transport headers. Receiver-echo verification: the replication-check HEAD exemption only skips SSE-C key validation; the response has always built sse-customer-algorithm from stored metadata (rustfs/src/app/object_usecase.rs), so no receiver change was needed — pinned end to end by the replication-check e2e against a real RustFS target. Rolling-upgrade constraint: RustFS targets older than the replication-check HEAD exemption (#5898) answer the audit HEAD without SSE-C evidence (or fail it outright), so SSE-C replication to such targets reports FAILED. This is deliberate — FAILED-and-retryable beats a silently undecryptable replica — and self-heals: once the target is upgraded, the next TTL expiry (or a manual ?replication-check re-probe) re-audits and records Supported. Plaintext and managed-SSE replication are unaffected. The capability cache is per-node; each node audits independently. Known limitations: - The audit judges evidence from the echoed customer-algorithm header only. A hypothetical target that preserves that one header while dropping other transport headers (partial-drop) would pass the audit; no known target behaves this way — observed targets drop the whole unknown-header family. - A mixed-version target cluster can flap the verdict between audits routed to different target nodes until the rollout completes; the TTL bounds how long each stale verdict persists. New e2e (backlog#1675 C1 + N2, red-first): fail-closed against a header-dropping fake (FAILED + no second PUT via the capability cache, journal-asserted; red run showed the old COMPLETED), replication-check reports the SsecPassthrough phase Code while the target stays OK overall, SSE-C heal convergence after a real target outage, and SSE-C existing-object resync landing a REPLICA readable with the customer key. TTL expiry in both directions is pinned at the cache and gate seams. * refactor(replication): move resyncer pure decision logic into rustfs-replication (M2) (#6180) * refactor(replication): move resyncer pure decision logic into rustfs-replication (M2) Pure-move milestone M2 of the ECStore replication split (backlog#1675 P1-17): relocate the resyncer's IO-free decision helpers, with their unit tests, into the crates they already belong to by type ownership. No behavior change. Moved into crates/replication: - resync.rs: resync_status_duration - delete.rs: resync_existing_delete_replication_info, replicate_delete_outcome, target_delete_version_id, delete_marker_purge_version_id, delete_marker_purge_mrf_entry - object.rs: version_identity_drifted, is_replication_target_offline_error, SsecPassthroughCapability, SsecPassthroughGate, ssec_passthrough_gate, ssec_passthrough_evidence_present (param-demoted to the echoed customer-algorithm string; ECStore keeps the HeadObjectOutput adapter) - filemeta.rs: NULL_VERSION_ID wire literal (crate-owned copy per the filemeta-independence contract) ECStore rewiring (Rule #14: imports stay in *_boundary.rs): - resync/object-decision/target boundaries re-export the moved symbols; resyncer call sites are unchanged - bucket_target_sys keeps only the verdict cache + TTL and re-exports the capability enum so existing consumer paths keep compiling Not moved (signatures carry ECStore or aws-sdk types): verify_resync_head_result, resync_target_error_detail, the SdkError classifiers, the replicate_all_* option/info builders, and the env-coupled bounded_resync_max_jobs admission clamp. README milestone table updated. * chore(replication): retire the datatypes.rs relay early README sanctions retiring datatypes.rs ahead of M4. The module was a pure relay (resync boundary -> datatypes -> mod.rs facade) with no external consumer importing it directly, so the facade now re-exports ResyncStatusType from replication_resync_boundary and the relay file is deleted. Consumers stay behind the ECStore facade, keeping Migration Rule #15 intact — the original retirement wording ("consumers import through rustfs-replication directly") conflicted with that rule and is corrected in the README. * chore(arch): extend migration guards to the M2-moved decision contracts The adversarial review of the M2 move found the per-symbol ratchet in check_architecture_migration_rules.sh was not extended for the moved symbols, leaving them free to be redefined in ECStore or imported past their boundary without CI noticing: - resync definition pin + boundary fences gain resync_status_duration; - the object-decision boundary fences gain the five delete-family helpers (delete_marker_purge_mrf_entry, delete_marker_purge_version_id, replicate_delete_outcome, resync_existing_delete_replication_info, target_delete_version_id); - the target-boundary fence gains the SSE-C gate family, the offline classifier, and version_identity_drifted; - a new definition pin rejects ECStore redefinitions of the M2-moved fns/enums (ssec_passthrough_evidence_present deliberately excluded: ECStore keeps a thin HeadObjectOutput adapter under that name). Mutation-verified: a probe fn ssec_passthrough_gate under crates/ecstore/src/bucket/replication trips the new pin. Also anchors the intentionally-duplicated NULL_VERSION_ID wire literal from the filemeta side and tightens the M2 README note on bounded_resync_max_jobs.

