GitOps at Scale: Kubernetes & ArgoCD for Microservices
Answer-first: Eliminate manual deployment errors and drift by implementing split-repo GitOps with ArgoCD. By configuring the selfHeal: true policy, ArgoCD automatically corrects cluster mutations. Structure configurations using Kustomize overlays and the App-of-Apps pattern, enabling safe, auditable rollbacks via simple git revert commands. What You’ll Learn That AI Won’t Tell You The security risks of running kubectl apply in production and how the App-of-Apps pattern eliminates credential exposure. Practical steps to configure annotation-based sync filtering in ArgoCD to isolate multi-tenant microservices deployments. Building 21 well-architected Go microservices is only half the battle. If your deployment process relies on an engineer running kubectl apply from their laptop on a Friday afternoon, you haven’t built an enterprise platform — you’ve built a ticking time bomb. ...
