Building GitOps Workflows

Overview

Construct GitOps workflows using ArgoCD or Flux to implement declarative, Git-driven continuous delivery for Kubernetes. Generate Application/Kustomization manifests, configure sync policies, set up multi-environment promotion, and implement RBAC and notification integrations.

Prerequisites

• Kubernetes cluster accessible via kubectl with admin permissions
• Git repository for storing Kubernetes manifests (separate from application code recommended)
• ArgoCD or Flux installed on the cluster, or Helm charts ready for installation
• Container images built and pushed to a registry accessible from the cluster
• SSH key or access token for Git repository authentication from the cluster

Instructions

1. Choose the GitOps tool based on requirements: ArgoCD for UI-driven management, Flux for lightweight Git-native approach
2. Design the repository structure: environments/{dev,staging,prod}/ with Kustomize overlays or Helm values per environment
3. Generate ArgoCD Application or Flux Kustomization manifests pointing to the Git repository path for each environment
4. Configure sync policy: enable automated.selfHeal and automated.prune for non-production; use manual sync for production