Quickstart
To get started with RustFS, follow these steps:
1. One-click Installation (Option 1)
curl -O https://rustfs.com/install_rustfs.sh && bash install_rustfs.sh
2. Docker Quick Start (Option 2)
The RustFS container runs as a non-root user rustfs (UID/GID 10001:10001). If you bind-mount host directories with Docker or Compose, every mounted path must be writable by that user, otherwise startup may fail with permission denied errors. This applies to data directories, log directories, and TLS certificate directories when RUSTFS_TLS_PATH is enabled.
# Create data and logs directories
mkdir -p data logs
# Change the owner of these directories
chown -R 10001:10001 data logs
# Using latest version
docker run -d -p 9000:9000 -p 9001:9001 -v $(pwd)/data:/data -v $(pwd)/logs:/logs rustfs/rustfs:latest
# Using specific version
docker run -d -p 9000:9000 -p 9001:9001 -v $(pwd)/data:/data -v $(pwd)/logs:/logs rustfs/rustfs:1.0.0-rc.2
If you use podman instead of docker, you can install the RustFS with the below command
# Create data and logs directories
mkdir -p data logs
# Run the container (podman will automatically set the folders ownership)
podman run -d -p 9000:9000 -p 9001:9001 -v $(pwd)/data:/data:Z,U -v $(pwd)/logs:/logs:Z,U rustfs/rustfs:latest
If you enable TLS with a bind-mounted certificate directory, prepare that mount the same way:
mkdir -p certs
chown -R 10001:10001 certs
You can also use Docker Compose. Using the docker-compose-simple.yml file in the root directory:
docker compose -f docker-compose-simple.yml up -d
Before running Compose with host bind mounts:
- Ensure every mounted host path is writable by
10001:10001. - If you enable TLS, ensure the certificate mount for
/opt/tlsis also readable by10001:10001. - If matching host ownership is not practical, run the
rustfsservice withuser: "<host-uid>:<host-gid>"instead. docker-compose-simple.ymlincludes avolume-permission-helperservice for named volumes.docker-compose-simple.ymlrelies on you to prepare bind-mounted host paths in advance.
Similarly, you can run the command with podman
podman compose -f docker-compose-simple.yml up -d
Webhook notification quick start (Docker):
docker run -d --name rustfs -p 9000:9000 \
-e RUSTFS_NOTIFY_ENABLE=true \
-e RUSTFS_NOTIFY_WEBHOOK_ENABLE_PRIMARY=on \
-e RUSTFS_NOTIFY_WEBHOOK_ENDPOINT_PRIMARY=http://<host-ip>:3020/webhook \
-e RUSTFS_NOTIFY_WEBHOOK_QUEUE_DIR_PRIMARY=/tmp/rustfs-events \
-e RUSTFS_OUTBOUND_ALLOW_ORIGINS=http://<host-ip>:3020 \
rustfs/rustfs:latest
Notes:
RUSTFS_NOTIFY_ENABLE=trueenables the global notify module switch.- For ARN
arn:rustfs:sqs::primary:webhook, use instance-scoped env vars with_PRIMARY. - If queue dir is omitted, default is
/opt/rustfs/events; ensure it is writable by the container runtime user. RUSTFS_NOTIFY_WEBHOOK_SKIP_TLS_VERIFY_PRIMARYdefaults tofalse; enabling it skips webhook TLS certificate verification, allows MITM attacks, and emits a startup warning. PreferRUSTFS_NOTIFY_WEBHOOK_CLIENT_CA_PRIMARYfor private CAs.- Since
1.0.0-beta.11, webhook endpoints on private or container networks (Docker Compose service names,host.docker.internal, RFC 1918 addresses) are blocked unless their exactscheme://host:portorigin is listed inRUSTFS_OUTBOUND_ALLOW_ORIGINS(the origin only, without the path). See Outbound Connection Policy.
