Title: Istio Gateway Authors: Rahul Sharma; Avinash Singh Venue: Apress eBooks Year: 2019 Canonical: doi:10.1007/978-1-4842-5458-5_5 URL: https://doi.org/10.1007/978-1-4842-5458-5_5 Collector: openalex OA: false ABSTRACT In the previous chapter, we discussed Istio request routing. We showed how to configure a virtual service and deployment rules to interact with different versions of our application. Up to now, all our services have been deployed in the Kubernetes cluster. But in real-world scenarios, we need to interact with components outside the Kubernetes cluster. There are many applicable use cases. For example, applications running inside the cluster may interact with a database deployed outside the cluster. Similarly, there can be user applications deployed in the cluster. These applications will need to be accessed from the Internet. In this chapter, we will show how to configure the Istio gateway and service entry, which will enable us to fulfill the discussed behaviors.
