failing to push with additional_tags when source has no tag configure

[kalensk]

How can I push a tag that is "not" known upfront when specifying the resource? That is, how to push a tag that is only known when building the image? I thought additional_tags would satisfy this need, but is failing.

My source does not specify a tag such as:

  - name: image_registry
    type: registry-image
    icon: docker
    source:
      username: ((user))
      password: ((pw))
      repository: gcr.io/my-project/image

My put to push the tag has the following where the additional_tags/tags file contains a single tag "dev" with no quotes:

- put: image_registry
  params:
    image: image/image.tar
    additional_tags: additional_tags/tags

The put step fails with:

Reproduction steps

1. Configure a source without specifying a tag
2. Configure a put step to push a tag created in that task using additional_tags

Expected behavior

The image is successfully pushed with the additional_tags.

There clearly needs to be a way to push a tag without needing to specify one up-front in the source resource. This is because a tag may not be known until the actual image building task.
