This section describes how to enable Istio and start using it in your projects.
|
|
|
|
If you use Istio for traffic management, you will need to allow external traffic to the cluster. In that case, you will need to follow all of the steps below.
|
|
|
|
## Prerequisites
|
|
|
|
This guide assumes you have already [installed Rancher,](../../../getting-started/installation-and-upgrade/installation-and-upgrade.md) and you have already [provisioned a separate Kubernetes cluster](../../new-user-guides/kubernetes-clusters-in-rancher-setup/kubernetes-clusters-in-rancher-setup.md) on which you will install Istio.
|
|
|
|
The nodes in your cluster must meet the [CPU and memory requirements.](../../../explanations/integrations-in-rancher/istio/cpu-and-memory-allocations.md)
|
|
|
|
The workloads and services that you want to be controlled by Istio must meet [Istio's requirements.](https://istio.io/docs/setup/additional-setup/requirements/)
|
|
|
|
## Install
|
|
|
|
> **Quick Setup** If you don't need external traffic to reach Istio, and you just want to set up Istio for monitoring and tracing traffic within the cluster, skip the steps for [setting up the Istio gateway](set-up-istio-gateway.md) and [setting up Istio's components for traffic management.](set-up-traffic-management.md)

|
1. [Enable Istio in all the namespaces where you want to use it.](enable-istio-in-namespace.md)
|
|
1. [Add deployments and services that have the Istio sidecar injected.](use-istio-sidecar.md)
|
|
1. [Set up the Istio gateway. ](set-up-istio-gateway.md)
|
|
1. [Set up Istio's components for traffic management.](set-up-traffic-management.md)
|
|
1. [Generate traffic and see Istio in action.](generate-and-view-traffic.md)
