+# kubectl-kruise
+kubectl plugin for OpenKruise
+
+`kubectl` supports a plug-in mechanism, but the rollout and other related operations provided by this tool itself only support the native workload resources of Kubernetes.
+Therefore, we need to create a kubectl plugin for OpenKruise, through which community users can use kubectl to operate Kruise’s workload resources.
+
+So, `kubectl-kruise` was created.
+
+### How to use
+The development of  `kubectl-kruise`  is in progress, if you wanna to experience it, you can clone it and make it:
+
+```
+make build && cp kubectl-kruise /usr/local/bin
+
+```
+
+### Use with command-line
+
+Then you can operate Openkruise resource by `kubectl-kruise`.
+By now the `rollout` cmd such as `rollout undo`, `rollout status`, `rollout history` have been developed.
