Pulling images

Closed this issue · 1 comments

Swarm directly controls the pulling of images, but JupyterHub should wait around 60 secs after you return ip and port of the spawned server.

So when you pull images that are not already available locally you can get some time-out error.

I can't find a way to control the pull of images from docker with Swarm.
So the best way for now is to have the images on each node.
