Warning since last update about prind HOT 28 CLOSED

I'll reopen this, as i might have a possible solution to monkey patch the running Moonraker instance to contain the requested directories.

from prind.

Thats quite old. v1 might handle container creation in a different way, so that moonraker does not exist at the time we try to copy files into it.
Please give it a try with v2, as mentioned in the Readme: https://github.com/mkuf/prind#getting-started

from prind.

These warnings were introduced with Arksine/moonraker@3a384e6.

Looking at the underlying function, it seems that Moonraker gets these paths from klippy via the socket and there currently is no way of overwriting these locations within moonraker.cfg.

https://github.com/Arksine/moonraker/blob/0d93cf2c398e0ef0b1ff9dc98f81bc30d4804aec/moonraker/components/file_manager/file_manager.py#L131-L138

Have a look at this Branch: moonraker-init
The init-moonraker service copies the klipper directory from the klipper service, so it should always contain the right files for your current deployment.

Imho this is just a dirty hack.
The directories are not essential for using moonraker and therefore only generate a warning.
I guess there was a change in Mainsail, so that these warnings now get propagated to the UI. Which might be useful if they had any impact on the functionality of moonraker.

from prind.

Well, this sounds better than my approach: I was about to just create the directories at their default location (where they make absolutely no sense).

I will try that soon.

from prind.

With fluidd-core/fluidd#505 this is now also present in fluidd.

from prind.

Do you still need me to test it? It's not as easy to install as I would have to change my docker-compose file.

So, if you are convenient it doesn't break anything I would wait until this comes to upstream. However, if you need someone to test it, I can try.

from prind.

It would be great if you could give it a try.
Have a look at the diff here 13f31e2
It's basically just an extra service and a new dependency for the moonraker service. The other lines just rename the existing init service, which is not necessary for testing this change.

-Markus

from prind.

I just tried it out. If I didn't make a mistake, the warnings are still there. Maybe I misconfigured something?

from prind.

Mind sharing your compose file?
Did the init-moonraker service produce any logs?

docker logs init-moonraker

Have any klipper files been copied to the moonraker container?

docker exec -it moonraker ls -al /opt

from prind.

Here's my compose file

I also would like to provide docker logs, however, after pulling the images again, I cannot get moonraker to start.
[edit]
This was a heisenbug. I tried it again, now it started.

$ docker-compose --profile=mainsail up -d

However, init-moonraker didn't create any logs.

Here's the other output:

Seems nothing has been created, or has it?

Your compose file looks fine to me.
I can't recreate this issue and can't pin down what is causing this behaviour for you.

Here are a few things you could try.

Option 1: (preferred) Trigger the init Service again

1. Start the init-moonraker service after the stack has started

docker compose start init-moonraker

2. Inspect the init services' logs and check if klipper directory has been copied

docker compose logs init-moonraker
docker compose exec moonraker ls /opt

3. If the files have been copied, restart the moonraker service

docker compose restart moonraker

Option 2: Manually Copy Files

1. Copy Files to your local disk and then into the moonraker service

docker compose cp klipper:/opt/klipper /tmp
docker compose cp /tmp/klipper moonraker:/opt

2. Restart the moonraker service

docker compose restart moonraker

On an unrelated note, I noticed that the docker:dind Image is only available for x64 and arm64 architectures. This would manifest in an error, if you were on a unsupported arch. I am personally using this Stack on arm/v7 which would not be able to start with this init service.
To circumvent this, we could probably build an image that contains docker ourselves.

from prind.

hm. I use my home server which runs a amd64 architecture.

I can still try to put the directories where Moonraker expects them. It just doesn't seem "correct" but, maybe that's the easiest way...

Still have to try to start init-moonraker manually.

Or maybe it would make sense to raise a feature request in the moonraker repo to get the possibility to configure the path?

from prind.

The options I mentioned above are meant as troubleshooting steps, as I could not reproduce your described behaviour. Manually copying the Files is not the correct long-term solution.

At the moment I would like to bother the Maintainers of the packaged software as little as possible as long as there are viable Workarounds for running their projects in Docker.

from prind.

Sorry to jump in but i have similar problems after updating to latest docker 20.10.14 today, everything worked perfectly before the update.
I also had problem with Pi-hole (irrelevant but worth mentioning)
I'm using debian (bullseye) on an old laptop.

And i have the following errors after replacing my docker-compose.yaml and adding docker-compose.override.yaml

And this with my old docker-compose.yaml

docker-compose.yaml.old.txt
docker-compose.yaml.current.txt
docker-compose.override.yaml.current.txt

from prind.

@gminadak please share your moonraker.cfg and a full moonraker log.

from prind.

@mkuf thank you for your reply
moonraker.cfg.txt
moonraker.log.txt

from prind.

@gminadak
those Policykit Warnings are probably caused my a missing setting.
Have a look at the example:

Also, make sure to use mkuf/moonraker:4b27e5e or later, as described in the v0.5.0 Releasenotes

from prind.

@mkuf by adding
[machine]
provider: systemd_cli

The PolicyKit warnings have gone, after some researching i come across this on GitHub
but as mentioned this feature will be deprecated in the future and the correct solution is to run the
~/moonraker/scripts/set-policykit-rules.sh
I won't lie to you i tried to execute this from docker but it asked for root password for moonraker and I stopped the procedure.
I'm by no means an expert in Docker, klipper or linux.

Thank you for your help.
ps: The suppliedpath errors are still in place

from prind.

Thanks for pointing this out. I did not consider this when implementing the features for v0.5.0.
I'll have to look into handling this with dbus and policykit to be compatible with future moonraker releases, but this will be a separate issue.

Did you test the moonraker-init branch to get rid of the directory warnings, @gminadak?

So the init-moonraker container failed.
What logs did it output?

The errors in init-moonrakers logs indicate that the containers are not available.
From your output, it seems that the moonraker container is missing at the time the init container tries to copy the files.

Which docker compose version are you using?

I'm still wondering how did i miss this step.
Thank you for your help, the problem is now solved.
Worth to mention that the main version still have this problem even after the update.

Great, these changes will soon be merged into main.
Thanks for testing this @gminadak

@speendo
I noticed you use the docker-compose command instead of docker compose. Are you also on compose v1?

from prind.

I gave this a try on my printer, which is equipped with a fairly old udoo quad.
Thanks to its very limited computing power paired with a micro-sd, starting the stack was painfully slow.
The init-moonraker service took almost two minutes to complete. This is way to long, considering it is executed every time the stack is brought up.

So I went ahead and mounted /dev/null in those places where moonraker expects a directory.
This renders the docs and example endpoints of moonraker useless, but gets rid of the Warnings.
