Upstream (disambiguation)
Glossary Page
The term "upstream" can have different meanings depending on the context. It can refer to the core Kubernetes codebase or the source repository from which another repository was forked. Within the Kubernetes community, "upstream" typically refers to the core Kubernetes codebase that serves as the foundation for other tools and code in the ecosystem. Community members may suggest moving a feature upstream, which means incorporating it into the core codebase instead of relying on a plugin or third-party tool. In GitHub or git, "upstream" conventionally refers to the source repository, while the forked repository is considered downstream.
