### Run Multiple Clusters

> cluster1

```sh
export MINIO_ETCD_ENDPOINTS="http://remote-etcd1:2379,http://remote-etcd2:4001"
export MINIO_DOMAIN=domain.com
export MINIO_PUBLIC_IPS=44.35.2.1,44.35.2.2,44.35.2.3,44.35.2.4
minio server http://rack{1...4}.host{1...4}.domain.com/mnt/export{1...32}
```

> cluster2

```sh
export MINIO_ETCD_ENDPOINTS="http://remote-etcd1:2379,http://remote-etcd2:4001"

### 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
```

const (
	Endpoints     = "endpoints"
	PathPrefix    = "path_prefix"
	CoreDNSPath   = "coredns_path"
	ClientCert    = "client_cert"
	ClientCertKey = "client_cert_key"

	EnvEtcdEndpoints     = "MINIO_ETCD_ENDPOINTS"
	EnvEtcdPathPrefix    = "MINIO_ETCD_PATH_PREFIX"
	EnvEtcdCoreDNSPath   = "MINIO_ETCD_COREDNS_PATH"
	EnvEtcdClientCert    = "MINIO_ETCD_CLIENT_CERT"
	EnvEtcdClientCertKey = "MINIO_ETCD_CLIENT_CERT_KEY"
)
