# RustFS Helm Mode
|
||
|
||
RustFS helm chart supports **standalone** and **distributed** mode.
|
||
|
||
- **Standalone mode**: one pod with one PVC (single node, single disk).
|
||
- **Distributed mode** (**default**): multiple pods with multiple PVCs (multiple nodes, multiple disks).
|
||
|
||
## Distributed topology
|
||
|
||
The distributed topology is defined by two parameters:
|
||
|
||
- `replicaCount` — number of pods (nodes) in the StatefulSet.
|
||
- `drivesPerNode` — number of data PVCs mounted on each pod.
|
||
|
||
Total drives in the cluster = `replicaCount * drivesPerNode`.
|
||
|
||
When `drivesPerNode` is left unset, the chart automatically infers a
|
||
backward-compatible value from each pool's replica count (with pools
|
||
disabled there is a single pool driven by the top-level `replicaCount`):
|
||
|
||
| `replicaCount` | Inferred `drivesPerNode` | Legacy equivalent |
|
||
|----------------|--------------------------|-------------------|
|
||
| 4 | 4 | old default 4×4 |
|
||
| anything else | 1 | old 16×1, etc. |
|
||
|
||
You can override the inference by setting `drivesPerNode` explicitly, e.g.
|
||
`--set drivesPerNode=2` for an 8×2 cluster.
|
||
|
||
**IMPORTANT**: Kubernetes does **not** allow changes to
|
||
`volumeClaimTemplates` in an existing StatefulSet. If you want to change
|
||
`drivesPerNode` after installation you must delete the StatefulSet
|
||
(with `--cascade=orphan` to keep pods and PVCs) and recreate it, or perform a
|
||
full reinstall.
|
||
|
||
---
|
||
|
||
## Upgrade notes
|
||
|
||
Upgrading from chart versions that did **not** have `drivesPerNode` is safe
|
||
without manual intervention:
|
||
|
||
- Existing 4×4 deployments (default `replicaCount=4`) continue to receive 4
|
||
drives per node because the chart infers `drivesPerNode=4`.
|
||
- Existing 16×1 deployments (`replicaCount=16`) continue to receive 1 drive
|
||
per node because the chart infers `drivesPerNode=1`.
|
||
|
||
If you previously set `replicaCount=16` and now want a different topology,
|
||
set both `replicaCount` and `drivesPerNode` explicitly.

|
||
**NOTE**:
|
||
|
||
The chart pulls the rustfs image from Docker Hub by default. For private registries, provide either:
|
||
|
||
- **Existing secrets**: Set `imagePullSecrets` with an array of secret names
|
||
```yaml
|
||
imagePullSecrets:
|
||
- name: my-existing-secret
|
||
```
|
||
|
||
- **Auto-generated secret**: Enable `imageRegistryCredentials.enabled: true` and specify credentials plus your image details
|
||
```yaml
|
||
imageRegistryCredentials:
|
||
enabled: true
|
||
registry: myregistry.com
|
||
username: myuser
|
||
password: mypass
|
||
email: user@example.com
|
||
```
|
||
|
||
Both approaches support pulling from private registries seamlessly and you can also combine them.
|
||
|
||
- The chart default pull rustfs image from dockerhub, if your rustfs image stores in private registry, you can use either existing image Pull secrets with parameter `imagePullSecrets` or create one setting `imageRegistryCredentials.enabled` to `true`,and then specify the `imageRegistryCredentials.registry/username/password/email` as well as `image.rustfs.repository`,`image.rustfs.tag` to pull rustfs image from your private registry.
|
||
|
||
- The default storageclass is [`local-path`](https://github.com/rancher/local-path-provisioner),if you want to specify your own storageclass, try to set parameter `storageclass.name`.
|
||
|
||
- The default size for data and logs dir is **256Mi** which must satisfy the production usage,you should specify `storageclass.dataStorageSize` and `storageclass.logStorageSize` to change the size, for example, 1Ti for data and 1Gi for logs.
|
||
|
||
# Server pools (capacity expansion)
|
||
|
||
In distributed mode the chart can run multiple **server pools** — independent
|
||
StatefulSets whose drives together form one cluster, the same expansion model
|
||
the RustFS server already supports via space-separated `RUSTFS_VOLUMES`
|
||
expressions (`rc admin pool ls` / `expand` / `rebalance` / `decommission`).
|
||
|
||
With `pools.enabled=false` (default) the chart behaves exactly as before:
|
||
one StatefulSet driven by the top-level `replicaCount`/`storageclass`.
|
||
|
||
To expand an existing deployment, enable pools and describe the current
|
||
layout as pool 0 plus your new capacity:
|
||
|
||
```yaml
|
||
pools:
|
||
enabled: true
|
||
list:
|
||
- {} # pool 0: inherits top-level values and keeps the
|
||
# existing StatefulSet/pod/PVC names and data
|
||
- replicaCount: 4 # pool 1: new capacity
|
||
storageclass:
|
||
dataStorageSize: 10Gi
|
||
```
|
||
|
||
Each entry may set `replicaCount` (>= 2) and/or a `storageclass` block;
|
||
omitted fields inherit the top-level values. Additional pools render as
|
||
`<fullname>-pool<N>` StatefulSets; all pools share the headless service,
|
||
the main service, the configuration and the credentials.
