Pros
  • Reconciles Kubernetes resources from Git repositories and configuration sources
  • Supports Helm, Kustomize, image automation, dependencies, and multi-tenancy
  • Connects with Git providers, CI systems, registries, and notification tools
  • Continuously reconciles declared configuration with live cluster state
  • Synchronizes configuration across GKE and supported attached clusters
  • Supports Git, OCI images, Helm, Kustomize, and staged rollouts
Cons
  • Requires customer-managed Kubernetes clusters
