Jack developed single-node deployment support for OpenSearch within the Panfactum/stack repository, enhancing the kube_opensearch Terraform module to allow flexible cluster sizing. By adjusting cluster settings based on the replica_count variable and removing the enforced minimum of three replicas, Jack enabled cost-effective and rapid deployment options for development and testing environments. This work leveraged Terraform and HCL, integrating with AWS and Kubernetes infrastructure as code practices. The focused implementation maintained clear change traceability, supporting future enhancements and code reviews. Jack’s contribution addressed the need for more adaptable OpenSearch topologies, improving resource efficiency and accelerating onboarding for experimental use cases.
