Error when creating any istio gateway: context deadline exceeded

Rob_Kenefeck · August 3, 2020, 2:22pm

Installing Istio using istioctl I spotted that 3 resource were not getting created correctly due to timeout. meshexpansion-gateway meshexpansion-vs-istiod and meshexpansion-dr-istiod, all with the same context deadline exceeded error. After uninstalling istio and removing the istio-system namespace the problem still occurs. When I tried to create a non istio-system gateway, that fails with the same error.

Extracted the resources to manually add them, and got the same error. Attempted using the v1beta1 api instead and still get the same error.

I’ve run it in --v=8 to extract the debug of what is happening, and replaced my master ip address just in case

I found some old topics similar to this but noting that related. Has anyone seen this and know how I might resolve?

Thanks to John, I was able to get to the bottom of this. The error message “context deadline exceeded” was a symptom of the validatingwebhookconfigurations blocking the resources from being created. I was able to work around that by running:

kubectl delete validatingwebhookconfigurations which removed the istiod-istio-system hook and when I applied my extracted resources they added successfully.

Troubleshooting the webhook using https://github.com/istio/istio/wiki/Troubleshooting-Istio#diagnostics pointed me to the GKE firewall rule that had magically reverted back to not allowing 15017. Once that was updated again, the straight istioctl install -f mysettings.yaml worked again successfully.
