📝 WalkthroughWalkthroughThe GPU partitioning lab now uses AWS and GCP tabs for manifest workflows. AWS instructions copy manifests to EC2. The lab also expands OOM verification, adds compute-Pod checks, and documents optional HAMi WebUI port forwarding. ChangesGPU partitioning lab documentation
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟠 High · up to The AWS lab instructions currently contain commands that will fail unless placeholders are replaced and expose the WebUI on all network interfaces, which could make it reachable from the public internet; the PR should be corrected before merge.

In `@tutorials/labs/gpu-partitioning.md`:
- Around line 102-109: Update all three AWS copy commands in the tutorial to use
the `NODE_PUBLIC_IP` variable instead of the hardcoded `15.236.203.204` host,
and consistently use the exact PEM path established in Step 1.3
(`~/Downloads/hami-eks.pem`).
- Around line 100-111: Correct the repeated terminal instructions in all
affected sections: change “seperate” to “separate” and replace “Go back to your
on EC2 terminal” with “Return to the EC2 terminal.”
- Around line 136-137: Add a blank line between each provider-tab fenced code
block’s closing fence and the following </TabItem> in the tutorial, including
the block near the reported location, so the repeated pattern satisfies
Markdownlint MD031.
- Around line 277-282: Update the expected OOM output in the tutorial to use
ellipses or placeholders for the variable process ID, thread ID, allocator
details, memory values, and repeated HAMi-core error count. Preserve stable
assertions such as “Hit the limit after ...” and “CUDA out of memory.”
- Around line 427-434: Update the WebUI access instructions to remove the
default kubectl port-forward binding to 0.0.0.0 and use localhost binding
through an SSH -L tunnel instead. Keep the WebUI reachable via the remote
machine without exposing port 3000 on all VM interfaces; if public access
remains documented, restrict it to the student’s IP and include authentication
and HTTP-exposure requirements.

Do not expose the WebUI on all VM interfaces by default.
--address 0.0.0.0 binds the port forward to every EC2 interface. The public-IP URL then requires an inbound security-group rule and exposes port 3000 to every source allowed by that rule. Prefer an SSH tunnel with localhost binding. If public access is required, restrict the rule to the student's IP and document the authentication and HTTP exposure.
Safer default
-kubectl port-forward --address 0.0.0.0 service/my-hami-webui 3000:3000 --namespace=kube-system
+kubectl port-forward service/my-hami-webui 3000:3000 --namespace=kube-systemAccess the remote port through an SSH -L tunnel.

Updates the GPU partitioning lab instructions to ensure the example YAML manifests are available on the AWS EC2 instance before they are applied with
kubectl.Changes
scp.kubectl applycommands to use the manifests from their location on the EC2 instance.Why did we need it
The previous instructions assumed that the HAMi repository and YAML manifests were available on the same machine where
kubectlwas being executed. This is not the case in the AWS EC2 setup, where the repository is typically on the user's local machine whilekubectlis run on the remote EC2 instance.This update ensures the GPU partitioning lab can be followed successfully on AWS without changing the existing GCP instructions.
