I have some issues when trying to build a Python Docker image for my application. When I export the image to a local tar file and import the image I get an error message telling me that there is no command specified.
Anyone got an idea how to fix this?

Hey, I'm taking a look.
There's an argument in the command that jumped out to me: "--access-logfile -", should be split in two.
Btw, you'll need to change the optional to a kwarg because otherwise it's going to break in the next release .with_default_args(args=[...]).

Tried to split in two but same issue

Do it anyway, the problem is elsewhere.
pale pumice
Ah didn't add the args=[..]
analog inlet
I'll need to strip down your code to a minimal example since I don't have your files.

Ah didn't add the `args=[..]`
No, it's allowed now, but it won't in the next release. 👉 https://github.com/dagger/dagger/issues/4182
I ran a simpler version (without stuff from src) successfully. Can you provide the command you're using and what you get in the logs?
This is what I ran:
import sys
import anyio
import dagger
import os
async def main():
# Create Dagger Client
async with dagger.Connection(dagger.Config(log_output=sys.stderr)) as client:
deploy_image = os.getenv("PYTHON_IMAGE", "python:3.10-slim")
# map root project folder as src folder
src = client.host().directory(".")
# base pipeline with required Python packages
build = (
client.container().pipeline("build")
.from_(deploy_image)
.with_mounted_cache("/root/.cache", client.cache_volume("pip"))
.with_mounted_directory("/src", src)
.with_workdir("/src")
.with_exec(["pip", "install", "."])
)
deploy = (
client.container()
.pipeline("deploy")
.from_(deploy_image)
.with_env_variable("PYTHONPATH", "/")
.with_directory(
"/usr/local/lib/python3.10/site-packages",
build.directory("/usr/local/lib/python3.10/site-packages"),
)
.with_exposed_port(8080)
.with_default_args(
args=[
"whoami",
]
)
)
await deploy.export("/tmp/kea-netbox-helper.tar")
if __name__ == "__main__":
anyio.run(main)
Oh, you said the error is when importing... you mean into the docker engine?
pale pumice
yes, after importing in docker engine
docker import /tmp/kea-netbox-helper.tar
docker run --rm <image_id>
docker: Error response from daemon: No command specified.
See 'docker run --help'.
❯ docker load -i /tmp/kea-netbox-helper.tar

Ah yes, import is just he filesystem.
Have you seen the documentation? https://docs.dagger.io/252029/load-images-local-docker-engine

Thanks for clearing this up. Didn't had much sleep... 😴

That's alright, me neither! 🙂
