Uninstall Travel Demo

Remove components in reverse order of installation: the Travel Demo application, Kiali, Istio, and (on Kind) the cluster itself.

Uninstall the Travel Demo

Delete the demo namespaces:

kubectl delete namespace travel-agency
kubectl delete namespace travel-portal
kubectl delete namespace travel-control

Alternatively, delete the manifests first (this removes any Istio resources created in those namespaces during the tutorial):

kubectl delete -f <(curl -L https://raw.githubusercontent.com/kiali/demos/master/travels/travel_agency.yaml) -n travel-agency --ignore-not-found
kubectl delete -f <(curl -L https://raw.githubusercontent.com/kiali/demos/master/travels/travel_portal.yaml) -n travel-portal --ignore-not-found
kubectl delete -f <(curl -L https://raw.githubusercontent.com/kiali/demos/master/travels/travel_control.yaml) -n travel-control --ignore-not-found

kubectl delete namespace travel-agency
kubectl delete namespace travel-portal
kubectl delete namespace travel-control

./hack/istio/install-travel-agency-demo.sh -c oc -d true

Uninstall Kiali

Kind

helm uninstall --namespace istio-system kiali-server

OpenShift

Delete the Kiali CR first so the operator removes the Kiali server:

kubectl delete kiali kiali -n istio-system

Then uninstall the operator:

helm uninstall --namespace kiali-operator kiali-operator
kubectl delete crd kialis.kiali.io

If you installed the operator from OperatorHub, uninstall it from the OpenShift console using the same mechanism you used to install it.

Uninstall Istio

Kind

From the Kiali source repository:

./hack/istio/install-istio-via-istioctl.sh -c kubectl -di true

OpenShift

./hack/istio/install-istio-via-istioctl.sh -c oc -di true

Or use istioctl uninstall --purge -y and delete the istio-system namespace.

Delete the Kind cluster

If you created the cluster with hack/start-kind.sh, delete it when you are finished:

kind delete cluster --name travels-tutorial

This removes the Kind cluster and all resources running on it.
