- Make the chart and deploy using the following command:

  .. code-block:: bash

    cd oom/kubernetes/
    make dcaegen2-services
    helm install dev-dcaegen2-services dcaegen2-services --namespace <namespace> --set global.masterPassword=<password>

- To deploy only tcagen2:

  .. code-block:: bash

    helm install dev-dcae-tcagen2 dcaegen2-services/components/dcae-tcagen2 --namespace <namespace> --set global.masterPassword=<password>
