Annotations on binderhub pods

I was wondering if there was a way to add a k8s annotation on a binderhub pod that contains just the repo name? So far I’m able to add the annotation using extraConfig and KubeSpawner:

hub:
    extraConfig:
     myConfig: |
        c.KubeSpawner.extra_annotations= {
          "repo": '{username}'
        }

but this sets the annotation to the escaped pod name with the unique ID on it (I just want the repo name itself), I tried to manipulate the {username} string (striping the escape characters and unique ID) in the extraConfig too but it doesn’t seem to work…which I think is because the python code in extraConfig executes before the pod actually gets spawned?

yeah, currently we have ELK set up to send all binderhub notebook std out logs to a single index (and schema)…but I’m trying to explore if we can create a separate index per repo which would allow separate schemas

I didn’t realise we already passed the repo URL over the API. Nice. Then I think the place to make changes is https://github.com/jupyterhub/binderhub/blob/207ae704752cde82f33fc771a3b58aa1ecc04b6d/helm-chart/binderhub/values.yaml#L78 which is the spawner used by BinderHub. Together with maybe hooking into (or adding to) the _common_annotations method you linked.

Will you use elastic for logging?
