title: How to backup Helm3 nginx controller configs and update the running LoadBalancer service?
body: <p>Very new to kubernetes. I've been getting confused by documentation and example differences between Helm2 and 3.</p>
  
  <p>I installed the <code>stable/nginx-ingress</code> chart via <code>helm install app-name stable/nginx-ingress</code>. </p>
  
  <p>1st question:</p>
  
  <p>I need to update the <code>externalTrafficPolicy</code> to <code>Local</code>. I learned later I could have set that during the install process via adding <code>--set controller.service.externalTrafficPolicy=Local</code> to the helm command.</p>
  
  <p>How can I update the LoadBalancer service with the new setting without removing the ingress controller and reinstalling?</p>
  
  <p>2nd question:</p>
  
  <p>Helm3 just downloaded and setup the ingress controller and didn't save anything locally. Is there a way to backup all my my k8s cluster configs (other than the ones I've created manually)?</p>
