The Service Mesh Bookinfo sample application consists of four separate microservices, each with multiple versions. After installing the Bookinfo sample application, three different versions of the
reviews microservice run concurrently.
When you access the Bookinfo app
/product page in a browser and refresh several times, sometimes the book review output contains star ratings and other times it does not. Without an explicit default service version to route to, Service Mesh routes requests to all available versions one after the other.
This tutorial helps you apply rules that route all traffic to
v1 (version 1) of the microservices. Later, you can apply a rule to route traffic based on the value of an HTTP request header.
