When the Rancher server is deployed in the Docker container, a local Kubernetes cluster is installed within the container for Rancher to use. Because many features of Rancher run as deployments, and privileged mode is required to run containers within containers, you will need to install Rancher with the `--privileged` option.

### FAQ
<br>
<br/>
Q. Do I have to upgrade Rancher to get Rancher’s support of the upstream Dockershim?
Q. Do I have to upgrade Rancher to get Rancher’s support of the upstream Dockershim?
A The upstream support of Dockershim begins for RKE in Kubernetes 1.21. You will need to be on a version of Rancher that supports RKE 1.21. See our support matrix for details.

<br/>
Q. I am currently on RKE with Kubernetes 1.20. Do I need to upgrade to RKE with Kubernetes 1.21 sooner to avoid being out of support for Dockershim?
Q. I am currently on RKE with Kubernetes 1.20. Do I need to upgrade to RKE with Kubernetes 1.21 sooner to avoid being out of support for Dockershim?
A. The version of Dockershim in RKE with Kubernetes 1.20 will continue to work and it is not deprecated until a later release. For information on the timeline, see the [Kubernetes Dockershim Deprecation FAQ](https://kubernetes.io/blog/2020/12/02/dockershim-faq/#when-will-dockershim-be-removed). It will only emit a warning of its future deprecation, which Rancher has mitigated in RKE with Kubernetes 1.21. You can plan your upgrade to 1.21 as you would normally.

Q: What are my other options if I don’t want to depend on the Dockershim?
Q: What are my other options if I don’t want to depend on the Dockershim?
A: You can use a runtime like containerd with Kubernetes that does not require Dockershim support. RKE2 or K3s are two options for doing this.

Q: If I am already using RKE1 and want to switch to RKE2, what are my migration options?
Q: If I am already using RKE1 and want to switch to RKE2, what are my migration options?
A: Today, you can stand up a new cluster and migrate workloads to a new RKE2 cluster that uses containerd. Rancher is exploring the possibility of an in-place upgrade path.
