When you nest values in yaml like

server:
  spec:
    cpu: 0.5

You use it in helm as {{ .Values.server.spec.cpu | default 0.5 }}, which works fine till you try the values as not defined
e.g

gerritjvv

#!/usr/bin/env bash

echo "ingress deployments services statefulset" | \
 xargs -n 1 -I ktype \
 sh -c 'kubectl get ktype | tail -n+2 | awk '\''{print $1}'\'' | xargs -t -P 2 -I resource sh -c '\''kubectl get ktype resource -o yaml > resource.yml'\'''
 
 # echo "ingress deployments services statefulset" | xargs -n 1 -I ktype sh -c  
 # ^^ runs a command for each ingress deployments etc..  the -I parameter is string substitution, i.e where ever it sees ktype it will put the ingress deployments etc read from stdin.
 
# kubectl get ktype | tail -n+2 | awk '{print $1}' | xargs -t -P 2 -I resource sh -c 'kubectl get ktype resource -o yaml > resource.yml'

Advice on how to reduce code size

There are use cases where you need to reduce the total size of your python deployed code including library code.

E.g:

I have to deploy a layer with pandas and numpy etc. Total size cannot be over 260mb.
