The Dagger Go SDK is a new way to develop CI/CD pipelines as code and run them anywhere, introduced on October 25, 2022. It's designed for Go developers who want their CI pipelines to be written in Go, allowing for instant local testing, portability, superior caching, compatibility with the Docker ecosystem, and cross-language instrumentation. The SDK may not be suitable for those who don't know Go or prefer YAML programming, container skeptics, or those seeking a different development approach. It's intended to replace artisanal scripts and unify continuous delivery across organizational silos.
