Flux CD v2: multi-tenancy, Helm releases, image automation a notifikace.
Flux v2 Architektura¶
Flux v2 je postavený na GitOps Toolkit — sadě specializovaných kontrolérů:
- Source Controller — spravuje Git repos, Helm repos, OCI artefakty
- Kustomize Controller — aplikuje Kustomize overlays
- Helm Controller — řídí HelmRelease lifecycle
- Notification Controller — alerting a eventy
- Image Automation — automatický update image tagů v Gitu
