cannot use strategicMergePatches feature of helmfiles

[mestuddtc]

I followed (documentation from helmfiles)[https://github.com/roboll/helmfile/blob/master/docs/advanced-features.md] to configure resources in a way not supported by the helm chart values. jx admin log shows the boot job failing:

"ingress-nginx" has been added to your repositories

in ./helmfile.yaml: in .helmfiles[3]: in helmfiles/nginx/helmfile.yaml: [exec: "kustomize": executable file not found in $PATH

COMMAND:
  kustomize build /tmp/chartify892838689/nginx-ingress/ingress-nginx --output /tmp/chartify892838689/nginx-ingress/ingress-nginx/all.patched.yaml

OUTPUT:
]

This particular instance, I need to use AWS ACM certificates, so am modifying the nginx ingress to use them and still redirect HTTP to HTTPS. (see kubernetes/ingress-nginx#2724)
