def kind
  wrapper_key =~ /configMap/ ? "ConfigMap" : "Secret"
end

#target_key ⇒ Object

The target key of the hashable value is that key used for find value to add hash

envFrom:
- secretRef:             <--- wrapper_key
    name: demo-secret    <--- target_key is 'name' from wrapper_map[wrapper_key]

def target_key
  wrapper_map[wrapper_key]
end

#wrapper_key ⇒ Object

The wrapper field is nested right above the item with the hashable value. Simple example:

envFrom:
- secretRef:           <--- wrapper_key
    name: demo-secret  <--- target_key is 'name' from wrapper_map[wrapper_key]

More complex example where there’s a configMap.name key also on the same level.

volumes:
- name: config-map-volume
  configMap:
    name: demo-config-map

Note: Wont work for case when there’s are 2 matching wrapper_map keys, but don’t think Kubernetes allows 2 matching wrapper_map keys. Example: This is invalid Kubernetes YAML.

volumes:
- name: config-map-volume
  configMap:
    name: demo-config-map
  secretRef:
    name: demo-seret

def wrapper_key
  @item.keys.find { |k| wrapper_map.keys.include?(k) } # this key used for map[wrapper_key]
end

#wrapper_map ⇒ Object

wrapper element to key that stores the hashable value
