📝 WalkthroughWalkthroughThe PR adds bilingual Volcano HAMi-core Ascend vNPU soft-slicing documentation, a complete Lab 13 tutorial with Kubernetes examples, tutorial navigation and tags, and unlists three older blog posts. It also removes two event landing pages. ChangesAscend vNPU documentation
The Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🔵 Low · up to The PR adds runnable Ascend/Volcano tutorial examples with a small reported-memory inconsistency and Pods that lack baseline privilege restrictions. These bounded risks warrant owner follow-up, but the PR remains mergeable with explicit awareness. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

- Line 18: Update the vDeviceCount setting in the Ascend 310P3 device-node
configuration from 8 to 7, matching the driver’s maximum supported vNPUs per
card.
In `@tutorials/labs/examples/13-volcano-ascend-vnpu/03-ascend-vnpu-check.yaml`:

security context to the npu containers in

12-19: disable privilege escalation and configure a non-root UID that retains
the required Ascend device permissions.
In `@tutorials/labs/volcano-ascend-vnpu.md`:
- Around line 731-741: In tutorials/labs/volcano-ascend-vnpu.md lines 731-741,
revise the “Isolation is enforced per container” claim and evidence to state
only quota visibility/configuration, unless adding a workload allocation test
that demonstrates enforcement. Apply the identical evidence or wording change in
i18n/zh/docusaurus-plugin-content-docs-tutorials/current/labs/volcano-ascend-vnpu.md
lines 731-741; keep both translations consistent.
- Around line 361-365: Use a stable WEBSITE_ROOT (or return to the website
checkout) for manifest paths in tutorials/labs/volcano-ascend-vnpu.md at lines
361-365, 444, 521, and 612, and apply the same fix at the corresponding lines in
i18n/zh/docusaurus-plugin-content-docs-tutorials/current/labs/volcano-ascend-vnpu.md.
Ensure all scheduler and lab manifest commands resolve from the website checkout
regardless of the current directory.
- Around line 101-102: Update the label-inspection commands using kubectl at
tutorials/labs/volcano-ascend-vnpu.md lines 101-102 and
i18n/zh/docusaurus-plugin-content-docs-tutorials/current/labs/volcano-ascend-vnpu.md
lines 101-102 to use JSON-producing output, such as -o json or -o
jsonpath-as-json, so python3 -m json.tool can parse the result; apply the same
correction to the commands at lines 558-559 in both files.
- Around line 219-220: Update the kubectl download URL in both
tutorials/labs/volcano-ascend-vnpu.md (lines 219-220) and
i18n/zh/docusaurus-plugin-content-docs-tutorials/current/labs/volcano-ascend-vnpu.md
(lines 219-220) from v1.31.0 to v1.28.15, leaving the surrounding installation
commands unchanged.

replace the repeated 43,054 MiB value with the evidence-backed total of 43,050
MiB, or explain the 4 MiB discrepancy wherever 43,054 MiB is intentionally
retained. Update the paragraph and all later result rows consistently.
