GitOps with Argo CD on AKS: Patterns for Enterprise Application Delivery

GitOps replaces imperative cluster changes with declarative manifests in Git. On Azure Kubernetes Service, Argo CD has become the de facto delivery layer: ApplicationSets discover repos by convention, sync policies enforce desired state, and rollbacks are a git revert away.

Enterprise patterns that work well include one repo per application with Kustomize overlays per environment, image tags bumped by CI after Trivy scans pass, and separate namespaces per tenant or product line. Platform teams own cluster add-ons (ingress, cert-manager, observability) in a dedicated infra repo applied via Pulumi—keeping application Deployments out of imperative scripts.

cloudstrata operates multi-environment AKS fleets for clients and our own products using this model. We help teams design ApplicationSet generators, secret bootstrap flows, and promotion workflows so developers push to main and Argo CD handles the rest—safely and audibly.
