❓ FREQUENTLY ASKED QUESTIONS
Q: What is GitOps and why should I use it?
A: GitOps uses Git as the single source of truth for infrastructure — every change
is versioned, auditable, and automatically synced to your cluster by ArgoCD.
Q: ArgoCD vs Flux CD — which is better?
A: ArgoCD has a UI dashboard and is easier for beginners; Flux is more lightweight
and GitOps-native. Both are CNCF projects. This video uses ArgoCD.
Q: Do I need to know Kubernetes before learning GitOps?
A: Basic Kubernetes knowledge (pods, deployments, services) is recommended.
Links to a beginner K8s video are in the description above.
Q: Is ArgoCD free?
A: Yes — ArgoCD is 100% open source and free to use on any Kubernetes cluster.
