}

    err := manager.RegisterSingleHandler(grid.HandlerDiskInfo, handler)
```

Sample call:
```go
    // Get a connection to the remote host
    conn := manager.Connection(host)
	
    payload := []byte("request")
    response, err := conn.SingleRequest(ctx, grid.HandlerDiskInfo, payload)
```

If the error type is `*RemoteErr`, then the error was returned by the remote server. Otherwise it is a local error.

        - CNI installer will try to look for the config file under the mounted CNI net dir based on file name extensions (`.conf`, `.conflist`)
        - the file name can be explicitly set by `CNI_CONF_NAME` env var
        - the program inserts `CNI_NETWORK_CONFIG` into the `plugins` list in `/etc/cni/net.d/${CNI_CONF_NAME}`
    - the actual code is in pkg/install - including a readiness probe, monitoring.

To deploy Distributed MinIO on Docker Compose, please download [docker-compose.yaml](https://github.com/minio/minio/blob/master/docs/orchestration/docker-compose/docker-compose.yaml?raw=true) and [nginx.conf](https://github.com/minio/minio/blob/master/docs/orchestration/docker-compose/nginx.conf?raw=true) to your current working directory. Note that Docker Compose pulls the MinIO Docker image, so there is no need to explicitly download MinIO binary. Then run one of the below commands

```sh
openssl rsa -in private-pkcs8-key.key -aes256 -passout pass:PASSWORD -out private.key
```
