How do you implement Kubernetes GitOps workflows and continuous deployment?

GitOps is a declarative approach to continuous deployment where Git repositories serve as the single source of truth for infrastructure and application configurations.\n\nGitOps Principles:\n• Declarative: Everything described declaratively\n• Versioned: All changes tracked in Git\n• Pulled automatically: Agents pull changes from Git\n• Continuously reconciled: Desired state maintained\n\nGitOps Tools:\n• ArgoCD: Declarative GitOps for Kubernetes\n• Flux: GitOps operator for Kubernetes\n• Jenkins X: Cloud-native CI/CD with GitOps\n• Tekton: Kubernetes-native CI/CD pipelines\n\nWorkflow Implementation:\n1. Developer commits code changes\n2. CI pipeline builds and tests\n3. CI updates deployment manifests in Git\n4. GitOps operator detects changes\n5. Operator applies changes to cluster\n6. Monitoring validates deployment\n\nExample ArgoCD Application:\napiVersion: argoproj.io/v1alpha1\nkind: Application\nmetadata:\n name: myapp\nspec:\n source:\n repoURL: https://github.com/company/k8s-manifests\n path: apps/myapp\n targetRevision: HEAD\n destination:\n server: https://kubernetes.default.svc\n\nBest Practices:\n• Separate app and config repositories\n• Use pull-based deployments\n• Implement proper RBAC\n• Monitor drift detection\n• Automate rollback procedures
