  name: imagePushToRegistry
  description: Allows you to copy a Docker image from a source container registry  to a destination container registry.
  longDescription: |-
    In case you want to pull an existing image from a remote container registry, a source image and source registry needs to be specified.<br />
    This makes it possible to move an image from one registry to another.

    The imagePushToRegistry is not similar in functionality to containerPushToRegistry (which is currently a groovy based step and only be used in jenkins).
    Currently the imagePushToRegistry only supports copying a local image or image from source remote registry to destination registry.

          Defines the names of the images that will be pushed to the target registry. If empty, names of sourceImages will be used.
          Please ensure that targetImages and sourceImages correspond to each other: the first image in sourceImages should be mapped to the first image in the targetImages parameter.
