You will need to manually enable Istio in each namespace that you want to be tracked or controlled by Istio. When Istio is enabled in a namespace, the Envoy sidecar proxy will be automatically injected into all new workloads that are deployed in the namespace.
|
||||
|
||||
This namespace setting will only affect new workloads in the namespace. Any preexisting workloads will need to be re-deployed to leverage the sidecar auto injection.

The Istio overview page provides a link to the Kiali dashboard. From the Kiali dashboard, you can view graphs for each namespace. The Kiali graph provides a powerful way to visualize the topology of your Istio service mesh. It shows you which services communicate with each other.

The gateway to each cluster can have its own port or load balancer, which is unrelated to a service mesh. By default, each Rancher-provisioned cluster has one NGINX ingress controller allowing traffic into the cluster.
|
||||
|
||||
You can use the Nginx Ingress controller with or without Istio installed. If this is the only gateway to your cluster, Istio will be able to route traffic from service to service, but Istio will not be able to receive traffic from outside the cluster.

A central advantage of traffic management in Istio is that it allows dynamic request routing. Some common applications for dynamic request routing include canary deployments and blue/green deployments. The two key resources in Istio traffic management are *virtual services* and *destination rules*.
|
||||
|
||||
- [Virtual services](https://istio.io/docs/reference/config/networking/v1alpha3/virtual-service/) intercept and direct traffic to your Kubernetes services, allowing you to divide percentages of traffic from a request to different services. You can use them to define a set of routing rules to apply when a host is addressed.
