Inline comments:
In `@docs/get-started/local-testing-with-mock-gpu.md`:
- Line 6: Remove the “or Minikube” wording from the guide’s introductory
references, including the text around the mockDevicePlugin setup, so the
documented workflow consistently targets Kind only.
- Around line 190-192: Update the kubectl events query to retain the
FailedScheduling reason filter while adding
involvedObject.name=mock-gpu-oversubscribed, restricting results to the intended
mock-gpu-oversubscribed Pod.
- Line 31: Update the cluster setup documentation around the kind create cluster
command to pin the Kind node image and node configuration, or replace variable
cluster output values such as AGE, VERSION, cpu, ephemeral-storage, memory, and
pods with placeholders; ensure the documented output remains valid for the
chosen setup.
- Around line 136-149: Update the annotation verification example near “Inspect
the pod annotations” to query the HAMi annotations directly with a deterministic
JSONPath command instead of grep -A 10; retain the expected bind-gpu-idx,
bind-gpumem, and bind-gpucores values and avoid relying on annotation order or
unrelated annotations.
- Around line 59-66: Add a pre-verification step after the mock HAMi
installation that patches the mock node with a positive nvidia.com/gpu capacity
and the hami.io/node-nvidia-register annotation, then wait approximately 30
seconds for the mock device plugin to resync before Step 3.
- Around line 62-65: Update the Helm install example to pin chart version 2.9.0,
then revise the expected output to use version-independent checks: reference the
mock DaemonSet as hami-mock-device-plugin, avoid hardcoding its generated Pod
name, and expect hami-scheduler readiness as 2/2.
In `@docs/troubleshooting/troubleshooting.md`:
- Around line 185-190: Update the FailedScheduling event query in the
troubleshooting steps to target the Pending pod’s namespace with the kubectl
namespace option, while retaining the scheduler log command. Mention using all
namespaces only when the pod’s namespace is unknown.
- Around line 179-183: Replace the grep-based command in the
allocatable-resource verification step with a kubectl JSONPath query that
directly prints both status.allocatable nvidia.com/gpumem and
nvidia.com/gpucores values, each on its own line.

Project-HAMi HAMi mock device plugin node-nvidia-register annotation nvidia.com/gpu source
💡 Result:
In the HAMi project, the hami.io/node-nvidia-register annotation is a critical component of the communication protocol between the HAMi device plugin and the HAMi scheduler [1][2]. Because the standard Kubernetes device plugin API only supports reporting integer counts of devices—making it unable to convey detailed device attributes like VRAM size, compute capacity, model, or NUMA topology—HAMi uses node annotations to pass this hardware metadata to the scheduler [3]. The hami.io/node-nvidia-register annotation contains a formatted string representing the specifications of all NVIDIA GPU devices on a specific node [1][2]. The device plugin updates this annotation every 30 seconds [1][2]. The format for each device in the registration string is: {Device UUID},{device split count},{device memory limit},{device core limit},{device type},{device numa},{healthy} Multiple devices are separated by a colon (:), as seen in this example: GPU-00552014-5c87-89ac-b1a6-7b53aa24b0ec,10,32768,100,NVIDIA-Tesla V100-PCIE-32GB,0,true:GPU-0fc3eda5-e98b-a25b-5b0d-cf5c855d1448,10,32768,100,NVIDIA-Tesla V100-PCIE-32GB,0,true: The mock device plugin (project-hami/mock-device-plugin) is a specific implementation used to test this registration process [4][5]. It simulates virtual devices to enable the registration of resources that standard Kubernetes schedulers typically ignore, such as gpu-memory (nvidia.com/gpumem) and gpu-cores (nvidia.com/gpucores) [4][5]. By deploying this mock plugin, nodes can advertise these virtual resources in their status (allocatable and capacity), allowing developers to verify HAMi's scheduling logic without requiring physical hardware [4][5][6]. When used correctly, the mock plugin populates the required node annotations so the scheduler can recognize and manage these "mocked" GPU resources [4][6].

Initialize the mock node before verifying resources.
The mock device plugin requires a hami.io/node-nvidia-register annotation and a positive nvidia.com/gpu capacity. It does not create these inputs in a mock-only cluster. Without them, it does not register nvidia.com/gpumem or nvidia.com/gpucores.
Add the node patch and annotation before Step 3, then wait approximately 30 seconds for the plugin to resync.

Kubernetes kubectl get events default namespace --all-namespaces official documentation
💡 Result:
To view events in Kubernetes, the recommended and modern subcommand is kubectl events [1][2]. For events in the default namespace (or the namespace currently set in your context), you can simply run [2][3]: kubectl events To view events across all namespaces, use the --all-namespaces flag (or its short form -A) [1][4]: kubectl events --all-namespaces # OR kubectl events -A While the legacy command kubectl get events is still supported in many environments, kubectl events was introduced to provide a cleaner, more ergonomic interface specifically for listing event objects, including features like live-watching and simplified output [2]. When using the legacy kubectl get events command, the behavior regarding namespaces is consistent with other kubectl get commands: running it without arguments defaults to the namespace set in your current context, and appending --all-namespaces (or -A) will retrieve events from across the entire cluster [5].

Query events in the Pending pod's namespace.
The command uses the current namespace and can miss events for a Pending pod in another namespace. Use -n <namespace> for the target pod. Use --all-namespaces only when the pod namespace is unknown.

FailedScheduling event query in the troubleshooting steps to target the Pending
pod’s namespace with the kubectl namespace option, while retaining the scheduler
log command. Mention using all namespaces only when the pod’s namespace is
unknown.

Pull request overview
Adds a new “zero-hardware” hands-on lab to help users evaluate HAMi scheduling behavior on CPU-only local Kubernetes clusters (Kind/Minikube) using the built-in mockDevicePlugin, plus navigation and troubleshooting cross-links to make it discoverable.
Changes:
- Added a new Get Started tutorial for running HAMi locally with
mockDevicePlugin(including scheduling verification andFailedSchedulingdiagnostics). - Linked the new tutorial from the Troubleshooting guide as a recommended diagnostic path for
Pendingpods without real GPUs. - Registered the new tutorial in the Get Started sidebar.

- Same as above: this heredoc is a shell command, so the code fence should be
bashrather thanyamlfor accurate highlighting and copy/paste.
To observe how HAMi handles resource exhaustion without physical hardware, submit a second pod requesting more GPU memory than remains available on the node (e.g. requesting `7000` MiB when only `6144` MiB remain allocatable):
```yaml
cat <<EOF | kubectl apply -f -

Hi @rootsongjc @windsonsea @fishman , I've completed the local CPU-only mock GPU testing tutorial and verified the setup, scheduler behavior, and Docusaurus build. Could you please review the PR when you get a chance? Thank you! |
