GitHub developed a Go library named Vulcanizer to manage Elasticsearch clusters more efficiently by providing a high-level API focused on administrative tasks, rather than indexing and querying data, which existing libraries cater to. Initially, GitHub's internal tools relied on proprietary Bash and Ruby scripts, which were difficult to open source due to their bespoke nature and dependency on GitHub's infrastructure. By transitioning to Go, inspired by other successful internal projects, GitHub aimed to create composable and reusable software that could be open-sourced. Despite challenges with proprietary protocols and dependencies, GitHub decoupled Vulcanizer from its internal libraries, enabling its use with diverse ChatOps infrastructure and service discovery tools. Vulcanizer offers a simple command-line interface for tasks like querying cluster health, managing node allocations, and updating cluster settings, encouraging community contributions and ensuring best practices in engineering and release management.
