Eureka - How do I unset the context changed by `istioctl` at the end?	70

Your kubectl is switched to use the istio context at the end of the istio context-create command. You can use kubectl config get-contexts to obtain the list of contexts and kubectl config use-context {desired-context} to switch to use your desired context.
