+Install (or upgrade) an umbrella Helm Chart, and its subcharts, as separate Helm Releases
The umbrella Helm Chart is broken apart into a parent release and subchart releases.
Subcharts the are disabled (<chart>.enabled=false) will not be installed or upgraded.
--set-string stringArray set STRING values on the command line (can specify multiple or separate values with commas: key1=val1,key2=val2)
-f, --values valueFiles specify values in a YAML file or a URL(can specify multiple) (default [])
--verbose enables full helm install/upgrade output during deploy
+ --set-last-applied set the last-applied-configuration annotation on all objects.This annotation is required to restore services using Ark/Veloro backup restore.
