module: docker_image

short_description: Manage docker images

description:
  - Build, load or pull an image, making the image available for creating containers. Also supports tagging
    an image, pushing an image, and archiving an image to a C(.tar) file.

notes:
  - Building images is done using Docker daemon's API. It is not possible to use BuildKit / buildx this way.

attributes:
  check_mode:

    details:
      - When trying to pull an image, the module assumes this is always changed in check mode.
