Docker pulls from Docker Hub painfully slow


(Joeys) #1

Hi, I’m a newcomer to docker, until now I’ve been a Vagrant power-user where pulling boxes is a breeze, so this has been a bit surprising to me… It’s my first week with docker and trying to $ docker pull any image from the Hub, even official ones, is really slow, like 450Mb in 24h. The download speeds start ok, but the final layers are simply horrible.

I know this has been discussed several times, and I’ve done extensive research about the issue without luck in my attempts to fix it. I hope this is just a bug/misconfiguration on my end or somewhere, so I need some help debugging.

I’ve tried this script and it’s outdated. But I’ve tested and I’m able to wget any .iso image from that mirror with 5mbps average speeds being inside the boot2docker vm…

$ wget http://mirrors.sonic.net/centos/7/isos/x86_64/CentOS-7-x86_64-Everything-1503-01.iso

I’ve also tried to add: 54.224.119.89 cdn-registry-1.docker.io entry to /etc/hosts in the boot2docker vm (as suggested in a couple of related github issues). Still no luck.

For me, putting a private registry cache is not an option right now, it’s my first week with docker, I’m just evaluating the tool for my upcoming projects and I just expected a smooth devops experience interacting with the docker hub.

If you can shed a bit of light I’d be very grateful! Thanks!

I’m also getting this random error…

$ docker pull postgres
