https://github.com/jupyterhub/kubespawner/blob/master/kubespawner/spawner.py#L1898 is probably the place to look. We are creating a PVC before starting the pod if needed, so we can attach the PVC to the pod. Same way, we...

I like https://github.com/binder-examples/rocker as a pattern we can emulate. @choldgraf does, say, neurodebian already have a set of docker images it maintains? If so we can maybe work to add...

I personally love what @craig-willis is doing with `RockerBuildPack`, and think *extensions* to repo2docker is the way forward. My blocking concern with making it configurable from *inside* repo2docker is this...

@betatim: > Question (after a quick browse of your code @yuvipanda): My impression is that you implement what I wrote in my TL;DR except for using entrypoints. Instead you insert...

@betatim > Doesn't your prototype already let creators of repos choose the base image via what they write in n`pangeo-stack`? Nope it does not. It constrains them to *only* choosing...

> TL;DR Right now I am in favour of "build packs choose their base image", "build packs decide which stack they are in" and "use entrypoints to allow external packages...

https://github.com/yuvipanda/pangeo-stack-onbuild is the other prototype, where stack authors make -onbuild variants of their images. This lets users directly specify which (supported) image they wanna use, and empowers stack authors to...

https://mybinder.org/v2/gh/yuvipanda/pangeo-stack-onbuild/master works! It is based off the base-notebook image from PANGEO stack, but lets users customize it simply with an environment.yml file in the repo directory. It also works with...
