   File      | Description |
  | ----------- | ----------- |
  | **emco-db-0.1.0.tgz**      | Includes database packages for mongo & etcd       |
  | **emco-services-0.1.0.tgz**   | Includes packages for all EMCO services like orchestrator, ncm, rsync etc        |

  | **emco-0.1.0.tgz**   | Includes all charts including database, all services and tools        |


**2. Deploy EMCO Packages for Databases and Services**

`$ helm install dist/packages/emco-db-0.1.0.tgz --name emco-db --namespace emco`

`$ helm install dist/packages/emco-services-0.1.0.tgz --name emco-services --namespace emco`

**3. Deploy tools (Optional)**

`$ helm install dist/packages/emco-tools-0.1.0.tgz --name emco-tools --namespace emco`

NOTE: Deploy the Chart emco-0.1.0.tgz to deploy all packages including database, services and tools.

`$ helm install dist/packages/emco-0.1.0.tgz --name emco --namespace emco`


**4. To check logs of the different Microservices check fluentd logs**

`kubectl logs emco-tools-fluentd-0 -n emco | grep orchestrator`


**5. Delete all packages**

`$ helm delete emco-services --purge`

`$ helm delete emco-db --purge`

Optional if tools were installed

`$ helm delete emco-tools --purge`

NOTE: If the Chart emco-0.1.0.tgz was deployed

`$ helm delete emco --purge`


**6. Delete local helm repo**

`make repo-stop`

### Known Issues

After deleting the db package and before installing the package again following error happens:

`Error: release emco-db failed: object is being deleted: persistentvolumes "emco-db-emco-etcd-data-0" already exists`

Workarounds:

* remove the  finalizers section using `kubectl edit persistentvolumes emco-db-emco-etcd-data-0`
* or, if appropriate, delete the entire namespace using `kubectl delete namespace emco`
