Running it over multiple helm charts required a simple script. Here I use bash to get the helm charts from every namespace in the cluster and then iterate over them, running them through the mapkubeapis tool.

#!/bin/bash


helm list -A | while read line; do

    linearray=($line)

    release=${linearray[0]}
    namespace=${linearray[1]}

    helm mapkubeapis --namespace $namespace --dry-run $release

done
