I'm getting this message

Does the data field need to be json encoded before passing to Kazan functions for configmap?
Please help :)
@mayppong I've been able to submit a configmap without json encoding the data field:
%Core.ConfigMap{
data: %{test: "something"},
metadata: %ObjectMeta{generate_name: "test"}
}

}
Is kazan updated for v1.10 of the k8s api?
I'm trying out kazan for the first time and I'm having an auth issue. I'm using
The error is a
.from_kubeconfig() which generates a Kazan.Server{} where auth: nil (not sure if that's relevant). I'm using gcloud sdk to configure kubectl.The error is a
403 "unknown user 'system:anonymous'". Any thoughts on what I might be doing wrong?
@znorris is this with GKE? The master branch doesn’t currently support the auth method that gcloud uses for GKE. There is an in progress PR to add this though, so you could use that fork in the meantime: obmarg/kazan#48
Though think I’m going to put aside some time to finish that PR today
Though let me know if you still run into problems, I don’t have access to a GKE cluster to test with
@obmarg I think there's something wrong but I'm really just getting started in Elixir. After using
.resolve_auth I get a struct with the token. But I'm not matching this case https://github.com/obmarg/kazan/blob/master/lib/kazan/client/imp.ex#L40
Instead I get the case below it, "Provider authentication needs ..."
Hi,
i would like use your lib but i dont understand one thing in Kazan.Watcher part.
Start a watcher using the request, and passing the initial resource version and a pid to which to send received messages.
Kazan.Watcher.start_link(request, resource_version: rv, send_to: self())
...
resource_version - The version from which to start watching.I don't understand what is resource version ?
Do you have a example of an watcher ?
For example if you got on a pod while it was at resource version 1, then changed that pod and did a watch with resource version 1, you should see an event for your change come through
It’s intended to make sure you don’t miss changes on resources that are changing frequently
If you don’t have a resource version it’s ok to leave that off and Kazan will figure it out for you
A lot easier to diagnose when I can see what’s going on 🙂
thks a lot :)
Ok, so a watcher that’s started with send_to: self will send messages to the current process. You’ve added a handle_info function, but handle_info only gets sent messages when it’s part of a GenServer. If you wanted to receive messages outside of a GenServer you could use a receive block instead
So yeah, either make it a GenServer or add a receive block to handle the watcher messages
like this ?
Give me a minute
I'm afraid I don't have a GenServer example of using watcher to hand, and don't have enough time to put something together right now
but i can share this non-gen server example: https://gist.github.com/obmarg/c31d91b61a0ef8aff4f0428f7412d3a4
(though one gotcha : that example is using kazan 0.9, and a few things have changed in 0.10)
actually, seems I do have time to throw something together right now: https://gist.github.com/obmarg/1f25161cd72d219e906c6befbe23e0f0
that's roughly what you'd want for a GenServer - haven't tested it mind you
