A Chef cookbook for building and bootstrapping AWS ParallelCluster, an HPC cluster management tool for AWS.
The AWS ParallelCluster Cookbook is a Chef cookbook that provides infrastructure-as-code recipes to automate the provisioning and configuration of AWS ParallelCluster, a cluster management tool for high-performance computing (HPC) workloads on AWS. It defines modular recipes for building and bootstrapping cluster nodes, schedulers (like Slurm and AWS Batch), and shared filesystems, enabling repeatable and test-driven deployments.
DevOps engineers, HPC administrators, and infrastructure developers who manage or automate the deployment of HPC clusters on AWS using AWS ParallelCluster. It is also for contributors to the AWS ParallelCluster project who need to modify or test the underlying infrastructure code.
Developers choose this cookbook because it offers a modular, test-driven approach with comprehensive automated testing (ChefSpec and Kitchen) for reliable cluster deployments. Its integration with AWS ParallelCluster provides a standardized, automated way to manage HPC infrastructure, reducing manual configuration errors and ensuring consistency across environments.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Organized into functional cookbooks like entrypoints, platform, and environment, allowing clear separation of concerns and easier maintenance, as detailed in the code structure section.
Includes ChefSpec unit tests and Kitchen integration tests for Docker and EC2, with CI/CD via GitHub Actions, ensuring recipe reliability across environments, as highlighted in the development section.
Supports custom scripts to create/destroy AWS resources like network interfaces during test phases, enabling complex deployments without manual intervention, as described in the lifecycle hooks section.
Tests run on various OS platforms and architectures with documented workarounds for known Docker and EC2 issues, enhancing cross-environment support, as noted in the known issues sections.
Requires installing cinc-workstation, setting locale variables, and managing known issues with Docker (e.g., architecture conflicts) and EC2 (e.g., key type requirements for Ubuntu22), which adds significant initial overhead.
Tightly integrated with AWS services and the Chef toolchain, limiting portability to other cloud providers or infrastructure-as-code frameworks, making it less flexible for heterogeneous environments.
The README assumes prior knowledge of Chef, Kitchen, and AWS ParallelCluster, with dense technical details that can be overwhelming for developers new to HPC or infrastructure automation.
