Pass build args to a Dockerfile with PythonSDK | Dagger | Page 1

Hi,

I´m trying to pass build args starting from a Dockerfile that I have in my repo. Which is the equivalent code in Python from this https://docs.dagger.io/sdk/cue/966156/docker/#build-arguments ?

I tried to use this two functions, but I didn't figure out how to use them.

https://dagger-io.readthedocs.io/en/sdk-python-v0.1.1/api.html#dagger.api.gen.Container.with_env_variable

https://dagger-io.readthedocs.io/en/sdk-python-v0.1.1/api.html#dagger.api.gen.Container.with_default_args

My code:

async def build_and_publish():

    async with dagger.Connection(dagger.Config(log_output=sys.stderr)) as client:

        src_id = await client.host().workdir("../").id()

        # Read images file
        with open('.dagger/images.json') as imgs_file:

            images = json.load(imgs_file)['images']

        for image in images:

            print(f"Building {image['tag']}")

            print(f"Dockerfile: {image['dockerfile']} ...")

            container = (

                client

                .container()

            )

            # Split build args on newlines
            build_args = image['build_args'].splitlines()

            print(f"Build args: {build_args}")

            container = (

                container.with_default_args(build_args)

            )

            container = (

                container

                .build(src_id, image['dockerfile'])

            )

            print(f"Publishing {image['tag']}")

            await container.publish(image['tag'])

``` Thanks in advance

The docker package | Dagger

The universe.dagger.io module is meant to provide higher level abstractions on top of core actions. Of these, the universe.dagger.io/docker package provides a general base for building and running docker images.
