## List of metrics exposed by MinIO

- MinIO exports Prometheus compatible data by default as an authorized endpoint at `/minio/v2/metrics/cluster`. 
- MinIO exports Prometheus compatible data by default which is bucket centric as an authorized endpoint at `/minio/v2/metrics/bucket`.
- MinIO exports Prometheus compatible data by default which is node centric as an authorized endpoint at `/minio/v2/metrics/node`.

Example: Limit a MinIO cluster to accept at max 1600 simultaneous S3 API requests across 8 servers, and set the wait deadline of *2 minutes* per API operation.

```sh
export MINIO_API_REQUESTS_MAX=1600
export MINIO_API_REQUESTS_DEADLINE=2m
export MINIO_ROOT_USER=your-access-key
export MINIO_ROOT_PASSWORD=your-secret-key
minio server http://server{1...8}/mnt/hdd{1...16}
```

or

```sh

```

### 2. Set the MinIO-KES configuration

```sh
export MINIO_KMS_KES_ENDPOINT=https://play.min.io:7373
export MINIO_KMS_KES_KEY_FILE=root.key
export MINIO_KMS_KES_CERT_FILE=root.cert
export MINIO_KMS_KES_KEY_NAME=my-minio-key
```

### 3. Start the MinIO Server

```sh
export MINIO_ROOT_USER=minio
export MINIO_ROOT_PASSWORD=minio123
minio server ~/export
```

#### Credentials

On MinIO admin credentials or root credentials are only allowed to be changed using ENVs namely `MINIO_ROOT_USER` and `MINIO_ROOT_PASSWORD`.

```sh
export MINIO_ROOT_USER=minio
export MINIO_ROOT_PASSWORD=minio13
minio server /data
```

#### Site

```
KEY:
site  label the server and its location

ARGS:
name     (string)    name for the site e.g. "cal-rack0"

```

## Using WebIdentity API

```
export MINIO_ROOT_USER=minio
export MINIO_ROOT_PASSWORD=minio123
export MINIO_IDENTITY_OPENID_CONFIG_URL=https://accounts.google.com/.well-known/openid-configuration
export MINIO_IDENTITY_OPENID_CLIENT_ID="843351d4-1080-11ea-aa20-271ecba3924a"
# Optional: Allow to specify the requested OpenID scopes (OpenID only requires the `openid` scope)
#export MINIO_IDENTITY_OPENID_SCOPES="openid,profile,email"

`/<user-running-minio>/.minio/certs`.

*Tip*: In a standard Kubernetes configuration, this will be `/root/.minio/certs`. Kubernetes will mount the secrets volume read-only,

```bash
helm install --name my-release -f values.yaml minio/minio
```

### Persistence

This chart provisions a PersistentVolumeClaim and mounts corresponding persistent volume to default location `/export`. You'll need physical storage available in the Kubernetes cluster for this to work. If you'd rather use `emptyDir`, disable PersistentVolumeClaim by:

```bash
helm install --set persistence.enabled=false minio/minio
```

### 5. Setup MinIO with OpenID configuration URL

MinIO server expects environment variable for OpenID configuration url as `MINIO_IDENTITY_OPENID_CONFIG_URL`, this environment variable takes a single entry.

```
export MINIO_IDENTITY_OPENID_CONFIG_URL=https://localhost:9443/oauth2/oidcdiscovery/.well-known/openid-configuration
export MINIO_IDENTITY_OPENID_CLIENT_ID="843351d4-1080-11ea-aa20-271ecba3924a"
minio server /mnt/data

### 3. Setup MinIO with etcd

MinIO server expects environment variable for etcd as `MINIO_ETCD_ENDPOINTS`, this environment variable takes many comma separated entries.

```
export MINIO_ETCD_ENDPOINTS=http://localhost:2379
minio server /data
```

```sh
export MINIO_ROOT_USER=<TENANT1_ACCESS_KEY>
export MINIO_ROOT_PASSWORD=<TENANT1_SECRET_KEY>
minio server --address :9001 http://192.168.10.1{1...4}/data/tenant1

export MINIO_ROOT_USER=<TENANT2_ACCESS_KEY>
export MINIO_ROOT_PASSWORD=<TENANT2_SECRET_KEY>
minio server --address :9002 http://192.168.10.1{1...4}/data/tenant2

export MINIO_ROOT_USER=<TENANT3_ACCESS_KEY>
