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

+#### Troubleshooting Rook-Ceph installation
+
+In case your machine had rook previously installed successfully or unsuccessfully
+and you are attempting a fresh installation of rook operator, you may face some issues.
+Lets help you with that.
+
+* First check if there are some rook CRDs existing :
+```
+kubectl get crds | grep rook
+```
+If this return results like :
+```
+otc@otconap7 /var/lib/rook $ kc get crds | grep rook
+cephblockpools.ceph.rook.io 2019-07-19T18:19:05Z
+cephclusters.ceph.rook.io 2019-07-19T18:19:05Z
+cephfilesystems.ceph.rook.io 2019-07-19T18:19:05Z
+cephobjectstores.ceph.rook.io 2019-07-19T18:19:05Z
+cephobjectstoreusers.ceph.rook.io 2019-07-19T18:19:05Z
+volumes.rook.io 2019-07-19T18:19:05Z
+```
+then you should delete these previously existing rook based CRDs by generating a delete
+manifest file by these commands and then deleting those files:
+```
+helm template -n rook . -f values.yaml > ~/delete.yaml
+kc delete -f ~/delete.yaml
+```
+
+After this, delete the below directory in all the nodes.
+```
+sudo rm -rf /var/lib/rook/
+```
+Now, again attempt :
+```
+helm install -n rook . -f values.yaml --namespace=rook-ceph-system
+```
+
+## Install Operator package
+### Build docker images
+#### collectd-operator
+```bash
+cd $DA_WORKING_DIR/../microservices
+
+## Note: The image tag and respository in the Collectd-operator helm charts needs to match the IMAGE_NAME
+IMAGE_NAME=dcr.cluster.local:32644/collectd-operator:latest
+./build_image.sh collectd-operator $IMAGE_NAME
+```
+#### visualization-operator
+```bash
+cd $DA_WORKING_DIR/../microservices
+
+## Note: The image tag and respository in the Visualization-operator helm charts needs to match the IMAGE_NAME
+IMAGE_NAME=dcr.cluster.local:32644/visualization-operator:latest
+./build_image.sh visualization-operator $IMAGE_NAME
+```
+
+### Install the Operator Package
```bash
cd $DA_WORKING_DIR/operator
helm install -n operator . -f values.yaml --namespace=operator
```bash
kubectl get pods -n operator

```
+#### Troubleshooting Operator installation
+Sometimes deleting the previously installed Operator package will fail to remove all operator pods. To troubleshoot this ensure these following steps.
-#### Install Collection package
+1. Make sure that all the other deployments or helm release is deleted (purged). Operator package is a baseline package for the applications, so if the applications are still running while trying to delete the operator package might result in unwarrented state.
+
+2. Delete all the resources and CRDs associated with operator package.
+```bash
+#NOTE: Use the same release name and namespace as in installation of operator package in the previous section
+cd $DA_WORKING_DIR/operator
+helm template -n operator . -f values.yaml --namespace=operator > ../delete_operator.yaml
+cd ../
+kubectl delete -f delete_operator.yaml
+```
+## Install Collection package
Note: Collectd.conf is avaliable in $DA_WORKING_DIR/collection/charts/collectd/resources/config directory. Any valid collectd.conf can be placed here.
```bash
Default (For custom collectd skip this section)
5. Edit the values.yaml and change the image repository and tag using
COLLECTD_IMAGE_NAME appropriately.
6. Place the collectd.conf in
- $DA_WORKING_DIR/collection/charts/collectd/resources/config
+ $DA_WORKING_DIR/collection/charts/collectd/resources
7. cd $DA_WORKING_DIR/collection
8. helm install -n cp . -f values.yaml --namespace=edge1
cp13-prometheus-prometheus NodePort 10.43.26.155 <none> 9090:30090/TCP
prometheus-operated ClusterIP None <none> 9090/TCP
```
+#### Configure Collectd Plugins
+1. Using the sample [collectdglobal.yaml](microservices/collectd-operator/examples/collectd/collectdglobal.yaml), Configure the CollectdGlobal CR
+2. If there are additional Types.db files to update, Copy the additional types.db files to resources folder.
+3. Create a ConfigMap to load the types.db and update the configMap with name of the ConfigMap created.
+4. Create and configure the required CollectdPlugin CRs. Use these samples as a reference [cpu_collectdplugin_cr.yaml](microservices/collectd-operator/examples/collectd/cpu_collectdplugin_cr.yaml), [prometheus_collectdplugin_cr.yaml](microservices/collectd-operator/examples/collectd/prometheus_collectdplugin_cr.yaml).
