@Jeffwan Can't we update it to a later version?

[Jeffwan]

Yes. EKS supports up to 1.22 at this moment. However, seems we are still using 1.19 libraries and it may brings compatibility issue?

training-operator/go.mod

Lines 14 to 17 in ce82602

	k8s.io/api v0.19.9
	k8s.io/apimachinery v0.19.9
	k8s.io/client-go v0.19.9
	k8s.io/code-generator v0.19.9

I would suggest to bump the version once we upgrade libraries.

@johnugeorge @Jeffwan
If we want to use K8s v1.22, we should upgrade eksctl version in AWS CI worker image.

em. Seems all jobs failed and I suspect it could be the problem of ksonnet. If ksonnet can not support 1.19, then it brings additional work..

[johnugeorge]

@Jeffwan Can you please take a look to temporarily fix CI?
