Gophercloud is a comprehensive Go SDK for OpenStack cloud APIs. It provides typed client libraries for over 20 OpenStack services, including compute, networking, block storage, identity, load balancing, container orchestration, bare metal, DNS, key management, and more. The library handles authentication via Keystone (v2/v3), clouds.yaml, environment variables, or direct options, and includes a robust pagination framework (linked, marker, single page) used by all list operations. It follows consistent patterns: each resource has Create/Get/List/Update/Delete functions, builder interfaces for request options, and result types with Extract() methods. The codebase is heavily tested with both unit tests (HTTP mock fixtures) and acceptance tests (against real OpenStack deployments). While primarily a library for infrastructure management, it also exposes utilities like pointer helpers, JSON time parsing, and config file loading. The architecture is modular and extensible, with many reusable patterns.
