+# OpenEuler
+
+[OpenEuler](https://www.openeuler.org/en/) Linux currently only supports the containerd runtime.
+
+**Note:** that OpenEuler Linux is not currently covered in kubespray CI and
+support for it is currently considered experimental.
+
+At present, only `openEuler 22.03 LTS` has been adapted, which can support the deployment of aarch64 and x86_64 platforms.
+
+There are no special considerations for using OpenEuler Linux as the target OS
+for Kubespray deployments.
