It would be nice to have an go-tempalte for pod.metrics and pod resources with CSV export to get a nice overview. Or combine both on one?

{{$printf_format := "%-25s\t%-25s\t%-25s\t%s\t%-50s\n" }}

{{- printf $printf_format "NAMESPACE" "POD NAME" "CONTAINER NAME" "RESOURCES" "USAGE" -}}
{{- range .items -}}
    {{- if eq .kind "PodMetrics" -}}

        {{$namespace := .metadata.namespace -}}
        {{$pod_name := .metadata.name}}
        {{- range .containers -}}
            {{- if ne .name "POD" -}}
                {{- printf $printf_format $namespace $pod_name .name "-" .usage -}}
            {{- end -}}
        {{- end -}}

    {{- end -}}
    {{- if eq .kind "Pod" -}}
            {{$namespace := .metadata.namespace -}}
            {{$pod_name := .metadata.name}}

Ugly as hell
