This repository contains simple ingress example to have Istio configured with a kubernetes cluster deployed in IBM Cloud.
The default secret is created in the default namespace, and you can view it via kubectl get secret -n default. Copy it to the istio-system namespace:
kubectl get secret ${secret_name} -o yaml | sed 's/default/istio-system/g' | kubectl -n istio-system create -f -
Open the plans/frontdoor-ingress.yaml file and check if it is using the same region as your kubernetes cluster. The default being used is us-east. Change it to your region if needed, and deploy the plans/frontdoor-ingress.yaml:
cat frontdoor-ingress.yaml| sed 's/xxxx/${cluster_name}/g' | sed 's/ssss/${secret_name}/g' | kubectl -n istio-system create -f -
