This FAQ is a work in progress designed to answer the questions most frequently asked about Rancher v2.x.
See the [Technical FAQ](technical-items.md) for frequently asked technical questions.
## Is it possible to manage Azure Kubernetes Services with Rancher v2.x?
Yes. See our [Cluster Administration](../how-to-guides/new-user-guides/manage-clusters/manage-clusters.md) guide for what Rancher features are available on AKS, as well as our [documentation on AKS](../getting-started/installation-and-upgrade/install-upgrade-on-a-kubernetes-cluster/rancher-on-aks.md).
## Does Rancher support Windows?
Yes. Rancher supports Windows Server 1809 containers. For details on how to set up a cluster with Windows worker nodes, refer to the section on [configuring custom clusters for Windows.](../how-to-guides/new-user-guides/kubernetes-clusters-in-rancher-setup/use-windows-clusters/use-windows-clusters.md)
## Does Rancher support Istio?
Yes. Rancher supports [Istio](../integrations-in-rancher/istio/istio.md).
## Will Rancher v2.x support Hashicorp's Vault for storing secrets?
As of Rancher v2.9, Rancher [supports authentication with service account tokens](../how-to-guides/new-user-guides/authentication-permissions-and-global-configuration/jwt-authentication.md), which is used by Vault and other integrations.
## Does Rancher v2.x support RKT containers as well?
At this time, we only support Docker.
## Does Rancher v2.x support Calico, Contiv, Contrail, Flannel, Weave net, etc., for embedded and registered Kubernetes?
Out-of-the-box, Rancher provides the following CNI network providers for Kubernetes clusters: Canal, Flannel, Calico and Weave. Always refer to the [Rancher Support Matrix](https://rancher.com/support-maintenance-terms/) for details about what is officially supported.
## Are you planning on supporting Traefik for existing setups?
We don't currently plan on providing embedded Traefik support, but we're still exploring load-balancing approaches.
## Can I import OpenShift Kubernetes clusters into v2.x?
Our goal is to run any Kubernetes clusters. Therefore, Rancher v2.x should work with OpenShift, but we haven't tested it yet.
## Is Longhorn integrated with Rancher?
Yes. Longhorn is integrated with Rancher v2.5 and later.
