How do I tag a local docker image with ansible docker_image module?

Question

I'm building a local docker image and I'd like to tag it, but I have no idea how the repository field should be filled for a docker image I just built locally.

Is tagging local images even possible with the docker_image module?

Answer 1

Seems that there is better solution with docker_image:

tasks:
  - name: build_image
    docker_image:
      name: test_img:latest     # Name of image, may be with repo path.
      path: .
      state: present
    register: image_build

  - name: tag_version
    docker_image:
      name: test_img:latest     # Equal to name in build task.
      repository: test_img:1.2  # New tag there.
      pull: no
      state: present
    when: image_build.changed

Effect:

    $ docker images
    REPOSITORY   TAG       IMAGE ID            CREATED              SIZE
    test_img     1.2       ab14e8cce7ef        9 seconds ago        142MB
    test_img     latest    ab14e8cce7ef        9 seconds ago        142MB

Works also with pushing to repo (need to change name to full repo path).
