If you have restrictive Pod Security Policies enabled, then Istio may not be able to function correctly, because it needs certain permissions in order to install itself and manage pod infrastructure. In this section, we will configure a cluster with PSPs enabled for an Istio install, and also set up the Istio CNI plugin.
|
||||
|
||||
The Istio CNI plugin removes the need for each application pod to have a privileged `NET_ADMIN` container. For further information, see the [Istio CNI Plugin docs](https://istio.io/docs/setup/additional-setup/cni). Please note that the [Istio CNI Plugin is in alpha](https://istio.io/about/feature-stages/).

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.

If you have restrictive Pod Security Policies enabled, then Istio may not be able to function correctly, because it needs certain permissions in order to install itself and manage pod infrastructure. In this section, we will configure a cluster with PSPs enabled for an Istio install, and also set up the Istio CNI plugin.
|
||||
|
||||
The Istio CNI plugin removes the need for each application pod to have a privileged `NET_ADMIN` container. For further information, see the [Istio CNI Plugin docs](https://istio.io/docs/setup/additional-setup/cni). Please note that the [Istio CNI Plugin is in alpha](https://istio.io/about/feature-stages/).
