The LoadBucketMetadata peer-notification handler loaded bucket metadata with the fabricating loader (ConfigNotFound -> BucketMetadata::new) and unconditionally cached the result. On a transient read-quorum dip during a reload notification, a peer cached an authoritative "no Object Lock" default for a lock-enabled bucket, disabling the batch-delete retention gate (object_lock_delete_check_required) on that node until the next refresh, and wiping its bucket-target/durability sync state. Production changes: - New BucketMetadataSys::reload_from_store (metadata_sys:: reload_bucket_metadata): the peer reload path uses the presence-aware loader and installs only metadata actually read from persisted storage. A load miss returns an error (surfaced to the notifying peer as success=false) and leaves the cache untouched; deletion still propagates only through the dedicated DeleteBucketMetadata notification. - The reload runs under the outer metadata-sys write guard, load included, mirroring update(): every other cache installer holds that lock, so a reload snapshot can never land after - and roll back - a newer concurrent install (the stale-load lost-update from the review), and the install-plus-registry-sync sequence stays atomic against concurrent removes and reloads (previously only the set call was write-guarded, with the load outside any lock). - The peer-visible miss error is a fixed string: the notifying peer substring-matches error text against network-failure needles (is_network_like_error), so interpolating a bucket name (e.g. a legal bucket literally named "unavailable") could mark a healthy peer offline. - get_config's lazy insert routes through set(), picking up the negative-cache invalidation. An earlier draft instead guarded set() with a per-config updated_at freshness comparison. Adversarial validation rejected it (three roles independently): update_config stamps with the handling node's wall clock, so within the skew the cluster already tolerates (+/-300s RPC auth window) a config rewritten with an earlier stamp - e.g. revoking a public-read policy through a second node, or any same-field rewrite after an NTP step-back - would be skipped by every peer forever, silently pinning the revoked permissive config with no re-convergence path (the 15-minute refresh also routed through the guard). Race staleness is second-scale while skew is minute-scale, so no tolerance bound can separate them; the write-guard serialization closes the same race without clocks and preserves the refresh loop's unconditional converge-to-disk property, which is the cluster's self-healing mechanism. Startup audit (BucketMetadataSys::init): concurrent_load's insert-if-vacant still installs a fabricated default when a transient miss hits at boot - indistinguishable from a legacy bucket without a metadata file at this layer - bounded by the next successful persisted load. Making the object-lock gate fail closed on such entries is filed as a follow-up, alongside the bare "unavailable" needle in is_network_like_error and the Swift cache-only metadata writes. Tests: - bucket::metadata_sys::tests:: peer_reload_never_caches_fabricated_defaults_as_authoritative: miss installs nothing / miss keeps the existing entry intact (asserting the dedicated non-persisted error) / persisted reload converges the cache over a stale entry. - node_service::tests:: test_load_bucket_metadata_failure_skips_scanner_maintenance: a failed reload reports failure and does not advance scanner maintenance activity (previously recorded even on a miss). - The handler success path stays uncovered at the RPC layer (needs an isolated global object layer, like the pre-existing ignored test); the composition is pinned at the sys level instead. Verification: - cargo fmt --check and cargo clippy --lib --tests clean on rustfs-ecstore and rustfs. - Targeted suites green; full cargo test -p rustfs-ecstore --lib: 3198/3200 with two parallelism-sensitive lock-test flakes from the known baseline (pass in isolation; a different pair flakes per run). - Adversarial validation (high-risk tier, all seven roles as independent parallel reviewers) run per AGENTS.md; all findings fixed or rebutted with evidence, three out-of-scope findings filed as follow-up tasks.

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-beta.11
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"]
}
}
}
]
}
