## Mounting a sub-application

If you need to mount a sub-application (as described in [Sub Applications - Mounts](sub-applications.md){.internal-link target=_blank}) while also using a proxy with `root_path`, you can do it normally, as you would expect.

$endIndex := add $factor $nodeCount }}{{ $beginIndex := mul $i $nodeCount }} {{ $scheme }}://{{ template `minio.fullname` $ }}-{{ `{` }}{{ $beginIndex }}...{{ sub $endIndex 1 }}{{ `}`}}.{{ template `minio.fullname` $ }}-svc.{{ $.Release.Namespace }}.svc.{{ $.Values.clusterDomain }}{{if (gt $drivesPerNode 1)}}{{ $bucketRoot }}-{{ `{` }}0...{{ sub $drivesPerNode 1 }}{{ `}` }}{{ else }}{{ $bucketRoot }}{{end }}{{- end }} -S {{ .Values.certsPath }} --address :{{ .Values.minioAPIPort }} --console-address...

  storageClass: ""
  volumeName: ""
  accessMode: ReadWriteOnce
  size: 500Gi

  ## If subPath is set mount a sub folder of a volume instead of the root of the volume.
  ## This is especially handy for volume plugins that don't natively support sub mounting (like glusterfs).
  ##
  subPath: ""

## Expose the MinIO service to be accessed from outside the cluster (LoadBalancer service).

## Request, System and Cluster Metrics

At a high level metrics are grouped into three categories, listed in the following sub-sections. The path in each of the tables is relative to the top-level endpoint.

### Request metrics 

These are metrics about requests served by the (current) node.