NOTE: We recommend reviewing the docker-compose.yml file before running. It defines several services including Grafana, Prometheus, and Jaeger, which are helpful for RustFS observability. If you wish to start Redis or Nginx containers, you can specify the corresponding profiles.
3. Build from Source (Option 3) - Advanced Users
For developers who want to build RustFS Docker images from source with multi-architecture support:
# Build multi-architecture images locally
./docker-buildx.sh --build-arg RELEASE=latest
# Build and push to registry
./docker-buildx.sh --push
# Build specific version
./docker-buildx.sh --release v1.0.0 --push
# Build for custom registry
./docker-buildx.sh --registry your-registry.com --namespace yourname --push
The docker-buildx.sh script supports:
- Multi-architecture builds:
linux/amd64,linux/arm64 - Automatic version detection: Uses git tags or commit hashes
- Registry flexibility: Supports Docker Hub, GitHub Container Registry, etc.
- Build optimization: Includes caching and parallel builds
You can also use Make targets for convenience:
make docker-buildx # Build locally
make docker-buildx-push # Build and push
make docker-buildx-version VERSION=v1.0.0 # Build specific version
make help-docker # Show all Docker-related commands
Heads-up (macOS cross-compilation): macOS keeps the default
ulimit -nat 256, socargo zigbuildor./build-rustfs.sh --platform ...may fail withProcessFdQuotaExceededwhen targeting Linux. The build script attempts to raise the limit automatically, but if you still see the warning, runulimit -n 4096(or higher) in your shell before building.
4. Build with Helm Chart (Option 4) - Cloud Native
Follow the instructions in the Helm Chart README to install RustFS on a Kubernetes cluster.
For scanner pacing, cycle budgets, bitrot cadence, lifecycle transition status,
and single-node single-disk idle CPU tuning, see
Scanner Runtime Controls. For
repeatable scanner-pressure validation, see
Scanner Benchmark Runbook. For
drive timeout knobs on slow storage — including the walk stall budget that
governs ListObjects on large prefixes — see
Drive Timeout Tuning.
5. Nix Flake (Option 5)
If you have Nix with flakes enabled:
# Run directly without installing
nix run github:rustfs/rustfs
# Build the binary
nix build github:rustfs/rustfs
./result/bin/rustfs --help
# Or from a local checkout
nix build
nix run
6. X-CMD (Option 6)
If you are an x-cmd user:
# Run directly without installing
x rustfs
# Download the binary and install it to the global environment
x env use rustfs
rustfs --help
Accessing RustFS
- Access the Console: Open your web browser and navigate to
http://localhost:9001to access the RustFS console.- Default credentials:
rustfsadmin/rustfsadmin
- Default credentials:
- Create a Bucket: Use the console to create a new bucket for your objects.
- Upload Objects: You can upload files directly through the console or use S3-compatible APIs/clients to interact with your RustFS instance.
NOTE: To access the RustFS instance via https, please refer to the TLS Configuration Docs.
OIDC Roles Claim (Microsoft Entra ID)
RustFS supports mapping an OIDC claim containing role values into the existing
authorization pipeline. The roles_claim setting is optional: when unset or
empty, only the groups claim contributes to authorization (same as older
RustFS releases). For Microsoft Entra ID app roles, set roles_claim=roles so
both console admin checks and bucket IAM policies can evaluate those roles.
Example environment configuration (opt-in roles claim):
RUSTFS_IDENTITY_OPENID_ENABLE=on
RUSTFS_IDENTITY_OPENID_CONFIG_URL="https://login.microsoftonline.com/<tenant-id>/v2.0/.well-known/openid-configuration"
RUSTFS_IDENTITY_OPENID_CLIENT_ID="<client-id>"
RUSTFS_IDENTITY_OPENID_CLIENT_SECRET="<client-secret>"
RUSTFS_IDENTITY_OPENID_SCOPES="openid,profile,email"
RUSTFS_IDENTITY_OPENID_GROUPS_CLAIM="groups"
RUSTFS_IDENTITY_OPENID_ROLES_CLAIM="roles"
Policy condition example (evaluate app roles directly with jwt:roles; when
roles_claim is configured, RustFS also merges those values into jwt:groups
for backward compatibility with older policies):
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": ["admin:*"],
"Resource": ["arn:aws:s3:::*"],
"Condition": {
"ForAnyValue:StringEquals": {
"jwt:roles": ["RustFS.ConsoleAdmin"]
}
}
}
]
}
