#git-workflow

Implement GitOps methodology using ArgoCD for declarative, Git-driven continuous delivery and application lifecycle management. GitOps principles: 1. Git as single source of truth: all configuration in version control, declarative infrastructure. 2. Automated deployment: git commits trigger deployment pipeline, no manual kubectl commands. 3. Observability: clear audit trail, drift detection, status reporting. 4. Security: Git-based access control, signed commits, policy enforcement. ArgoCD configuration: 1. Application setup: source repository, target cluster, sync policy configuration. 2. Sync strategies: automatic (immediate), manual approval, sync waves for ordered deployment. 3. Health checks: resource status monitoring, custom health checks for CRDs. 4. Rollback capability: Git revert triggers automatic rollback, previous state restoration. Repository structure: 1. Application manifests: Kubernetes YAML, Helm charts, Kustomize overlays. 2. Environment separation: dev/staging/prod directories, overlay configurations. 3. Secret management: external-secrets operator, sealed-secrets, Vault integration. Multi-cluster management: 1. Cluster registration: multiple Kubernetes clusters, environment-specific deployments. 2. Application sets: template-based application deployment, cluster-specific configurations. Monitoring integration: 1. Slack notifications: deployment status, failure alerts, approval requests. 2. Metrics: deployment frequency, lead time, success rate tracking (target: >95% success rate).
