mybinder.org usage

[betatim]

Hello from mybinder.org :) Just wanted to stop by and say that I like nbinteract!

You are by far the biggest user of mybinder.org by number of pods launched. Once in a while we will get about ~350 or so pods related to nbinteract appear all in oen go and then slowly die away again over time. I was wondering if you knew what that could be.

This is what it looks like on grafana.mybinder.org

It looks like nbinteract is also used for https://www.textbook.ds100.org/ and makes a request to mybinder.org each time someone loads the page. This means each visitor spawns a new binder. As far as I can tell that binder is re-used for that visitor. Right now there are 221 pods related to the ds100 textbook running. Could you adjust nbinteract so that it only makes a request when the user explicitly clicks a button to make the page interactive?

Right now the nbinteract behaviour leads to us having to scale up the mybinder cluster a lot (which costs $$$) and presumably most of the nbinteract related binders are just idling. So requiring a click would be good to keep the load lower.

And we will soon limit the number of concurrent users for a given repo, so this will probably start failing to get Binders if it's requesting more than it needs.

Related mybinder issue jupyterhub/mybinder.org-user-guide#34. Maybe close this?
