• both static-site and staticSite are used in var names. I guess only one of them, staticSite should be
• name: {{ .Chart.Name }}, name: {{ .Release.Name }} can you copy the same naming approach that we use in onechart? I don't think .Chart.Name is used.
• builtAssets is not used in the implementation. I think that needs to be configurable as build scripts output dir vary
• I would have used the same configmap approach as with the onechart solution. Gives a nicer separation, it would also handle multiline commands. Not sure if needed though.
