module: openshift_import_image

short_description: Import the latest image information from a tag in a container image registry.

version_added: "2.2.0"

author:
  - Aubin Bikouo (@abikouo)

description:
  - Image streams allow you to control which images are rolled out to your builds and applications.
  - This module fetches the latest version of an image from a remote repository and updates the image stream tag
    if it does not match the previous value.
  - Running the module multiple times will not create duplicate entries.
  - When importing an image, only the image metadata is copied, not the image contents.
  - Analogous to C(oc import-image).
