# images

# `prefect_docker.images`

Integrations with Docker Images.

## Functions

### `pull_docker_image` <sup><a href="https://github.com/PrefectHQ/prefect/blob/main/src/integrations/prefect-docker/prefect_docker/images.py#L15" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>

```python  theme={null}
pull_docker_image(repository: str, tag: Optional[str] = None, platform: Optional[str] = None, all_tags: bool = False, docker_host: Optional[DockerHost] = None, docker_registry_credentials: Optional[DockerRegistryCredentials] = None, **pull_kwargs: Dict[str, Any]) -> Union[Image, List[Image]]
```

Pull an image of the given name and return it. Similar to the docker pull command.

If all\_tags is set, the tag parameter is ignored and all image tags will be pulled.

**Args:**

* `repository`: The repository to pull.
* `tag`: The tag to pull; if not provided, it is set to latest.
* `platform`: Platform in the format os\[/arch\[/variant]].
* `all_tags`: Pull all image tags which will return a list of Images.
* `docker_host`: Settings for interacting with a Docker host; if not
  provided, will automatically instantiate a `DockerHost` from env.
* `docker_registry_credentials`: Docker credentials used to log in to
  a registry before pulling the image.
* `**pull_kwargs`: Additional keyword arguments to pass to `client.images.pull`.

**Returns:**

* The image that has been pulled, or a list of images if `all_tags` is `True`.

**Examples:**

Pull prefecthq/prefect image with the tag latest-python3.10.

```python  theme={null}
from prefect import flow
from prefect_docker.images import pull_docker_image

@flow
def pull_docker_image_flow():
    image = pull_docker_image(
        repository="prefecthq/prefect",
        tag="latest-python3.10"
    )
    return image

pull_docker_image_flow()
```
