and secondary GPU index variables, then generate both filterdevices.index
exclusion lists from those variables. Update the mixed-profile configuration and
the Step 8 sed command to use the same variables rather than fixed index 4 or a
literal exclusion-list replacement, ensuring the fifth Pod can spill to the
selected secondary GPU.
- Around line 518-532: Scope the device-plugin pod selection, deletion, rollout
wait/restart, and log retrieval in this migration step to $NODE instead of
selecting any GPU node via .items[0]. Ensure the commands target only the
device-plugin Pod scheduled on $NODE, or explicitly validate that the cluster
has a single matching node before proceeding.

🌐 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.

Closing this for now |

@mesutoezdil could you reopen this one? It is a verified hardware lab rather than a new guide page, and all review feedback here was addressed before the close: CI is green on a4e2352 and both CodeRabbit threads are resolved. #654 also merged as Lab 15 this morning, so labs are still landing while #689 is in progress. I will renumber this to the next free number and move it into whatever tutorials layout #838 settles on once that lands. |
sure! |

Thanks! Renumbered to Lab 17 in 614b620 and merged master in, keeping the Lab 15 SGLang sidebar entry ahead of this one. I left Lab 16 for #655 since it was queued first. The examples directory, titles, sidebar labels, and paths are updated in both locales, and the overview now lists the lab as a bullet instead of text appended to the card grid line. |

Adds Lab 15, which builds a pinned HAMi snapshot and walks the full Dynamic MIG lifecycle on RTX PRO 6000 hardware: per-Pod MIG placement, mixed profiles, selective reclamation, restart recovery, and multi-GPU spillover. English and Chinese, with the example manifests. Signed-off-by: Saiyam Pathak <saiyam911@gmail.com>
- Align the zh tag with the en slug (gpu-partitioning) so tag pages match across locales. - Parameterize the GPU choice: Step 1 defines PRIMARY_GPU and SECONDARY_GPU, Step 3 checks the one-GPU exclusion list, Step 6 derives the UUID from PRIMARY_GPU, and Step 8 removes SECONDARY_GPU from the list with a variable-driven sed and prints the result. - Scope the device-plugin Pod selection in Step 7 to $NODE and add a Step 1 check that $NODE is the only gpu=on node before the DaemonSet restarts.

Replace the literal filterdevices.index list in the supplied values with a placeholder. Step 3 renders the one-GPU list from the node's nvidia-smi inventory minus PRIMARY_GPU, and Step 8 renders the two-GPU list from the same inventory minus PRIMARY_GPU and SECONDARY_GPU, so no manual edit of the exclusion list is needed. Default values reproduce the verified run. Signed-off-by: Saiyam Pathak <saiyam911@gmail.com>

@mesutoezdil trailers are stripped from all five commits and the branch is rebased onto current master, no content change. It is back at Lab 17 as you specified — I briefly pushed Lab 16 by mistake and reverted it, so ignore that if you happened to pull in between. CI is green. On the overview layout: happy to take a pass at it. Anything specific you would like changed, or should I propose something and screenshot it here first? |
Stack the eight steps into three labeled phases (prepare, allocate, recover and spill) instead of one long row, so the step boxes are readable at normal page width. Signed-off-by: Saiyam Pathak <saiyam911@gmail.com>

Took a pass at the overview in e2519a3: the eight steps are now stacked into three labeled phases (prepare the node, allocate MIG per Pod, prove recovery and spillover) instead of one long row, so each box has room. Preview: https://deploy-preview-793--project-hami.netlify.app/tutorials/labs/dynamic-mig-rtx-pro#lab-overview once Netlify finishes. Happy to adjust if you had a different shape in mind, and looking forward to your RTX PRO run. |

What type of PR is this?
/kind documentation
What this PR does / why we need it:
Adds Lab 17: the full Dynamic MIG lifecycle on RTX PRO 6000 hardware. The lab builds a pinned HAMi snapshot, then verifies per-Pod MIG placement, mixed profiles on one GPU, selective reclamation, recovery across a device-plugin restart, and multi-GPU spillover. English and Chinese, with the example manifests under
tutorials/labs/examples/17-dynamic-mig-rtx-pro/.Which issue(s) this PR fixes:
None.
Special notes for your reviewer:
Numbering: #654 landed as Lab 17 and #655 was queued first for Lab 17, so this lab is Lab 17. master is merged in, keeping the SGLang sidebar entry ahead of this one.
Every command and output in the lab was run on the described hardware (8x NVIDIA RTX PRO 6000 Blackwell Server Edition, driver 610.43.02, Kubernetes v1.35.6). The build is pinned to commit
634bf2b, which is included in v2.10.0; a note says so, and a later revision can switch the lab to the released artifacts once it is re-verified against them.AI assistance disclosure: written primarily with Claude Code, directed and reviewed by me.
