Docker Push to Docker.io hub hangs as "waiting" with no error or timeout

[insightindustry (Chris Modzelewski)]

I’m attempting to push an image to my private Docker Hub account using the docker push command.

In the past, this has worked just fine (even for previous versions of this image).

However, it is now hanging in perpetual “waiting” mode as shown in the screenshot below:

It would seem the daemon has frozen in this “Waiting” state for the past 10+ minutes, with no timeout or error message reported. This is a problem that has appeared in the past and then “magically” gone away later. This time, the problem has persisted for some time.

ETA: Here is my docker version info:

Client:
Version: 1.10.3
API version: 1.22
Go version: go1.5.3
Git commit: 20f81dd
Built: Thu Mar 10 21:49:11 2016
OS/Arch: windows/amd64

Server:
Version: 1.10.3
API version: 1.22
Go version: go1.5.3
Git commit: 20f81dd
Built: Thu Mar 10 21:49:11 2016
OS/Arch: linux/amd64

Two questions:

1. Is there some way for me to fix this problem so that the Docker Hub Registry is actually functional for my purposes?
2. Is it possible for the Docker daemon to throw some sort of error when this problem occurs, so that I’m able to capture it and apply the fix, as needed?

Thanks,
Chris

FYI: Restarting the docker-machine (VirtualBox) seems to have provided some progress. In particular, now the docker push command hangs on a particular layer: “Pushing 1.407 MB/12.14 MB” (see screenshot below):

All the best,
Chris

Do you have anything interesting in your docker.log file?

Run this and then do a docker push in another terminal:

$ docker-machine ssh default
$ tail -f /var/log/docker.log

[insightindustry (Chris Modzelewski)]

Here’s the initial output of the docker.log (prior to executing the new docker push):

And here’s the output following a new docker push:

time=“2016-04-14T04:20:15.989144961Z” level=debug msg="GET /v1.22/info"
time=“2016-04-14T04:20:16.027590659Z” level=debug msg="Calling POST /v1.22/image

time=“2016-04-14T04:20:16.915397226Z” level=debug msg=“Increasing token expirati

So as it stands, I can’t see anything weird jumping out to me other than the “Increasing token expiration to: 0 seconds” line.

ETA: I didn’t mention it before, but the behavior of the new docker push is identical to the previous one, hanging up on the same exact layer with Pushing 1.407 MB/12.14 MB.

All the best,
Chris

[programmerq (Jeff Anderson)]

Does this happen only when pushing this repository? What happens if you do a push to a blank one?

[insightindustry (Chris Modzelewski)]

In the past, these symptoms have cropped up intermittently when pushing to a blank repository as well.

Incidentally, yesterday after this problem appeared I also deleted the repository and pushed to newly-created private repo as well - all to no avail.

[learningstaircase (Andrew)]

I am having similar issue, it doesn’t happen all the time for me, but I get a list of different layers, all saying waiting, then no pushing. I just redo the build/push and it goes through, but no error is getting sent out for the fact it didn’t push.

[mabuzagu]

I am having similar issue. Push to public repo just hangs. I am on Windows 7. No luck with redo

[taisph]

I am seeing this as well. Ubuntu 16.04, docker 1.11.2, public repo. Seems random how far it gets before it hangs. Sometimes stops with an HTTP error 408.

Hi!

I’m having the issue with Docker 1.12.0 on Windows 10 (the latest Insider build).

Checked the logs—nothing interesting there:

Did anyone come up with any workaround yet?

The docker push just hangs and waits indefinitely. It never completes.

[gioppoluca (Luca Gioppo)]

Same problem here.
I’m on CentOS 7
Docker version 17.04.0-ce, build 4845c56

The push command just hangs there doing nothing, no progress no messages no clue.
Just this:
86c4534765bb: Pushing [==> ] 655.9kB/11.03MB
and waiting.
Is there any logs apart journal that does not says anything useful to look for?
Any known workaround?

[lrkirven]

Same issue here as well. I am on GNU/Linux. Push command just hangs with the following display:

62197bea5fec: Pushing [============================================> ] 343.3 MB/388.6 MB

Appreciate any help, advice or workaround.

How do you guys solve this problem at the end?

[boonzaai]

Had exactly the same problem. Restarting docker fixed it.

[nachmangeva]

Yep - restart of docker “fixed” it…

[simonmiller99]

I had this and it proved to be an incorrect specification of the nexus repo url in the noproxy variable in docker https-proxy.conf- I’d used a wildcard but it did not seem to evaluate it when pushing. Details here https://github.com/docker/distribution/issues/2147 at this post where he was kind enough to post a permanent solution
