@ethanscho Can you check logs from the Katib-ui pod and Katib-ui image version, please?
Also, is status of Katib-ui pod Running?

[anupash147]

Same is the case for me, just that I have installed kubeflow version 1.0.0. All my katib deployments are working

The katib ui image am running is gcr.io/kubeflow-images-public/katib/v1alpha3/katib-ui:v0.8.0.

One another thing, i have a dex based istio deployment

@anupash147 Are you using this config: https://github.com/kubeflow/manifests/blob/master/kfdef/kfctl_istio_dex.v1.0.0.yaml ?

I also am seeing the same thing (kubeflow v1.0.0 and this config https://github.com/kubeflow/manifests/blob/master/kfdef/kfctl_k8s_istio.yaml). I can port forward the service via kubectl port-forward svc/katib-ui -n kubeflow 8080:80 but nothing shows up for me either thru the central dashboard. The other components like pipelines/jupyter/artifacts are viewable, just not katib

[andreyvelich]

@terrykong Is your katib-ui pod Running?
Also, can you open console in your browser and check if you have any errors there?

[terrykong]

hey @andreyvelich

the katib-ui pod is running, but i don't see any errors when i tail the log while i try to open the UI from the central-dashboard

[anupash147]

@andreyvelich yes I am using kfctl_istio_dex.v1.0.0.yaml, Also for me when i port-forward, i can see the katib-ui just not in the dashboard.

[andreyvelich]

@terrykong @anupash147 Can you check any errors in the browser console, while opening Katib UI from the Central Dashboard?

[terrykong]

@andreyvelich this morning i tried to get to the katib UI from the central dashboard and it miraculously showed up. wished it didn't just go away on its own 😞 . if it disappears again i'll update.

[terrykong]

fwiw, even though the katib ui showed up i see a Failed to retrieve GKE metadata TypeError: Failed to fetch error in the console. not relevant to me I'm guessing since i'm not running my cluster on GKE

[andreyvelich]

@terrykong Did you access central dashboard using port-forward? And where you run your k8s cluster? Sometimes it can lose connection between Kubeflow components. Updating the page should help with it.

[terrykong]

@andreyvelich i've always accessed the central dashboard through the istio ingressgateway

i'm running an on-prem cluster.

[andreyvelich]

@terrykong I think sometimes you should refresh the page to see Katib UI in the Central Dashboard.
Next time you can't access Katib UI, please, show me the errors from the browser console.

It working for me too ..
