[Setup-TraefikContainerForBcContainer] Provider connection error error during connect: Get \"http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.24/version\": open //./pipe/docker_engine: message readmode pipes not supported In the default daemon configuration on Windows

[christianbraeunlich]

Hello there, I was trying to setup some containers using traefik after a long period of time. I think it used to work right of the bat for me, but now I catch some errors which I think is mostly related to docker itself. I like to share the information, get some guidance into the right direction - which is very much appreciated - and maybe contribute if neccessary. Thanks in advance!

FYI: I got it working after a few days: with the latest image of tobiasfenster/traefik-for-windows:2.9.6 and manually creating the labels for the container. I've also had to migrate the scripts to Traefik 2 and replace pipe/docker_engine with pipe/docker_engine_windows (this is not only true to the traefik.yml but also when mounting the volume.

Describe the issue

When executing the Setup-TraefikContainerForBcContainer.ps1 script it successfully creates the traefik container (tobiasfenster/traefik-for-windows:1.7.34). Opening the terminal of this container shows that there was no connection established to the Docker Daemon: Provider connection error error during connect: Get \"http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.24/version\": open //./pipe/docker_engine: message readmode pipes not supported In the default daemon configuration on Windows.

This blocks traefik from being able to discover the lables of other docker containers. If I would be able to select a docker daemon I could select npipe:////./pipe/docker_engine_windows and I expect it to work.

Maybe you have some insights for me as I also think my setup is a bit off due to the _windows suffix.

Thank you for your help!

Scripts used to create container and cause the issue

So far, so good. Now if we take a look into the terminal of the created container we will see lots of errors:

...

...

In the end, this is what blocks traefik from discovering other containers.

The content of the C:\ProgramData\Docker\config\daemon.json:

{
  "experimental": false,
  "hosts": [
    "npipe:////./pipe/docker_engine_windows"
  ]
}

I barely see the named pipe with the suffix _windows in any documentation or forum. I also reinstalled the entire OS + Docker, but it stays the same.

I post my container creation script and output as well just for the record.

We also recreate the traefik container each night. Since this image (1.7.34) is also 3 months old, I don't think it's the issue

I downgraded to v 4.0.7 of BcContainerHelper (not sure whether the issue appeared with .8 or .9) and recreated the container which didn't help. Then I recreated the traefik container and then recreated the container again, now everything seems to be working again.

In future to make it easier to find what got released in which version of bccontainerhelper it would be very helpful if you could add tags when you release a new version so it's easier to compare releases. I'm sorry I don't have time to look for what's actually going on but it must be a change between 4.0.7 and 4.0.9.

[freddydk]

Nothing has changed in this area for a very long time. @christianbraeunlich - I think you are right in the fact that your npipe is different - will investigate that. @itsme112358 - Are you running PowerShell as administrator?

[christianbraeunlich]

Look what I just found: https://www.axians-infoma.de/techblog/allow-access-to-the-docker-engine-without-admin-rights-on-windows - @tfenster also mentioned the docker_engine_windows. Maybe you'd like to share some insights? @itsme112358 can you check the content of the C:\ProgramData\Docker\config\daemon.json file. btw: love the git tag suggestion

[freddydk]

@christianbraeunlich - that code is built into Check-BcContainerHelperPermissions and will add permissions to this. This code has changed in 4.0.8 due to PS 7

[itsme112358]

@freddydk Thanks for the quick reply. Yes, everything is run via a Azure DevOps Agent which has local admin privileges. I also ran the scripts myself as admin, same results. And as mentioned, it now works, after going back to 4.0.7. I'm guessing it has to have something to do with the traefik container's configuration since it only worked after I recreated it (but also only after going back to 4.0.7; just recreating it, even rebooting did not solve it)

[tfenster]

Look what I just found: https://www.axians-infoma.de/techblog/allow-access-to-the-docker-engine-without-admin-rights-on-windows - @tfenster also mentioned the docker_engine_windows. Maybe you'd like to share some insights? @itsme112358 can you check the content of the C:\ProgramData\Docker\config\daemon.json file. btw: love the git tag suggestion

Do you run this with Docker Desktop? I think that is the only way how you can end up with a docker_engine_windows npipe

[freddydk]

@itsme112358 - I have moved your issue to a new issue - I don't think that is related to Docker Desktop and the original problem

[itsme112358]

You are correct, I didn't read the error message correctly, I just read that there was an issue with the named pipe, which it seemed to fit with my issue. Plus it fit the timing 🙈 Sorry about that! See you over there ;)

[freddydk]

@christianbraeunlich - is this still an issue?

[christianbraeunlich]

I've just checked in with the info on my working pc (win10) and the content of the deamon.json is also:

{
  "experimental": false,
  "hosts": [
    "npipe:////./pipe/docker_engine_windows"
  ]
}

So as Tobias pointed out, it might be the fact that I run Docker Desktop. Don't really know.. I created a workaround for myself by using the Docker Image from Tobias and create all containers with additional parameters, providing the docker labels that Traefik makes use of. So for me the script in this module still does not work, but it might be an edge case. So if anyone else might come up with similar problems in the future we can reference to this issue.
