📝 WalkthroughWalkthroughThe online installation lab now supports AWS and GCP GPU VMs. It adds AWS provisioning, kernel setup, provider-specific Kubernetes installation and verification, GPU registration formatting, Prometheus checks, and WebUI access instructions. ChangesCloud installation lab
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to Several documented paths can currently fail or leave users unable to complete the lab: the GCP version combination is unsupported, AWS instances may not be reachable over SSH, the GCP WebUI forwarding does not expose the service locally, and the kernel-selection script can choose an invalid default. These issues should be fixed before merging. Suggested labels: Suggested reviewers: 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Inline comments:
In `@tutorials/labs/online-install.md`:
- Around line 712-721: Update the description following the GPU registration
verification command to identify the sample as a JSON array containing one
object per GPU, replacing the current wording that describes it as a JSON object
per GPU.
- Around line 451-459: Update the repeated 3.9 and 4.0 headings in the AWS and
GCP provider sections so each heading has a unique anchor, preferably by
including the provider name while preserving the existing step numbering and
content.
- Around line 786-788: Update the SSH command’s -i argument to use the same
key-file placeholder convention as the other SSH command: either define and
reuse a complete KEY_FILE value or remove the appended /hami-eks.pem suffix when
the placeholder already represents the file path.
- Line 75: Align the GCP installation path with GPU Operator v25.3.0 by changing
the Kubernetes prerequisite, repository references, and expected v1.34.8 output
to Kubernetes 1.33. Update all related version-specific references in the
tutorial consistently, unless instead pinning a GPU Operator release that
supports Kubernetes 1.34 and retesting the complete path.
- Around line 125-135: Update the “Create the EC2 Spot Instance” instructions
and its aws ec2 run-instances command to define or import KEY_NAME, SUBNET_ID,
and SECURITY_GROUP_ID, include the subnet and security-group options, and enable
public IPv4 association. Ensure the referenced security group permits TCP port
22 only from the user’s workstation IP.
- Around line 796-800: Add the GCP SSH tunnel command after the kubectl
port-forward command, instructing users to run it from a second local terminal
while port-forwarding remains active, and clarify that they should then visit
http://localhost:3000 locally.
- Around line 158-166: Validate GRUB_ID after the grep/sed lookup and exit
before modifying /etc/default/grub when it is empty; also verify that a
^GRUB_DEFAULT= entry exists before running the sed update. Keep the existing
kernel-selection and update-grub flow unchanged when both checks pass.

AWS EC2 RunInstances omitted subnet public IPv4 auto-assign default security group SSH --associate-public-ip-address --security-group-ids documentation
💡 Result:
When using the AWS EC2 run-instances command or API, omitting specific parameters triggers the following default behaviors: Subnet: If you do not specify a --subnet-id, Amazon EC2 automatically selects a default subnet from your default VPC [1][2][3]. If you do not have a default VPC, you must specify a subnet ID in your request [1][2][3]. Security Group: If you do not specify --security-group-ids or --security-groups, Amazon EC2 assigns the instance to the default security group associated with the VPC [1][2][3]. Public IPv4 Address: The behavior of --associate-public-ip-address depends on the destination subnet. If you launch an instance into a default subnet, a public IPv4 address is assigned by default [4]. If you launch into a non-default subnet, a public IPv4 address is not assigned unless you explicitly include the --associate-public-ip-address flag [5][4]. Important Note: If you specify a network interface in your request, you must specify the subnet and security groups as part of that network interface configuration, rather than using the top-level parameters [2][6]. Additionally, the --associate-public-ip-address option can only be used when launching a single instance and cannot be specified if you have also defined a custom network interface [2][4].

Make the EC2 instance reachable over SSH.
The launch command does not specify a subnet, security group, or public IPv4 association. A non-default subnet does not assign a public IPv4 address by default, and the default security group does not allow SSH from the user's workstation. Define SUBNET_ID and SECURITY_GROUP_ID, add the corresponding launch options and --associate-public-ip-address, restrict TCP 22 to the user's IP address, and create or import the KEY_NAME key pair before running the command.

This lab expands the HAMi tutorial documentation to support AWS GPU infrastructure alongside the existing Google Cloud GPU virtual machine.
What Changed:
The introductory description has been updated to state that the lab supports either an AWS or a Google Cloud GPU virtual machine.
Added instructions for creating an AWS EC2 GPU instance using the AWS CLI.
Documented the requirement for AWS GPU/Spot vCPU quota before creating the instance.
Added Kubernetes and GPU Operator compatibility guidance that directs users to NVIDIA's platform-support documentation to verify that the selected Ubuntu and Kubernetes versions are supported together, because the NVIDIA driver, Linux kernel, Kubernetes version, and GPU Operator need to work together.
The kernel was downgraded to v6.8 because the AWS default kernel is not compatible with the NVIDIA GPU Operator v25.3.0 setup used in this lab.
Added tabs for
AWSandGCPto separate cloud-provider-specific instructionsUpdated the HAMi WebUI port-forwarding instructions to use the VM's public IP address instead of localhost.
Added my name
creativeklvnto the authors list to credit my contribution to the lab documentation updates.Previously, the lab instructions were primarily focused on the Google Cloud environment. Adding AWS allows users to complete the same HAMi workflow without needing a GCP environment.
The lab should provide the same overall HAMi experience regardless of whether the user chooses:
AWS EC2 GPU or Google Cloud GPU VM
Fixes #736
