Hi - would really appreciate some insight into the following:

db_user = os.environ['DB_USER']

# Create Output[Mapping] for use with args[Input[Mapping[str,str]]]
gatheredDBOutput = pulumi.Output.all(
    db_host_address, 
    db_host_port, 
    db_name
)

def createBuildArgs(host_address, host_port, name, user):
    return json.dumps({
        "db_host_address": host_address,
        "db_host_port": host_port,
        "db_name": name,
        "db_user": user,
    })

buildArgs = gatheredDBOutput.apply(lambda args: 
    createBuildArgs(args[0], args[1], args[2], db_user)
)

flask_image = docker.Image("flask-dockerimage",
    image_name=app_ecr_repo_repository_url,
    build=docker.DockerBuild(
        context="./frontend",
        args=buildArgs
    ),
    skip_push=False,
    registry=app_registry
)

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

args

Hi @red-match-15116 - 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.
