+Helm Installation
+=================
+
+DL-handler consists of three pods- the feeder, admin UI and des. It can be deployed by using helm charts. The following steps guides you launch datalake though helm.
+
+
+Pre-requisites
+~~~~~~~~~~~~~~
+- Datalake postgres should be properly deployed and functional.
+
+- Presto service should be deployed for des deployment.Here is a sample how presto is deployed in the environment.
+
+ Deploying presto service:
+ The package of presto version we are using is v0.0.2:presto-v0.0.2.tar.gz
+
+ #docker build -t presto:v0.0.2 .
+ #docker tag presto:v0.0.2 registry.baidubce.com/onap/presto:v0.0.2
+ #docker push registry.baidubce.com/onap/presto:v0.0.2
+
+ Note: Replace the repository path with your own repository.
+
+ #kubectl -n onap run dl-presto --image=registry.baidubce.com/onap/presto:v0.0.2 --env="MongoDB_IP=192.168.235.11" --env="MongoDB_PORT=27017"
+ #kubectl -n onap expose deployment dl-presto --port=9000 --target-port=9000 --type=NodePort
+
+ Note: MonoDB_IP and Mongo_PORT you can replace this two values with your own configuration.
+
+- The environment should have helm and kubernetes installed.
+
+- Check whether all the charts mentioned in the requirements.yaml file are present in the charts/ folder. If not present, package the respective chart and put it in the charts/ folder.
+
+ For example:
+ .. code-block:: bash
+
+ helm package <dcaegen2-services-common>
+
+
+Deployment steps
+~~~~~~~~~~~~~~~~
+Validate the charts using below commands
+ .. code-block:: bash
+
+ helm lint <dcae-datalake-admin-ui>
+ helm lint <dcae-datalake-feeder>
+ helm lint <dcae-datalake-des>
+
+Deploy the charts using below commands
+ .. code-block:: bash
+
+ helm install <datalake-admin-ui> <dcae-datalake-admin-ui> --namespace onap --set global.masterPassword=<password>
+ helm install <datalake-feeder> <dcae-datalake-feeder> --namespace onap --set global.masterPassword=<password>
+ helm install <datalake-des> <dcae-datalake-des> --namespace onap --set global.masterPassword=<password>
+
+For checking logs of the containers
+ .. code-block:: bash
+
+ kubectl logs -f -n onap <dev-dcae-datalake-admin-ui-843bfsk4f4-btd7s> -c <dcae-datalake-admin-ui>
+ kubectl logs -f -n onap <dev-dcae-datalake-feeder-758bbf547b-ctf6s> -c <dcae-datalake-feeder>
+ kubectl logs -f -n onap <dev-dcae-datalake-des-56465d86fd-2w56c> -c <dcae-datalake-des>
+
+To un-deploy
+ .. code-block:: bash
+
+ helm uninstall <datalake-admin-ui>
+ helm uninstall <datalake-feeder>
+ helm uninstall <datalake-des>
+
