Restart the cluster (virtual machine) istio-ingressgateway cannot start?

The error message is as follows:

Possible cause: The jwtsUri address of the RequestAuthentication CR cannot be accessed, As a result, istiod cannot deliver configuration to istio-ingressgateway (Istio 1.15 can avoid this bug: https://github.com/istio/istio/pull/39341/)

Solution:

  1. Back up the RequestAuthentication ghippo CR.

    kubectl get RequestAuthentication ghippo -n istio-system -o yaml > ghippo-ra.yaml

  2. Delete the RequestAuthentication ghippo CR.

    kubectl delete RequestAuthentication ghippo -n istio-system

  3. Restart Istio.

    kubectl rollout restart deploy/istiod -n istio-system
kubectl rollout restart deploy/istio-ingressgateway -n istio-system

  4. Re-apply RequestAuthentication ghippo CR.

    kubectl apply -f ghippo-ra.yaml

    Note

    Before applying RequestAuthentication ghippo CR, please make sure that ghippo-apiserver and ghippo-keycloak have been started normally.
