+# GPU Kubernetes Role
+
+This document describes how to use the `gpu-k8s` role to deploy a simple Kubernetes cluster with NVIDIA GPU support.
+
+## Overview
+
+The role performs three main tasks:
+
+1. **Create the Kubernetes cluster** using [sealos](https://github.com/labring/sealos). It runs the provided `sealos run` command to bootstrap the master and worker nodes.
+2. **Install NVIDIA drivers and container runtime** on the target hosts so that Kubernetes can access GPU resources.
+3. **Verify GPU access** by deploying the official NVIDIA device plugin and running a small CUDA workload.
+
+The following command is used to create the cluster:
+
+```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 \
+  --masters 172.16.11.120 \
+  --nodes 172.16.11.152 \
+  --env '{}' \
+  --cmd "kubeadm init --skip-phases=addon/kube-proxy"
+```
+
+After the cluster is running the role installs the NVIDIA device plugin and runs a test pod to ensure `nvidia-smi` works inside the cluster.
+
+## Usage
+
+Add the role to your playbook:
+
+```yaml
+- hosts: all
+  roles:
+    - gpu-k8s
+```
+
+Run the playbook with your inventory that contains the master and node IP addresses.
+
+```bash
+ansible-playbook -i inventory/hosts/all playbooks/demo_gpu_k8s.yml
+```
+
+The final step prints the output of `nvidia-smi` from inside a Kubernetes pod, confirming that the GPU is available.
