imageTags problem

[fatihafizoglu]

Here is a piece of my kustomization.yaml:

imageTags:
  - name: alpine
    newTag: 3.6

When I execute kustomize build I got this error:

Error: json: cannot unmarshal number into Go struct field ImageTag.newTag of type string

Version tags like 5.5.0 or v3.5 won't cause problems but this one causes failure.

Try to place quotes around the tag name. The tag needs to be a string, but without quotes, YAML will treat this as a number, if it can. 5.5.0 and v3.5 cannot be parsed as a number, while 3.6 can. That's why it fails.
