# MinIO

> Deploy MinIO on Control Plane using the Template Catalog. Covers configuration, volumes, scaling, and distributed S3-compatible object storage with erasure coding.

## Overview

MinIO is a high-performance, S3-compatible object storage system. This template deploys a distributed MinIO cluster with erasure coding across multiple replicas for durability and fault tolerance, backed by persistent storage and an optional autoscaling volume set.

### What Gets Created

* **Stateful Workload** — A distributed MinIO cluster with a configurable number of replicas (minimum 4, must be even).
* **Volume Set** — Persistent storage per replica with optional autoscaling.
* **Secrets** — An opaque startup script secret that configures the distributed server list and handles node initialization, and a dictionary secret storing the admin username and password.
* **Identity & Policy** — An identity bound to the workload with `reveal` access to both secrets.

<Note>
  This template does not create a GVC. You must deploy it into an existing GVC.

## Configuration

The default `values.yaml` for this template:

```yaml theme={null}
image: minio/minio:RELEASE.2025-09-07T16-13-09Z

replicas: 6 # Must be at least 4 and an even number

admin: # MinIO admin credentials
  username: myuser
  password: mypassword123

resources: # Defaults are set for minimal production usage
  minCpu: 1
  minMemory: 2Gi
  maxCpu: 2
  maxMemory: 4Gi

volumeset:
  capacity: 10 # initial capacity in GiB (minimum is 10)
  autoscaling:
    enabled: false
    maxCapacity: 100 # Maximum capacity in GiB
    minFreePercentage: 10 # Trigger scaling when free space drops below this percentage
    scalingFactor: 1.2 # Multiply current capacity by this factor when scaling up

internalAccess:
  type: same-gvc # options: none, same-gvc, same-org, workload-list
  workloads: # Note: can only be used if type is same-gvc or workload-list
    #- //gvc/GVC_NAME/workload/WORKLOAD_NAME
```

### Credentials

* `admin.username` — MinIO admin username. **Change before deploying to production.**
* `admin.password` — MinIO admin password. **Change before deploying to production.**

### Replicas

* `replicas` — Number of MinIO instances in the distributed cluster (minimum 4, must be even).

<Note>
  MinIO requires at least 4 replicas to form a distributed cluster with erasure coding. For production workloads, 6 or more replicas are recommended. Depending on your organization's default quotas, you may need to request higher limits.
</Note>

### Resources

* `resources.minCpu` / `resources.minMemory` — Minimum CPU and memory guaranteed to each replica.
* `resources.maxCpu` / `resources.maxMemory` — Maximum CPU and memory each replica can use.

### Storage

* `volumeset.capacity` — Initial volume size in GiB per replica (minimum 10).
* `volumeset.autoscaling.enabled` — Automatically expand each volume as it fills. When enabled:
  * `maxCapacity` — Maximum volume size in GiB.
  * `minFreePercentage` — Trigger a scale-up when free space drops below this percentage.
  * `scalingFactor` — Multiply the current capacity by this factor when scaling up.

### Internal Access

* `internalAccess.type` — Controls which workloads can connect to MinIO on ports `9000` and `9001`:

| Type            | Description                                                     |
| --------------- | --------------------------------------------------------------- |
| `none`          | No internal access allowed                                      |
| `same-gvc`      | Allow access from all workloads in the same GVC                 |
| `same-org`      | Allow access from all workloads in the same organization        |
| `workload-list` | Allow access only from specific workloads listed in `workloads` |

<Note>
  Do not set `internalAccess.type` to `none`. MinIO replicas must be able to communicate with each other for distributed mode to function.
</Note>

### Connecting to MinIO

Once deployed, connect to the MinIO S3 API from within the same GVC using the MinIO client:

```bash theme={null}
mc alias set minio http://RELEASE_NAME-minio:9000 USERNAME PASSWORD
```

The web console is available on port `9001` at:

```text theme={null}
https://RELEASE_NAME-minio.GVC_NAME.cpln.app
```
