How do you manage shared/common configuration across many Applications?

Advanced

Answer

Factor shared config into a common Helm chart or Kustomize base that apps reference, use ApplicationSet templates for consistency, and centralize cross-cutting policy in Projects. This avoids duplication so a change to shared defaults propagates to all consuming apps.
Real-world example All services inherit standard labels, resource limits, and network policies from a shared Kustomize base.