|
||
|
||
Notes:
|
||
|
||
* **Pools are append-only.** The list index determines the StatefulSet name —
|
||
never remove or reorder entries. Retire a pool with
|
||
`rc admin decommission` before removing it from the list.
|
||
* During the expansion rollout, pods restart until every pod of every pool is
|
||
resolvable — the server refuses to start with unresolvable peers, so expect
|
||
a few crash/restart cycles before the cluster converges. This is harmless.
|
||
* After the cluster converges, run `rc admin rebalance start <alias>` to
|
||
spread existing objects across the new pool.
|
||
* Pod anti-affinity in pool mode is scoped per pool and **preferred**
|
||
(soft), not required: two pools can share nodes, and each pool's own pods
|
||
spread across distinct nodes when capacity allows. Soft affinity is
|
||
load-bearing for in-place expansion — with required rules, the
|
||
not-yet-rolled pods of the existing pool block the new pool's pods from
|
||
their nodes while the rolled pods crash on the unresolvable (Pending)
|
||
peers, deadlocking the rollout on any cluster with fewer nodes than the
|
||
total pod count. Single-pool deployments (`pools.enabled=false`) keep the
|
||
chart's existing required anti-affinity unchanged.
|
||
* The PodDisruptionBudget spans all pools: with the default
|
||
`pdb.maxUnavailable: 1`, at most one pod of the whole cluster may be
|
||
evicted at a time. This is deliberately conservative — quorum safety
|
||
matters across the union of all pools.

# Installation
|
||
|
||
## Requirement
|
||
|
||
* Helm V3
|
||
* RustFS >= 1.0.0-alpha.69
|
||
|
||
Due to the traefik and ingress has different session sticky/affinity annotations, and rustfs support both those two controller, you should specify parameter `ingress.className` to select the right one which suits for you.
|
||
|
||
## Installation with traefik controller
|
||
|
||
If your ingress class is `traefik`, running the command:
|
||
|
||
```
|
||
helm install rustfs -n rustfs --create-namespace ./ --set ingress.className="traefik"
|
||
```
|
||
|
||
## Installation with nginx controller
|
||
|
||
If your ingress class is `nginx`, running the command:
|
||
|
||
```
|
||
helm install rustfs -n rustfs --create-namespace ./ --set ingress.className="nginx"
|
||
```
|
||
|
||
# Installation check and rustfs login
|
||
|
||
Check the pod status
|
||
|
||
```
|
||
kubectl -n rustfs get pods -w
|
||
NAME READY STATUS RESTARTS AGE
|
||
rustfs-0 1/1 Running 0 2m27s
|
||
rustfs-1 1/1 Running 0 2m27s
|
||
rustfs-2 1/1 Running 0 2m27s
|
||
rustfs-3 1/1 Running 0 2m27s
|
||
```
|
||
|
||
Check the ingress status
|
||
|
||
```
|
||
kubectl -n rustfs get ing
|
||
NAME CLASS HOSTS ADDRESS PORTS AGE
|
||
rustfs nginx example.rustfs.com 10.43.237.152 80, 443 29m
|
||
```
|
||
|
||
Access the rustfs cluster via `https://example.rustfs.com` with the default username and password `rustfsadmin`.
|
||
|
||
> Replace the `example.rustfs.com` with your own domain as well as the certificates.
|
||
|
||
# TLS configuration
|
||
|
||
By default, tls is not enabled. If you want to enable tls(recommendated),you can follow below steps:
|
||
|
||
* Step 1: Certification generation
|
||
|
||
You can request cert and key from CA or use the self-signed cert(**not recommendated on prod**), and put those two files(eg, `tls.crt` and `tls.key`) under some directory on server, for example `tls` directory.
|
||
|
||
* Step 2: Certification specifying
|
||
|
||
You should use `--set-file` parameter when running `helm install` command, for example, running the below command can enable ingress tls and generate tls secret:
|
||
|
||
```
|
||
helm install rustfs rustfs/rustfs -n rustfs --set tls.enabled=true,--set-file tls.crt=./tls.crt,--set-file tls.key=./tls.key
|
||
```
|
||
|
||
# Gateway API support (alpha)
|
||
|
||
Due to [ingress nginx retirement](https://kubernetes.io/blog/2025/11/11/ingress-nginx-retirement/) in March 2026, so RustFS adds support for [gateway api](https://gateway-api.sigs.k8s.io/). Currently, RustFS only supports traefik as gateway class, more and more gateway class support will be added in the future after those classes are tested. If you want to enable gateway api, specify `gatewayApi.enabled` to `true` while specify `ingress.enabled` to `false`. After installation, you can find the `Gateway` and `HttpRoute` resources,
|
||
|
||
```
|
||
$ kubectl -n rustfs get gateway
|
||
NAME CLASS ADDRESS PROGRAMMED AGE
|
||
rustfs-gateway traefik True 169m
|
||
|
||
$ kubectl -n rustfs get httproute
|
||
NAME HOSTNAMES AGE
|
||
rustfs-route ["example.rustfs.com"] 172m
|
||
```
|
||
|
||
Then, via RustFS instance via `https://example.rustfs.com` or `http://example.rustfs.com`.
|
||
|
||
# Uninstall
|
||
|
||
Uninstalling the rustfs installation with command,
|
||
|
||
```
|
||
helm uninstall rustfs -n rustfs
|
||
```
|
