+# 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
+```
