Docker don't download images


(Digrouz) #1

Hi,

I’m trying docker for the first time, and i’m having issues downloading docker images from internet. If I try with the “hello-world” image, it don’t find it locally and never downloads it, it get stucks until I control-c it.
# docker run hello-world Unable to find image 'hello-world:latest' locally

Can someone help me to fix this?

My server is deban jessie with all the updates and the backported kernel 4.5, all of that running on top of zfs. My docker version is:

I just found that setting back my mtu from 9000 to 1500 solved the issue. Is it normal? is docker incomptible with jumbo frames ?
