Kubernetes Tasks only work with k8s 1.13, 1.14, 1.15

[gaby]

Description

The official kubernetes python client only supports up to k8s 1.15. As stated on their github page.

Compatibility matrix

	Kubernetes 1.13	Kubernetes 1.14	Kubernetes 1.15
client-python 9.0	✓	+-	+-
client-python 10.0	+-	✓	+-
client-python 11.0	+-	+-	✓
client-python HEAD	+-	+-	+-

k8s 1.15 is EOL and k8s 1.16 will be EOL in 10-2020.

See: https://github.com/kubernetes/sig-release/blob/master/releases/patch-releases.md

This issue is for tracking the release of Python Kubernetes Client 12.0.0 which will support k8s 1.16 and others.

Behavior

Currently if you try to deploy with CreateNamespacedDeployment Task or any kind of k8s Task, you will get a 404 error from the Kubernetes API due to the fact that both ExtensionsV1beta1Api and AppsV1beta1Api are deprecated in Kubernetes 1.16 and forward.

Thanks for opening @gabrielcalderon! I'm going to have to pull 12.0.0a1 and give it a test. I need to look further but I'm guessing that AppsV1Api will be the one to use

[gaby]

@joshmeek I was able to list my deployments using k8s client directly with AppsV1Api

@joshmeek They are about to merge version 12.0 :-)

[joshmeek]

@gabrielcalderon Awesome! Do you want to update the tasks to no longer use the beta clients?

[gaby]

@joshmeek Sure, I can take a look during the weekend. They just did the official release.
