## Istio Sidecar Auto Injection
In the create and edit namespace page, you can enable or disable [Istio sidecar auto injection](https://istio.io/blog/2019/data-plane-setup/#automatic-injection). When you enable it, Rancher will add `istio-injection=enabled` label to the namespace automatically.
After the `istio-injection=enabled` label is added to the namespace, all pods that are created in the namespace will have an injected Istio sidecar.
> **Note:** Injection occurs at pod creation time. If the pod has been created before you enable auto injection. You need to kill the running pod and verify a new pod is created with the injected sidecar.
