GitOps: FluxCD vs ArgoCD
GitOps makes Git the source of truth for cluster and infrastructure state, with a controller that continuously reconciles actual state to declared state. FluxCD and ArgoCD are the two dominant Kubernetes GitOps controllers. Flux is CLI-first, composable, and lightweight; ArgoCD is UI-first, feature-rich, and easier for teams new to GitOps. Both are excellent; the choice is mostly about team workflow and operational style.
Puncte-cheie
- FluxCD: CLI-driven, composable controllers (source, kustomize, helm), lightweight, integrates well with existing CI.
- ArgoCD: web UI with app topology, sync status, and manual sync controls; easier onboarding for teams new to GitOps.
- Both support Kustomize and Helm; Flux's Helm controller handles releases natively, ArgoCD wraps Helm as a template engine.
- Flux is push-less and pull-based: the cluster pulls from Git, no CI credentials needed in the cluster.
- ArgoCD's UI is a genuine operational advantage for debugging sync failures and visualizing app health.
- Multi-cluster: ArgoCD supports multi-cluster from one control plane; Flux requires a controller per cluster.
- Secrets: both integrate with SOPS and external secret operators; ArgoCD has built-in SOPS support, Flux uses external controllers.
- Start with one app, one environment, and one controller. Expand only after the reconciliation loop is trusted.
Întrebări frecvente
Flux or ArgoCD?
Flux for CLI-first, composable, multi-tenant platforms. ArgoCD for teams wanting a UI and faster onboarding. Both are production-proven.
Can I switch between them?
Yes, but it is a migration project: manifests are portable, controller-specific config and secrets handling differ.
Do I still need CI?
Yes. GitOps handles deployment; CI handles build, test, and image push. They are complementary, not competing.
How do I handle secrets in GitOps?
Never commit plaintext. Use SOPS, Sealed Secrets, or external secret operators that pull from a vault at reconcile time.
