* fix(decommission): adopt target intents left by a killed leader
A decommission leader killed after persisting a target capacity intent and
before finalizing it left that intent in the exclusive pending slot of the
still-active reservation. The resumed routine derives the same reservation
identity, but every other mutation on that target was rejected as "another
mutation" until the interrupted object happened to be retried on the same
target, so the resumed decommission exhausted its retries and stalled.
At routine start, before any worker runs, the resumed routine now adopts the
reservation's pending intents: under the target fence (or the legacy pool
metadata fence) it moves each one into a mutation-scoped inflight marker that
keeps its identity and bytes. The interrupted mutation's retry settles the
marker through the existing commit, temporary-release and equivalent-target
paths, and an equivalent committed target now settles a mutation's own marker
when no pending intent remains. Adoption is pinned to the persisted
decommission start time and reservation identity, never runs mid-incarnation,
and a failure pauses the routine instead of marking the decommission failed.
* fix(decommission): keep adopted intents within budget and settle them once
Address the adversarial review of the leftover intent adoption.
- Merge an adopted intent into its mutation's staged marker by summing only
while the target's temporary-copy budget allows, never below the larger of
the two. A multipart completion moves its staged parts into the object, so
summing them could exceed the budget and pause every later routine start;
the adopted marker now exceeds the budget only where the completion's own
finalize would have. Reuse resolve and record_inflight for the move.
- Distinguish a temporary release that proved the exact committed target from
one that could not prove the target identity. When the committed mutation no
longer has a pending intent, release only the bytes the cleanup freed and
keep the adopted completion for the equivalent-target reconciliation.
- Let an equivalent target settle a mutation's own marker while another
mutation holds the pending slot, instead of failing on that unrelated intent.
- Cover real leader kills before and after the target commit at routine level
for both lock models, an injected adoption failure that pauses and then
completes, an adopted multipart completion surviving a background abort, and
a live legacy intent. Routine tests reuse the large-stack test helper.
* fix(decommission): pause instead of failing on target slot contention
The S00 leader-kill run with the null-version fix merged ended the resumed
decommission as failed. A re-run of a versioned key reconciled its delete
marker against an already charged target copy while another worker of the
same incarnation held the target's pending slot between a failed write and
its retry. The reconciliation rejected that unrelated intent, the entry
context wrapper flattened the error to a string the intent-conflict retry
could not recognize, and the bucket runner reported a sibling bucket's
OperationCanceled instead of the capacity block, so the routine marked the
decommission failed.
- An equivalent-target reconciliation, including the temporary checkpoint
variant, no longer depends on another mutation's pending intent: a target
holds one pending intent at a time, so this mutation has none to settle.
- The entry context keeps the typed cause, and the capacity-block and
intent-conflict classifiers also recognize the rendered message that an
error clone keeps.
- Concurrent bucket and listing failures keep the root cause over sibling
cancellations, so a capacity block pauses the routine.
* test(decommission): delete marker copy waits for a busy target gate
The Linux run of the S00 matrix showed the delete marker copy meeting a busy
target capacity gate without any leader kill. The copy already waits on that
gate like an ordinary object copy; pin it with an entry-level test that holds
the gate, checks the entry keeps waiting, and expects the key to migrate once
the gate is released. Share the versioned delete marker fixture with the
foreign pending slot test.
* fix(decommission): keep an adopted completion unless the target is absent
Close the remaining path where an adopted completion could lose its record
before being charged. A multipart cleanup that found a target it could not
prove as the exact owned copy still dropped the whole marker of a mutation
without a pending intent, after which the equivalent-target reconciliation
would treat the commit as already charged.
Any cleanup that did not prove the exact target absent now releases only the
bytes it freed when the mutation has no pending intent, and leaves the rest
for the reconciliation. This makes the three-state release unnecessary, so
the release proof goes back to the existing clear-pending flag.
* chore(ci): shrink the error format ratchet baseline for pools.rs
9eae47ce8 removed one Error::other(format!) call site from crates/ecstore/src/core/pools.rs, so the ratchet requires the baseline to drop from 178 to 177.
* fix(decommission): keep adopted completions in their own capacity marker
An adopted completion shared the mutation's staged marker, so whether
it survived a cleanup depended on the pool-wide free-space delta, and a
cleanup that freed little space left staged bytes behind and repeated
forever.
Record each adopted intent under a mutation id derived from the
interrupted mutation (decommission_adopted_intent_mutation_id) as a
separate temporaryMutations entry. A commit or an equivalent-target
reconciliation settles both markers, a temporary cleanup releases the
staged marker as before, and only a cleanup that proved the exact
target absent drops the adopted one. While the target holds only that
adopted completion, a cleanup keeps the delayed-release exemption of
the published pending intent it replaced. Older nodes see an ordinary
temporary mutation they never release, which only over-reserves.
Also log capacity_intents_adopted as soon as the adopted ledger is
durable, merge the root-cause helpers into decommission_root_cause,
drop the decommission_capacity_blocked: prefix fallback, and log the
already-charged equivalent-target branch at debug level.
Refs rustfs/backlog#2873, rustfs/backlog#2872
* fix(decommission): return uncommitted retries to their adopted target
A retry that had not committed yet went to the reserved target with the
most remaining allocation. When that was not the target holding the
mutation's adopted completion, the commit settled only its own target
and the adopted marker stayed inflight until the reservation was
released.
Prefer a reserved target that holds the mutation's adopted marker while
it still fits the object (decommission_reserved_target_choice).
Also cover the remaining settlement paths of the derived marker
(non-growing replacement, equivalent temporary reconciliation and its
discovery gate, scanner backlog retirement), repeated adoption of one
mutation and the zero-byte staging record in both lock models, drop two
conditions that always equal another one, and correct the adopted-id
doc comment about nodes without adoption.
Refs rustfs/backlog#2873, rustfs/backlog#2872
* fix(decommission): count a completion adopted twice only once
A mutation killed twice leaves an adopted completion and then a new
intent for the same object version. Adoption added the two, so an
11-byte object counted 22 inflight bytes and could trip the capacity
check once later commits shrank the budget. Both reserve the same
completion, so merge them by their maximum before adding staged parts;
a single adoption is unchanged.
Also assert in the three-pool sticky test that no entry failed, the
retry is charged on its adopted target and the source is cleaned, run
it for the legacy lock model too, stop saying operators rely on the
adoption log before rollback, and document that the selection fallback
cannot help an adopted completion.
Refs rustfs/backlog#2873, rustfs/backlog#2872
* fix(decommission): log where an adopted retry is placed
An e2e run could not show whether a resumed retry went back to the
target holding its adopted completion. Target selection now logs
adopted_target_reused when it does, and adopted_target_bypassed with
the adopted target pools when the object no longer fits there and the
adopted marker stays behind. Both carry the mutation id and the source
and target pools.

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:1.0.3
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 1.0.3 --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=1.0.3 # 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"]
}
}
}
]
}
