 ## Install Rook-Ceph for Persistent Storage
 Note: This is unusual but Flex volume path can be different than the default value. values.yaml has the most common flexvolume path configured. In case of errors related to flexvolume please refer to the https://rook.io/docs/rook/v0.9/flexvolume.html#configuring-the-flexvolume-path to find the appropriate flexvolume-path and set it in values.yaml

+# Install Istio configurations for Service connectivity
+
+## Prometheus
+
+```bash
+NOTE: Prometheus is Usually consumed by multiple services,
+Thus we need to expose the Prometheus to all of them.
+
+1. Update "allowedhosts" in values.yaml in prometheus-config-virtualservice
+with all the servies consuming Prometheus
+2. gateways - Name of the Istio gateway to which this
+virtualservice will be connected to
+3. destinationhost - Prometheus service's name
+4. port - port of the Prometheus service
+
+After updating all the required details as per the
+specification of deployment run the below command
+
+cd ~/demo/vnfs/DAaaS/deploy/istio-config/prometheus-config
+
+helm install prometheus-istio-connectivity -n edge1
+```
+## Grafana
+
+```bash
+NOTE: Grafana can be accessed on multiple hosts,
+Update the "allowedhosts" on which the Grafana is
+accessed
+
+1. Update "allowedhosts" in values.yaml in grafana-config-virtualservice
+with all the host/service names on which Grafana is accessed
+2. gateways - Name of the Istio gateway to which this
+virtualservice will be connected to
+3. destinationhost - Grafana service's name
+4. port - Port of the Grafana Service
+
+After updating all the required details as per the
+specification of deployment run the below command
+
+cd ~/demo/vnfs/DAaaS/deploy/istio-config/grafana-config
+
+helm install grafana-istio-connectivity -n edge1
+```
+
+## Minio
+```bash
+NOTE: Minio is a Headless Service. From Istio's perspective
+Headless service can be accessed only by accessing each pod
+of the service.
+
+To access each pod we need a virtualservice and service entry
+which has pod level entries
+
+1. Update "allowedhosts" in values.yaml in minio-istio-connectivity
+with all the host/Service names on which minio is accessed
+2. gateways - Name of the Istio gateway to which this
+virtualservice will be connected to
+3. destinationhost - pod name of minio which needs to be accessed
+Template - <POD_NAME>.<SERVICE_NAME>.<NAMESPACE>.<SVC><CLUSTER>.<LOCAL>
+4. destinationhostPort - Port of the minio pod
+
+After updating all the required details as per the
+specification of deployment run the below command
+
+cd ~/demo/vnfs/DAaaS/deploy/istio-config/minio-config
+
+helm install minio-istio-connectivity -n edge1
