dkleissa · 2020-11-03T16:46:28Z

An interesting observation on various version. I'm seeing this same issue on:

latest Docker Desktop for Mac stable channel (2.5.0.0)
latest Docker Desktop for Windows edge channel (2.4.2.0) on HyperV

I do not see this issue on:

latest Docker Desktop for Windows stable channel (2.5.0.0) on WSL2
latest Docker Desktop for Windows stable channel (2.5.0.0) on HyperV

dkleissa · 2020-11-03T19:11:31Z

We use this pattern to check if a container exists already before starting a container or when fetching the status of a container, as our software uses deterministic container names. In the case where the container isn't running we catch docker.errors.NotFound, which is now broken as @mconcas points out. After initial testing, it does appear this is the only place in the API that is broken like this.

A very temporary fix is catching the unexpected error, again this is unexpected, fragile, and possibly not useful for everyone's use case:

import docker

client = docker.from_env()
try:
    client.containers.get("<non-existent-container-name>")
except docker.errors.NotFound:
    pass
except requests.exceptions.ChunkedEncodingError:
    pass

avirshup · 2020-11-10T01:06:08Z

Same issue - I was able to downgrade to 2.4 (link) to get it working again, no factory reset necessary.

yannickperrenet · 2020-11-10T12:59:51Z

They have just released version 2.5.0.1 which states to have fixed another Mac related issue (as you can see here in their docs). Not sure whether that also fixes this issue (which I sadly cannot test as I do not have a Mac), but I figured it was worth mentioning.

reynoldsdj · 2020-11-10T13:35:01Z

Docker 2.5.0.1 does not fix this issue on the mac. I upgraded to 2.5.0.1 and tested it. 2.5.0.1 fixes an issue with Big Sur and Virtualbox.

jukkei · 2020-11-10T13:40:29Z

Will test it soon. Somehow new docker-desktop downgraded kubernetes to 1.16.6-beta.0 from 1.19.3 (by using kubectl get nodes), but that's not related to this issue.

ch3ck · 2020-11-12T23:13:09Z

This issue is affecting our container builds, I don't know if there's a release coming out soon to fix this.

mconcas · 2020-11-13T11:20:09Z

As a side note: the CI does not catch the problem because the default docker version in Travis is still 18.x ...
This will be true even if they update from xenial to bionic and will require further action on the CI config.
Moreover I could not find the unit test that checks for this.

fixes docker/docker-py#2696 by catching exceptions.

thaJeztah · 2020-11-18T11:56:05Z

I think this may be the same issue as docker/for-mac#5025 / docker/for-mac#5058 / docker/for-mac#5059. More details can be found in this comment: docker/for-mac#5059 (comment)

thaJeztah · 2020-11-18T11:58:13Z

If the python code you're running is running on the mac itself, I'm not sure if there's a workaround, but if the code is running inside a container, you can (as a workaround) bind-mount /var/run/docker.sock.raw instead of /var/run/docker.sock to skip the docker desktop API proxy

thaJeztah · 2020-11-18T12:07:02Z

Oh, actually, there might be a workaround; the "raw" socket is also available on the mac side in;

$ ls -la ~/Library/Containers/com.docker.docker/Data/docker.raw.sock

srwxr-xr-x   1 sebastiaan  staff         0 Nov 16 11:24 docker.raw.sock=

e.g.;

$ docker -H unix:///Users/sebastiaan/Library/Containers/com.docker.docker/Data/docker.raw.sock version
Client: Docker Engine - Community
 Version:           20.10.0-beta1
 API version:       1.41
 Go version:        go1.13.15
 Git commit:        ac365d7
 Built:             Tue Oct 13 18:13:53 2020
 OS/Arch:           darwin/amd64
 Context:           default
 Experimental:      true
...

⚠️ ⚠️ BIG FAT WARNING!!! ⚠️ ⚠️

I think the name of that socket will be renamed soon, so only use this as a temporary workaround.
Also, when "skipping" the API proxy, some things may not work as expected (for example, paths
used in bind-mounts are not rewritten, network settings may not be adapted for how Docker Desktop is setup)

☝️ ☝️ ☝️ ☝️ IOW: the recommended socket to use will be /var/run/docker.sock, which is the official API to connect (for reasons above).

reynoldsdj · 2020-11-18T14:54:59Z

I think this may be the same issue as docker/for-mac#5025 / docker/for-mac#5058 / docker/for-mac#5059. More details can be found in this comment: docker/for-mac#5059 (comment)

Yes, I believe that it the exact cause of this issue. docker/for-mac#5025

thaJeztah · 2020-11-18T17:49:02Z

looks like the issue should be fixed in the latest edge release that was just published docker/for-mac#5025 (comment)

kilrau · 2020-11-20T13:11:54Z

Latest edge doesn't fix this for me. Can someone confirm?

reynoldsdj · 2020-11-20T13:45:32Z

I concur. I just upgraded, and I am seeing the same error.

reynoldsdj · 2020-11-20T13:56:31Z

thaJeztah · 2020-11-20T14:24:12Z

Can confirm that I still see the problem;

Incorrect response with the proxied socket;

@thaJeztah I'm trying to migrate from 2.3.2 to higher, we are uing docker stack like:

volumes:
   /var/run/docker.sock.raw:/var/run/docker.sock

Is there a way not to add ".raw", cause it is not backward compatible and will fail for those who stay on 2.3.2 (we have way to many non programmer users who will not know what to do with this)

milas · 2022-07-28T22:20:12Z

This is fixed in current versions of Docker Desktop.

Initially created in #22250 Both original issues are already solved for over 2.5 years: - docker/for-mac#5025 - docker/docker-py#2696 This will also allow anyone to use Orbstack without any modifications.
