Document using a custom registry
Should include:
- [ ] Starting up a registry - https://docs.docker.com/registry/
- [ ] Use that registry in image in func.yaml?
- [ ] Pushing function to that registry
- [ ] Use that registry when creating route
This is more than just a documentation issue no?
Looking at the FIXME at the bottom of
https://github.com/iron-io/functions/blob/master/api/runner/task.go
It seems like there has been an admirable effort to avoid a giant bag of global configuration - but this is a case where you would need something analogous to the gitconfig byHost entries - so that from a fully qualified image path - you could reference globally configured credentials per registry.
Is the stop-gap to have a AppCreateListener watch for route additions and pre-fetch the image using a custom docker client?
Also will be good to consider how credentials can be registered as hooks at runtime so that registries using short term credentials can be dynamic:
