Polling frequency when attempting to connect to notebook container #22

isuftin commented 7 years ago

Is there a flag to allow setting the polling frequency for JupyterHub's polling of a starting notebook container? It seems to be polling 5 to 10 times per second which floods the service logs and I assume puts a decent load on the Docker network.

Example of JupyterHub's service logs when a container is being started (but the image not yet downloaded from the registry):
