Hey! You should just be able to pass in a dict to `args`

There’s an example here: <https://github.com/pulumi/pulumi-docker/blob/5da13f5d840f13639b6917e54b122d0c59cfffbf/examples/aws-py/__main__.py>

Have you tried this?

```flask_image = docker.Image("flask-dockerimage",
    image_name=app_ecr_repo_repository_url,
    build=docker.DockerBuild(
        context="./frontend",
        args={
            "db_host_address": db_host_address,
            "db_host_port": db_host_port,
            "db_name": db_name,
            "db_user": db_user,
        }
    ),
    skip_push=False,
    registry=app_registry
)```

Hi <@U01038HJ93R> - thanks for your help! It turned out I had to do the work of creating the docker.Image within the `apply` statement in order to get things to work.  It wasn’t accepting the Outputs within the dict directly.

It’s not recommended to create resources within an `apply` - because of the unexpected behavior related to `preview` and the resource graph not being calculated correctly. There’s generally a way to refactor the code so that creating the resource within an apply is not necessary.
