-Vars are used to capture text from one resource's field
-and insert that text elsewhere - a reflection feature.
-
-For example, suppose one specifies the name of a k8s Service
-object in a container's command line, and the name of a
-k8s Secret object in a container's environment variable,
-so that the following would work:
-
-```yaml
-# consider it is a deployment
-containers:
-  - image: myimage
-    command: ["start", "--host", "$(MY_SERVICE_NAME)"]
-    env:
-    - name: SECRET_TOKEN
-      value: $(SOME_SECRET_NAME)
-    livenessProbe:
-       httpGet:
-         path: /healthz
-         # it enables the parser to lookup this field
-         port: $(APP_PORT)
-```
-
-To do so, add an entry to `vars:` as follows:
-
-```yaml
-apiVersion: kustomize.config.k8s.io/v1beta1
-kind: Kustomization
-
-configMapGenerator:
-- name: my-config
-  literals:
-  - MY_PORT=8080
-
-vars:
-- name: SOME_SECRET_NAME
-  objref:
-    kind: Secret
-    name: my-secret
-    apiVersion: v1
-- name: MY_SERVICE_NAME
-  objref:
-    kind: Service
-    name: my-service
-    apiVersion: v1
-  fieldref:
-    fieldpath: metadata.name
-- name: ANOTHER_DEPLOYMENTS_POD_RESTART_POLICY
-  objref:
-    kind: Deployment
-    name: my-deployment
-    apiVersion: apps/v1
-  fieldref:
-    fieldpath: spec.template.spec.restartPolicy
-# it exports a value as `APP_PORT` 
-# from `ConfigMap` named `my-config`
-# in `data.MY_PORT`
-- name: APP_PORT
-  objref:
-    kind: ConfigMap
-    name: my-config
-    apiVersion: v1
-  fieldref:
-    fieldpath: data.MY_PORT
-    
-configurations:
-  - lookup.yaml
-```
-
-Define the consuming resource(s) and the field(s) inside need to lookup.
-
-```yaml
-# lookup.yaml
-varReference:
-  # the path of field that you want the parser to lookups and replace.
-  - path: spec/template/spec/containers/livenessProbe/httpGet/port
-    kind: Deployment
-```
-
-A var is a tuple of variable name, object
-reference and field reference within that object.
-That's where the text is found.
-
-The field reference is optional; it defaults to
-`metadata.name`, a normal default, since kustomize
-is used to generate or modify the names of
-resources.
-
-At time of writing, only string type fields are
-supported.  No ints, bools, arrays etc.  It's not
-possible to, say, extract the name of the image in
-container number 2 of some pod template.
-
-A variable reference, i.e. the string '$(FOO)',
-can only be placed in particular fields of
-particular objects as specified by kustomize's
-configuration data.
-
-The default config data for vars is at [/api/konfig/builtinpluginconsts/varreference.go](https://github.com/kubernetes-sigs/kustomize/blob/master/api/konfig/builtinpluginconsts/varreference.go)
-Long story short, the default targets are all
-container command args and env value fields.
-
-Vars should _not_ be used for inserting names in
-places where kustomize is already handling that
-job.  E.g., a Deployment may reference a ConfigMap
-by name, and if kustomize changes the name of a
-ConfigMap, it knows to change the name reference
-in the Deployment.
