[^1]: GOTK is shorthand for the [GitOps Toolkit](https://toolkit.fluxcd.io/components/) APIs and Controllers
|
|
|
|
|
|
|
|
|
|
[^2]: Versioning: Flux 2 is a multi-service architecture, so requires a more complex explanation than Flux 1:
|
|
|
|
|
- Flux 2 CLI follows [Semantic Versioning](https://semver.org/) scheme
|
|
|
|
|
- The GitOps Toolkit APIs follow the [Kubernetes API versioning](https://kubernetes.io/docs/reference/using-api/#api-versioning) pattern. See [Roadmap](https://toolkit.fluxcd.io/roadmap/) for component versions.
|
|
|
|
|
- These are coordinated for cross-compatibility: For each Flux 2 CLI tag, CLI and GOTK versions are end-to-end tested together, so you may safely upgrade from one MINOR/PATCH version to another.
|
|
|
|
|
|
|
|
|
|
[^3]: The GOTK Custom Resource Definitions which are at `v1beta1` and `v2beta1` and their controllers are considered stable and production ready. Going forward, breaking changes to the beta CRDs will be accompanied by a conversion mechanism.
