When using the latest version of this library, I got this (https://travis-ci.org/Jiri-Kremser/spark-operator/builds/399085700#L2093 ( https://github.com/Jiri-Kremser/spark-operator/pull/48 )):

I use k8s-client in version 3.2.0 and trying to use k8s-model in 3.0.0 (no openshift-client in the picture). Am I missing something obvious here, or is it just a bug?

oscerd commented 6 years ago

The DaemonSet stuff in 3.0.0 will be in io.fabric8.kubernetes.api.model.apps.DaemonSet;

The client still need to be updated according to the new model, so you'll need to wait.

hey @Jiri-Kremser

DeamonSet has been moved to apps package from extension in openshift 3.9, we did the same thing in kubernetes-model 3.0.0 release. But client is expecting the same in extensions that is not any more avaialble. To fix this thing, I am already working on https://github.com/fabric8io/kubernetes-client/pull/1103 that will fix these errors in client. Hope this clears. Thanks

Closing the issue.

jkremser commented 6 years ago

cool, thanks for info. Perhaphs, it would be nice to release both mvn artifacts at the same time, because now it makes the k8s-model@3.0.0 unusable. I am not using the DeamonSets anywhere in my code, it just fails w/ this CNFE when initializing the client.

edit: i've just noticed this https://github.com/fabric8io/kubernetes-client/pull/1103#issuecomment-400350358 perhaps this can be handy for you: https://github.com/srcdeps/srcdeps-maven (it's also built by a Red Hatter :)) It can help if you want to test interactions between artifacts that haven't been released yet and you don't want to use SNAPSHOTs (because it's terrible for build reproducibility)

Thanks a lot, @Jiri-Kremser that is a good thing I was not aware of. Thanks a lot. Will use that further.

jkremser commented 6 years ago

just letting you know that model@3.0.0 with client@4.0.0 works well :+1:
