RustFS is a high-performance, distributed object storage system built in Rust—one of the most loved programming languages worldwide. RustFS combines the simplicity of MinIO with the memory safety and raw performance of Rust. It offers broad S3 API compatibility for supported features, is completely open-source, and is optimized for data lakes, AI, and big data workloads.

Unlike other storage systems, RustFS is released under the permissible Apache 2.0 license, avoiding the restrictions of AGPL. With Rust as its foundation, RustFS delivers superior speed and secure distributed features for next-generation object storage.

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/tls is also readable by 10001:10001.
• If matching host ownership is not practical, run the rustfs service with user: ":" instead.
• docker-compose-simple.yml includes a volume-permission-helper service for named volumes. docker-compose-simple.yml relies 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=true enables 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_PRIMARY defaults to false; enabling it skips webhook TLS certificate verification, allows MITM attacks, and emits a startup warning. Prefer RUSTFS_NOTIFY_WEBHOOK_CLIENT_CA_PRIMARY for 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 exact scheme://host:port origin is listed in
RUSTFS_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 -n at 256, so cargo zigbuild or ./build-rustfs.sh --platform ... may fail with ProcessFdQuotaExceeded when targeting Linux. The build script attempts to raise the limit automatically, but if you still see the warning, run ulimit -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

1. Access the Console: Open your web browser and navigate to http://localhost:9001 to access the RustFS console.

• Default credentials: rustfsadmin / rustfsadmin

1. Create a Bucket: Use the console to create a new bucket for your objects.
2. 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"]
        }
      }
    }
  ]
}
