How to pull layers one by one in Docker to avoid c

Question

I keep getting connection timeout while pulling an image:

First, it start downloading the 3 first layers, after one of them finished, the 4th layer try to start downloading. Now the problem is it won't start until the two reminded layers finish there download process, and before that happens (I think) the fourth layers fail to start downloading and abort the whole process. So I was thinking, if downloading the layers one by one would solve this problem. Or is there a way to download images manually with my browser?

Answer 1

Please follow the step if docker running already Ubuntu:

sudo service docker stop
sudo dockerd --max-concurrent-downloads 1

Download your images after that stop this terminal and start the daemon again as it was earlier.

sudo service docker start

Answer 2

The Docker daemon has a --max-concurrent-downloads option. According to the documentation, it sets the max concurrent downloads for each pull.

So you can start the daemon with dockerd --max-concurrent-downloads 1 to get the desired effect.

See the dockerd documentation for how to set daemon options on startup.
