:::caution[翻译进行中]

本实验的完整中文翻译尚未完成。为避免命令、固定提交版本、安全警告和实测输出在翻译期间产生偏差,请暂时使用[英文版实验](/tutorials/labs/dynamic-mig-rtx-pro)。

英文版包含完整的端到端操作:构建 HAMi 提交 `634bf2b32e68`、备份与受控交接、MIG Manager 所有权警告、`operatingmode` 与 `migStrategy` 的区别、单个 `1g.24gb` 请求、四个位置饱和、`1g.24gb` 与 `2g.48gb` 混合部署、相邻 CUDA 工作负载持续运行时的选择性回收、设备插件重启后的 UUID 稳定性、第五个 Pod 溢出到第二张 GPU,以及清理和运维陷阱。

## 验证环境

| 组件 | 实测值 |
| ----------- | ------------------------------------------------ |
| GPU | 8 × NVIDIA RTX PRO 6000 Blackwell Server Edition |
| NVIDIA 驱动 | `610.43.02` |
| Kubernetes | `v1.35.6` |
| 操作系统 | Ubuntu 24.04.4 LTS |

:::danger[只能有一个 MIG 硬件状态管理者]

NVIDIA GPU Operator MIG Manager 与 HAMi Dynamic MIG 都会创建和销毁 GI/CI。两者不得同时管理同一张物理 GPU。迁移现有节点前,请遵循固定版本的 [Dynamic MIG 迁移指南](https://github.com/Project-HAMi/HAMi/blob/634bf2b32e68e07d3fbcbd6da1ee079392fc07c1/docs/develop/dynamic-mig-migration.md)。

🌐 Web query:

nvcr.io/nvidia/k8s/cuda-sample:vectoradd-cuda12.5.0-ubuntu22.04 Dockerfile non-root UID 65532

💡 Result:

The image nvcr.io/nvidia/k8s/cuda-sample:vectoradd-cuda12.5.0-ubuntu22.04 does not inherently enforce a non-root user [1][2]. Like many standard NVIDIA CUDA base images, it typically defaults to the root user [3]. The user ID 65532 mentioned in your query is a common non-root UID (often referred to as 'nonroot') used in specific NVIDIA hardened container images, such as those for the NVIDIA GPU Operator, to adhere to security best practices and the principle of least privilege [4][5]. If you need to run a container as a non-root user (e.g., UID 65532) while maintaining GPU access, keep the following technical considerations in mind: 1. Permission to Devices: Access to NVIDIA GPU devices is managed by the NVIDIA Container Toolkit [6]. The toolkit automatically injects the necessary group IDs (GIDs) from the host into the container, allowing non-root users to access device nodes (such as /dev/nvidia0) without needing root privileges [6]. 2. Group Warnings: You may see warnings about unresolved GIDs in the container's /etc/group file [6]. This is a cosmetic issue because the device access is granted via the group ID itself, not by resolving the group name [6]. 3. Custom Implementation: To run the referenced cuda-sample image as non-root, you would typically need to extend it via a Dockerfile or configure the Kubernetes Pod security context to run as the desired user [3]. Ensure that any directories required by your application (like cache or output paths) are owned by your chosen UID [3][5]. For environments requiring high security, refer to NVIDIA's hardened container guidelines, which emphasize using specific runtime images already configured for non-root execution [5].

Security Misconfiguration (CWE-250)

Reachability: Internal · Exploitability: Difficult

Apply a hardened security context to both workload paths.

Both workloads run the CUDA container without restrictions on its user or privilege-escalation policy. Add runAsNonRoot, allowPrivilegeEscalation: false, dropped capabilities, and seccompProfile: RuntimeDefault to both cuda containers. Use UID 65532 only after confirming that the image can execute /cuda-samples/vectorAdd and write its files under /tmp as that UID.
