This is where the actual deployment of the components into kubernetes cluster happens. The install script is responsible for identifying the namespace, helm release & parent chart to start the deployment process. It also creates the config map of the recipe file which is later used during uninstall process. Once all the above are done, it will call the below command to deploy the nonrtric components,
