`docker pull` can't resume when killed with spotty internet

(Cole Mickens) #1

Expected behavior

docker pull can be ctrl-cd and executed again and docker daemon will continue where it left off.

Actual behavior

I’m on Gogo right now (it’s slow and spotty). I try to pull an image. It gets some percentage of the way done and then just stops. If I kill the docker pull invocation and then try to run it again, it picks up where it left off but it never proceeds further than where I killed it. I have to actually restart Docker in macOS (aka the VM) before it will pull anything. Of course, that starts the layer over, so I’m basically unable to ever get the layer (until I land at least).

Steps to reproduce the behavior

  1. Start a docker image pull with fairly slow/spotty internet.
  2. Wait until the download stalls and stops (even though other Internet works).
  3. Ctrl-c the docker pull
  4. Start the docker pull again
  5. Notice that it doesn’t ever proceed past where it was when you killed it.


It’d be nice if I could open the forums without clobbering my clipboard (re: “Copy diag id to clipboard and open forum” button). Plus this template doesn’t even ask for the Diagnostics ID.

And my Diagnostic ID is 8337D04F-39A8-42F9-83C3-994544794087.

the interrupted download can never seem to be able to go past the 412MB mark.

I think I’m going to stop using docker because of this.
This is not logical at all having to re download a 2GB docker image every time.

(Nick Reilingh) #4

+1 from me, but I’m actually using Docker for Windows inside a VMware Fusion on a Mac. I don’t know if that’s what’s causing the spotty connection (I get the same thing happening whether I’m using bridged or NAT networking), or if my host machine would have the same problem. Since I’m trying to download a windows container, I can’t actually use a docker pull on the image from the mac side, so right now I’ve spun up an AWS EC2 instance for the sole purpose of pulling this image, doing a docker save to a tar file, and then transferring it to my VM through other means.

Just to be clear, the behavior we are seeing is that any fully loaded fs layers are not re-downloaded, but if a layer stalls and is cancelled, it will ALWAYS restart from the beginning instead of resuming where it left off. I can usually download between 20-100 MB at a time successfully, but this windows layer is 4GB so I’m just never getting anywhere close.
