* fix(scanner): treat replication status writebacks as status-class hits A replication status writeback (persist_replication_state_if_current in Update mode, including the heals the scanner queues during its own walk) marked the bucket dirty on the namespace path: it advanced the dirty-usage generation, woke the scanner, reached the durable dirty journal and entered the activity snapshot. Any replicated bucket therefore made every scanner cycle Superseded, the authoritative usage baseline was never certified and usage freshness stayed stale for as long as replication ran (#8375). The writeback is now status class: record_status_class_mutation records only the process-local producer coverage bit and nothing else. There is no rescan queue for it, because a deployment with an active replication rule already walks every bucket on every cycle (ScannerMaintenanceFeatures::needs_regular_cycle) and that walk refreshes replication_stats. The routing lives in a named, unit-tested function in rustfs/src/storage/storage_api.rs; tier-expiration cleanup removes data and stays on the namespace path. No persisted format, protocol, admin API or configuration changes. This is phase 1 of docs/architecture/scanner-per-bucket-convergence.md, which this change adds together with its index entry. Refs #8375, #8494, rustfs/backlog#2816. * fix(scanner): refresh replication statistics during maintenance Refresh compacted prefixes and completed bucket caches during replication maintenance. Bind set execution reuse to the observed replication statistics so a same-cycle retry cannot restore older counters. Co-Authored-By: heihutu <heihutu@gmail.com> Co-Authored-By: zhi22915 <qiuzgang@gmail.com> * test(scanner): avoid expanding the legacy S3 DTO surface Decode the existing replication configuration type from a JSON fixture instead of adding direct S3 DTO references to a new file. Preserve the compacted-prefix and same-cycle assertions and the footprint ratchet. Co-Authored-By: heihutu <heihutu@gmail.com> Co-Authored-By: zhi22915 <qiuzgang@gmail.com> * perf(scanner): keep raw enumeration bookkeeping linear per entry The page writer inserted into its building page with a push-and-sort on every entry and committed each page through a clone. Insert in sorted position and move the committed page into the index instead. Add a regression test that records 20,000 entries in one prefix and pins the cost to one hash per entry and well under a second, so the quadratic re-normalization removed by #8114 (rustfs#8113) cannot return once pacing builds on this walker. * feat(scanner): decouple bucket walkers from disk count Add the scanner key walkers_per_disk (RUSTFS_SCANNER_WALKERS_PER_DISK, 1 through 16, default 1). Each local coordinator disk of a set spawns that many bucket walkers; remote disks keep one. The walker count is what max_concurrent_disk_scans caps and the disk count stays the floor. The walkers of one disk share its scanner admission through LocalDiskAdmissionShare: the first walker to start a bucket takes the per-disk permit and the last to finish releases it, so a peer's remote request still sees one scan session per physical disk. Without the share the second walker was rejected as busy and retired. The disk_concurrency_budget log line reports walkers_per_disk, walkers and the reason for the effective limit. The default stays 1 because no local disk reports rotational media today; the design keeps a higher flash default as the intent. * docs(scanner): document walkers_per_disk in the Helm chart and configuration manuals RUSTFS_SCANNER_WALKERS_PER_DISK was only described in the scanner runtime controls table. Add it to the Helm chart (values, configmap rendering, README table, template test), the configuration crate's environment reference with operator guidance, and a short section in the operations manual on when to raise it and how to confirm it took effect. --------- Co-authored-by: Hauser <housemecn@gmail.com> Co-authored-by: heihutu <heihutu@gmail.com> Co-authored-by: zhi22915 <qiuzgang@gmail.com>

Quickstart
Important
Pool expansion notice:
- A single-node single-drive (SNSD) deployment is supported only as a standalone local path. It cannot expand in place or be added as a Pool. To move to a multi-drive topology, create a new deployment and migrate data through S3.
- Keep an existing multi-drive Pool's endpoints and Erasure Set width unchanged; expand by appending a new Pool. With ellipsis-based expansion, every Pool argument must contain an ellipsis expression and expand to at least two drive endpoints.
- Single-node multi-drive Pools and multi-node Pools with one drive per node are allowed, subject to valid Erasure Set geometry and EC settings; acceptance does not guarantee host-failure tolerance.
These topology rules follow MinIO, but automatic parity selection differs between the projects. See the Pool layout compatibility and regression tests before expanding a deployment.
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:1.0.1
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, the official image maps
/opt/rustfs/eventsinto the persistent/datavolume so it is writable by the runtime user and pending events survive container recreation. Overridequeue_dirwhen using another deployment layout. 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 a single-platform image locally
./docker-buildx.sh -p linux/amd64
# Build and push to registry
./docker-buildx.sh --push
# Build specific version
./docker-buildx.sh --release 1.0.1 --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=1.0.1 # 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
The flake also exports a NixOS module and the RustFS rc client. Add the
module to your system and provide credentials through runtime files (for
example, sops-nix or agenix) so secrets are never stored in the Nix store:
imports = [ inputs.rustfs.nixosModules.rustfs ];
services.rustfs = {
enable = true;
accessKeyFile = "/run/secrets/rustfs-access-key";
secretKeyFile = "/run/secrets/rustfs-secret-key";
volumes = [ "/var/lib/rustfs" ];
};
Install the S3-compatible client with
nix profile install github:rustfs/rustfs#rustfs-client (the executable is named
rc), or use inputs.rustfs.packages.${pkgs.system}.rustfs-client in a system
configuration.
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"]
}
}
}
]
}
