In general, upgrade can be done by command helm upgrade open-local [path of chart].
If you run helm upgrade and encounter errors such as "Forbidden" or "field is immutable", you can reinstall open-local:
- delete open-local
- helm delete open-local
- install open-local
- helm install open-local [path of chart]
- observe whether the components are ready
- watch kubectl get po -nkube-system -l app=open-local
