@ -11,14 +11,17 @@ The role performs four main tasks:
3. **Verify the cluster state** after initialization, displaying the `sealos` version and the current Kubernetes nodes.
4. **Verify GPU access** by deploying the official NVIDIA device plugin and running a small CUDA workload.
When `sealos_version` is set to `latest` (the default), the role automatically
fetches the most recent stable release from GitHub.
The following command is used to create the cluster (example with one master and one worker):
```bash
sealos run \
registry.cn-shanghai.aliyuncs.com/labring/kubernetes:v1.29.9 \
registry.cn-shanghai.aliyuncs.com/labring/cilium:v1.13.4 \
registry.cn-shanghai.aliyuncs.com/labring/helm:v3.9.4 \
registry.cn-shanghai.aliyuncs.com/labring/kubernetes:<latest> \
registry.cn-shanghai.aliyuncs.com/labring/cilium:<cilium_version> \
registry.cn-shanghai.aliyuncs.com/labring/helm:<helm_version> \
--masters 172.16.11.120 \
--nodes 172.16.11.152 \
--env '{}' \
