+# k0s Conformance
+
+## k0s - Zero Friction Kubernetes
+
+Full instructions on how to set up a k0s cluster can be found [here](https://github.com/k0sproject/k0s/blob/main/docs/create-cluster.md).
+
+## Requirements
+
+k0s runs either as a single node (controller with `--enable-worker`), or as a controller/worker cluster.
+These instructions assume you have one or more linux or arm boxes ready for installation.
+
+Download the k0s v1.27.1+k0s.0 binary from [releases](https://github.com/k0sproject/k0s/releases/tag/v1.27.1%2Bk0s.0) and push it to all the nodes you wish to connect to the cluster.
+
+## Cluster Setup
+
+#### Single node
+
+```
+$ k0s controller --enable-worker
+```
+
+#### Multiple nodes
+
+##### Controller
+
+```
+$ k0s controller
+```
+
+Once k0s on the controller is up, create a join token
+
+```
+$ k0s token create --role=worker
+```
+
+##### Joining Workers To The Cluster
+
+```
+$ k0s worker "long-join-token"
+```
+
+## Run the Conformance Test
+
+To run the conformance test, download a [binary release](https://github.com/vmware-tanzu/sonobuoy/releases) of sonobuoy, or build it yourself by running:
+
+```
+$ go get -u -v github.com/vmware-tanzu/sonobuoy
+```
+
+Deploy a Sonobuoy pod to your cluster with:
+
+```
+$ export KUBECONFIG=/var/lib/k0s/pki/admin.conf
+$ sonobuoy run --mode=certified-conformance --kube-conformance-image-version=v1.26.0
+```
+
+The test will take more than an hour to complete, but you can follow the logs by running:
+
+```
+$ sonobuoy logs -f
+```
+
+To view actively running pods:
+
+```
+$ sonobuoy status
+```
+
+Example:
+
+```
+root@controller-0:~# sonobuoy status
+         PLUGIN     STATUS   RESULT   COUNT
+            e2e   complete   passed       1
+   systemd-logs   complete   passed       3
+
+Sonobuoy has completed. Use `sonobuoy retrieve` to get results.
+```
+
+Once the tests complete, retrieve the results file by running:
+
+```
+$ sonobuoy retrieve
+```
