How to fix Docker's “Error pulling image…too m

Question

I am running Docker via CoreOS and Vagrant on OS X 10.10.

When I run docker pull ubuntu in CoreOS, I got following errors:

$ docker pull ubuntu

I'd really appreciate if anyone could give me a useful advise on how to troubleshoot this problem.

Answer 1

On MacOSX, if you use Docker Machine you can try to:

 docker-machine ls
 docker-machine ssh YOUR_VM_NAME

and then from within the VM: kill the /usr/local/bin/docker process and start it again by hand:

 sudo /usr/local/bin/docker -d -D -g /var/lib/docker -H unix:// -H tcp://0.0.0.0:2376 --label provider=virtualbox --tlsverify --tlscacert=/var/lib/boot2docker/ca.pem --tlscert=/var/lib/boot2docker/server.pem --tlskey=/var/lib/boot2docker/server-key.pem -s aufs

Funnily enough, restarting like this

sudo /etc/init.d/docker restart

does not help.

Answer 2

10.0.2.3 is virtualbox dns server, check Fine-tuning the VirtualBox NAT engine

You can as other suggested use 8.8.8.8 which is google dns server.

# /etc/resolve.conf
nameserver 8.8.8.8

And if you work in intranet, then replace it with your normal dns server, which you can add search as well like below

# /etc/resolve.conf
nameserver xxx.xxxx.xxx
search company.com

This will be good to access your private repo

Answer 3

On windows I was able to fix it by doing the following:

1. Go to virtual box application
2. Delete the VM that was created
3. Restart computer (optional, i think)
4. Start Kitematic
5. Go back to Virtual Box, hit show
6. Make sure ping google.com command works

Now I am able to download docker images from the hub.

Answer 4

Try this temporary workaround:

osx$ boot2docker up
osx$ boot2docker ssh
docker@boot2docker$ sudo echo "nameserver 8.8.8.8" > /etc/resolv.conf
docker@boot2docker$ sudo /etc/init.d/docker restart

It works until reboot.

Answer 5

I had a similar issue when trying to pull a container from docker repository with this command :
docker pull ubuntu

Note that I was using coreos inside virtualbox and I was using Nat as my Networking Configuration to have access to internet. When Switching network modes with virtualbox, I couldn't do any pull.

I solved the issue by restarting docker with systemctl by iniating this command :
sudo systemctl restart docker

And then my pull worked fine. I hope this solution helped you. And I got it from from google group issue addressed by one of CoreOS creators(Brandon Philips) through this link: https://groups.google.com/forum/#!topic/coreos-dev/vWqSbPgNYro

Answer 6

I don't know about OS X, but on linux this could happen due to "bad" /etc/resolv.conf on the host. For example, ubuntu puts something like:

nameserver 127.0.1.1

and then handles the DNS requests through some service. The problem is, that this is accessible from inside of the image.

To fix this, I had to add some external nameservers, like:

nameserver 127.0.1.1
nameserver 8.8.8.8
nameserver 8.8.4.4
