Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces support for IBM Spectrum Symphony within the Google Cloud Cluster Toolkit. It provides modular blueprints and automation scripts to deploy and manage Symphony clusters on both Google Compute Engine (GCE) and Google Kubernetes Engine (GKE). The changes facilitate automated infrastructure setup, custom image creation, and elastic compute scaling, significantly streamlining the deployment process for high-performance computing workloads on Google Cloud.

Highlights

• IBM Spectrum Symphony Support: Added comprehensive support for deploying IBM Spectrum Symphony clusters using Google Cloud Cluster Toolkit, including blueprints for both GCE and GKE environments.
• Infrastructure Automation: Introduced automated infrastructure provisioning, custom base image creation via Packer, and dynamic cloud bursting configurations for both GCE MIGs and GKE.
• Documentation and Examples: Added detailed READMEs and configuration examples for deploying Symphony on GCE and GKE, covering prerequisites, deployment steps, and cluster management.
• Operational Enhancements: Integrated Google Cloud Ops Agent for logging and monitoring, and added support for containerized compute workloads on GKE via a custom Kubernetes operator.

Code Review

This pull request introduces blueprints, scripts, and configuration files to deploy IBM Spectrum Symphony on Google Compute Engine (GCE) and Google Kubernetes Engine (GKE) using the Google Cloud Cluster Toolkit. The reviewer provided valuable feedback on several issues: ensuring /etc/sudoers.d/ files have 0440 permissions to prevent sudo from ignoring them, relaxing fixpack directory permissions from 770 to 755 so the egoadmin user can execute installation scripts, wrapping integer conversions in try-except blocks to prevent script crashes, adding set -e to build scripts for fail-fast behavior, and using wildcards for Python virtual environment paths to avoid version-specific failures.
