* fix(object-data-cache): make cache metrics one-increment-per-GET
Rework the object data cache observability so each counter carries one
clear meaning, and drop dead per-entry state.
ODC-17 (backlog#1122): split requests_total, which was incremented by
both plan_get and lookup_body, into plan_total{decision,reason,size_class}
(emitted only by plan_get) and lookup_total{result,size_class} (emitted
only by lookup_body). Each is now incremented exactly once per GET per
layer; help text states this.
ODC-18 (backlog#1123): add a JoinedInflightFill result (label
joined_inflight) so a singleflight waiter is no longer counted as an
insert. record_fill_result now always counts the outcome but records
fill bytes only when non-zero and the duration histogram only when
present, so joined_inflight / skipped_by_mode / skipped_size_mismatch
no longer inflate fill_bytes_total or add non-fill duration samples.
The waiter->JoinedInflightFill mapping lives in MokaBackend (owned by a
concurrent branch); cache.rs handles the variant already.
ODC-29 (backlog#1134): stop refreshing the cache-state gauge on every
lookup, and debounce it on fill/invalidate to at most once per second
via an AtomicU64 millis timestamp, since moka's entry_count is a
settling approximation.
ODC-36 (backlog#1141): give invalidations_total an outcome label
(removed|noop) and skip the gauge refresh on the no-op path. Extend
ObjectDataCacheInvalidationResult with Removed{keys}/NoOp (Success kept
as a transitional variant until MokaBackend reports the removal count);
NoopBackend now reports NoOp.
ODC-30 (backlog#1141): drop the dead content_length/etag/inserted_at
fields (and getters) from ObjectDataCacheEntry, which are redundant with
the moka key identity; the constructor keeps its arity so the
out-of-scope MokaBackend caller still compiles. Gate is_null_version
behind cfg(test).
Tests use a thread-local metrics recorder to avoid the global-singleton
flakiness. Fill-enabled test configs set min_free_memory_percent=0 so
the cgroup gate does not refuse fills in CI pods.

* fix(object-data-cache): move fill off GET path, bound & harden the fill
Implements five object-data-cache audit findings.
ODC-15 (backlog#1120): the GET response no longer blocks on cache fill.
The buffered/materialized body is already in hand, so the fill now runs
in a detached task and the response is built immediately. Singleflight is
made non-blocking: `try_acquire` returns Leader or Busy, and a non-leader
skips its own fill (SkippedSingleflightBusy) instead of waiting on another
request's leader. The inner fill spawn is KEPT: once the index key is
registered, the recheck/undo must complete even if the enclosing fill
future is aborted, so removing it would weaken the cancellation-safety
guarantee (ODC-13 test) and the invalidation-race undo.
ODC-11 (backlog#1116): enforce the fill-concurrency knobs. MokaBackend
now holds a Semaphore sized min(per_cpu * parallelism, max), acquired
after winning leadership and before the memory gate. On saturation it
rejects (try_acquire_owned) with SkippedFillConcurrency rather than
queueing, so the fill path never reintroduces GET-latency coupling.
ODC-14 (backlog#1119): the memory gate no longer does a blocking sysinfo
refresh under a mutex on the async fill path. A dedicated periodic
refresher (tokio interval + spawn_blocking) updates an atomic snapshot
every 5s; allows_fill is now lock-free. The min_free_memory_percent == 0
short-circuit still runs before any snapshot read. No runtime at
construction (sync unit tests) simply keeps the seed snapshot.
ODC-32 (backlog#1137): singleflight no longer emits metrics while holding
the map mutex. try_acquire/remove_entry capture the map length under the
guard, drop it, then emit the gauge/counter.
ODC-07 (backlog#1112): the materialize read is bounded via
take(capacity + 1) so an over-long stream cannot grow the buffer past the
in-memory GET threshold, and any length mismatch is now a hard error
matching the direct-memory GET path, instead of warn-and-serve.
cache.rs is owned by a concurrent branch; this commit only appends the
SkippedFillConcurrency and SkippedSingleflightBusy variants + label arms.

* fix(object-data-cache): report JoinedInflightFill and invalidation outcome
Reconciles the moka_backend half of two metrics-semantics findings after
merging fix/odc-metrics-semantics (which landed the cache.rs half).
ODC-18 (backlog#1123): the singleflight non-leader path now returns
JoinedInflightFill instead of counting as an insert, so N concurrent GETs
of one cold key record one insert, not N. This composes with the ODC-15
redesign: the non-leader does NOT wait for the leader (it already owns the
body and never re-serves from the fill result), so no blocking wait is
reintroduced. Drops the redundant local SkippedSingleflightBusy variant in
favor of the canonical JoinedInflightFill (mapped to no bytes / no duration
by the facade). SkippedFillConcurrency (ODC-11) is retained.
ODC-36 (backlog#1141): MokaBackend::invalidate_object now returns
Removed { keys } / NoOp instead of the transitional Success, so the facade
labels invalidations_total{outcome=removed|noop} and skips the cache-state
gauge refresh on the no-op path.
Tests: duplicate-fill test asserts JoinedInflightFill (bites when reverted
to Inserted); new no-op invalidation test; matching-identity test asserts
Removed { keys: 1 }.

* fix(object-data-cache): drop unused mut on materialize stream binding
The ODC-07 change moves `final_stream` into `AsyncReadExt::take`, so the
`build_get_object_body_with_cache` parameter is no longer mutated in place.
Co-Authored-By: heihutu <heihutu@gmail.com>
* refactor(object-data-cache): close the cross-branch coordination seams
Merging the metrics and hot-path branches left four transitional shims that
only existed because each side could not edit the other's files. With both
sides present they are dead weight, and two of them actively misreport.
- ObjectDataCacheEntry::new took content_length and etag only to keep the
caller in moka_backend.rs compiling, then discarded both. Drop them; the
entry is a Bytes wrapper and the caller now passes only the body.
- SkippedSingleflightClosed lost its only producer when the waiter model was
replaced by Leader/Busy election. Remove the variant.
- The fill-accounting match ended in a wildcard that charged fill_bytes and a
duration to every non-Inserted outcome, so a fill rejected by the memory
gate or the concurrency semaphore — which never touched the backend and
wrote nothing — still inflated fill_bytes_total. Enumerate every variant
explicitly: only outcomes that wrote the body report bytes and duration.
Exhaustiveness also forces a future variant to state its accounting rather
than inherit a wrong default.
- InvalidationResult::Success mapped a no-op to outcome=removed, the exact lie
backlog#1141 set out to fix, and its doc comment claimed MokaBackend still
returned it after that backend had been widened. It has no producer left.
Remove it, and tighten the app-layer test from "any successful variant" to
the real contract: the pre-mutation call reports Removed{keys:1}, the
post-delete call NoOp.

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.8
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 \
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.
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.
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"]
}
}
}
]
}