+4. Use the same namespace where the collection package was installed.
+5. Assuming it is edge1, create the config resources that are applicable. Apply the following commands in the same order.
+```yaml
+# Note:
+## 1. Create Configmap is optional and required only if additional types.db file needs to be mounted.
+## 2. Add/Remove --from-file accordingly. Use the correct file name based on the context.
+kubectl create configmap typesdb-configmap --from-file ./resource/[FILE_NAME1] --from-file ./resource/[FILE_NAME2]
+kubectl create -f edge1 collectdglobal.yaml
+kubectl create -f edge1 [PLUGIN_NAME1]_collectdplugin_cr.yaml
+kubectl create -f edge1 [PLUGIN_NAME2]_collectdplugin_cr.yaml
+kubectl create -f edge1 [PLUGIN_NAME3]_collectdplugin_cr.yaml
+...
+```
+#### Configure Grafana Datasources
+Using the sample [prometheus_grafanadatasource_cr.yaml](microservices/visualization-operator/examples/grafana/prometheus_grafanadatasource_cr.yaml), Configure the GrafanaDataSource CR by running the command below
+```yaml
+kubectl create -f [DATASOURCE_NAME1]_grafanadatasource_cr.yaml
+kubectl create -f [DATASOURCE_NAME2]_grafanadatasource_cr.yaml
+...
+```
-#### Install Minio Model repository
+## Install Minio Model repository
* Prerequisite: Dynamic storage provisioner needs to be enabled. Either rook-ceph ($DA_WORKING_DIR/00-init) or another alternate provisioner needs to be enabled.
```bash
cd $DA_WORKING_DIR/minio
helm install -n minio . -f values.yaml --namespace=edge1
```
-#### Onboard an Inference Application
+## Install Messaging platform
+
+We have currently support strimzi based kafka operator.
+Navigate to ```$DA_WORKING_DIR/deploy/messaging/charts/strimzi-kafka-operator``` directory.
+Use the below command :
+```
+helm install . -f values.yaml --name sko --namespace=test
+```
+
+NOTE: Make changes in the values.yaml if required.
+
+Once the strimzi operator ready, you shall get a pod like :
+
+```
+strimzi-cluster-operator-5cf7648b8c-zgxv7 1/1 Running 0 53m
+```
+
+Once this done, install the kafka package like any other helm charts you have.
+Navigate to dir : ```$DA_WORKING_DIRdeploy/messaging``` and use command:
+```
+helm install --name kafka-cluster charts/kafka/
+```
+
+Once this done, you should have the following pods up and running.
+
+```
+kafka-cluster-entity-operator-b6557fc6c-hlnkm 3/3 Running 0 47m
+kafka-cluster-kafka-0 2/2 Running 0 48m
+kafka-cluster-kafka-1 2/2 Running 0 48m
+kafka-cluster-kafka-2 2/2 Running 0 48m
+kafka-cluster-zookeeper-0 2/2 Running 0 49m
+kafka-cluster-zookeeper-1 2/2 Running 0 49m
+kafka-cluster-zookeeper-2 2/2 Running 0 49m
+```
+
+You should have the following services when do a ```kubectl get svc```
+
+```
+kafka-cluster-kafka-bootstrap ClusterIP 10.XX.YY.ZZ <none> 9091/TCP,9092/TCP,9093/TCP 53m
+kafka-cluster-kafka-brokers ClusterIP None <none> 9091/TCP,9092/TCP,9093/TCP 53m
+kafka-cluster-zookeeper-client ClusterIP 10.XX.YY.ZZ <none> 2181/TCP 55m
+kafka-cluster-zookeeper-nodes ClusterIP None <none> 2181/TCP,2888/TCP,3888/TCP 55m
+```
+#### Testing messaging
+
+You can test your kafka brokers by creating a simple producer and consumer.
+
+Producer :
+```
+kubectl run kafka-producer -ti --image=strimzi/kafka:0.12.2-kafka-2.2.1 --rm=true --restart=Never -- bin/kafka-console-producer.sh --broker-list kafka-cluster-kafka-bootstrap:9092 --topic my-topic
+ ```
+ Consumer :
+ ```
+
+kubectl run kafka-consumer -ti --image=strimzi/kafka:0.12.2-kafka-2.2.1 --rm=true --restart=Never -- bin/kafka-console-consumer.sh --bootstrap-server kafka-cluster-kafka-bootstrap:9092 --topic my-topic --from-beginning
+```
+
