Based on the Kubeflow 1.8 release timeline, 1.8 is planned to be released in early Oct.

Kubernetes

• Kubernetes 1.25 is EOL 2023-10-28
• Kubernetes 1.26 is EOL 2024-02-28
• Kubernetes 1.27 is EOL 2024-06-28
• Latest version of Kubernetes will be 1.28, planned to be released on August 15th, 2023, which is during Kubeflow 1.8 manifest testing phase

GKE - pipeline CI/CD

• GKE release schedule
  • Stable version
    • 1.26 will be ready 2023-06
    • 1.27 will be ready 2024-Q1

Other WG uses minikube and KinD, which already support all Kubernetes versions.

Taking all these into account, I think we should aim for k8s 1.27, assuming that Kubeflow 1.9 will not be released by EOL for k8s 1.26

Agree to the idea aiming at 1.27. Can we support 1.25 as the the minimum version for supporting existing deployments and their upgrades?

[DnPlas]

Distribution owners, I would like to confirm with you these versions are okay. Please comment on this issue if you agree/disagree or have suggestions.

After discussing the K8S versions with @kimwnasptd @NohaIhab, we decided to go with v1.25 and 1.26 since some of the components are incompatible with K8S 1.27, that is the case for istio 1.17 and cert-manager 1.12.

This will also help with the upgrade story from 1.7 to 1.8 cc @johnugeorge

I think we need to fork https://github.com/arrikto/oidc-authservice and use version arrikto/oidc-authservice@0c4ea9a

Closing this issue as we have agreed on the versions for the release. No further action is required.

[gptbert]

When will kubeflow support k8s 1.28?

[kabilan6]

Any plans for K8s 1.28 support before next ajor kubeflow release ?

[juliusvonkohout]

Honestly just try out Kubeflow 1.8 with Kubernetes 1.28 and report back here. It might just work.

[hume-brian]

@juliusvonkohout any luck with kubeflow 1.8 on k8s 1.28?

[juliusvonkohout]

@hume-brian 1.8.1 runs on Kubernetes 1.27-1.29. Although officially only 1.27
