# PRD: Argo CD Integration for Packaged Recommendations **Issue**: [#255](https://github.com/vfarcic/dot-ai/issues/255) **Status**: Superseded **Priority**: High **Created**: 2025-12-06 **Closed**: 2025-12-10 --- ## Problem Statement When using the `recommend` tool in capability mode, users can package their AI-generated manifests as Helm charts or Kustomize overlays (PRD #248). However, there's no integration with Argo CD for GitOps deployment: 1. **Manual Application Creation**: Users must manually write Argo CD Application CRs 2. **No Git Integration**: Packaged output isn't automatically pushed to Git repositories 3. **Disconnected Workflow**: The recommend → package → GitOps flow requires manual steps Users following GitOps practices with Argo CD need a seamless path from AI recommendations to GitOps-managed deployments. **Note**: Third-party Helm chart integration with Argo CD is handled separately in PRD #254. --- ## Solution Overview Extend the `recommend` tool's packaging workflow to offer **Argo CD Application generation** after packaging: 1. **Post-Packaging Question**: After generating Helm chart or Kustomize overlay, ask: "Deploy via GitOps?" - No (current behavior - just save packaged output) - Yes, generate Argo CD Application 2. **Git Repository Configuration**: Collect Git repository details for storing packaged output 3. **Application CR Generation**: Create Argo CD Application that references: - For Helm: The Git repo path containing the generated chart - For Kustomize: The Git repo path containing the Kustomize overlay 4. **Output Options**: - Save Application CR alongside packaged output - (Future: Push to Git repository) --- ## User Journeys ### Journey 1: Helm Package → Argo CD ``` User: "Deploy a web application with nginx" → recommend tool generates solution, asks configuration questions → User selects output format: Helm Chart (#248) → System generates Helm chart structure → NEW: "Would you like to deploy via GitOps?" → User selects: Argo CD Application → Additional questions: - Git repository URL for storing the chart? - Path within the repository? - Argo CD Application namespace? (default: argocd) - Sync policy? (Manual / Automatic) → System generates: - Helm chart at specified path - Argo CD Application CR pointing to that path → User gets both outputs ready for Git commit ``` ### Journey 2: Kustomize → Argo CD ``` User: "Deploy a microservice with PostgreSQL" → recommend tool generates solution → User selects output format: Kustomize (#248) → System generates Kustomize overlay structure → NEW: "Would you like to deploy via GitOps?" → User selects: Argo CD Application → Additional questions: - Git repository URL? - Path to kustomization.yaml? - Sync policy? → System generates: - Kustomize files at specified path - Argo CD Application CR with Kustomize source type → User gets both outputs ``` --- ## Technical Design ### Workflow Integration Extend the packaging workflow from #248: ``` [Recommend] → [Package as Helm/Kustomize] → [NEW: GitOps Option] → [Generate Application] → [Save Output] ``` ### GitOps Question (Post-Packaging) ```typescript { id: 'gitopsDeployment', question: 'Would you like to deploy via GitOps?', options: [ { value: 'none', label: 'No', description: 'Just save the packaged output (current behavior)' }, { value: 'argocd', label: 'Argo CD Application', description: 'Generate Application CR for Argo CD deployment' } ], default: 'none', condition: 'outputFormat !== "raw"' // Only show for Helm/Kustomize } ``` ### Argo CD Configuration Questions ```typescript // Git repository details { id: 'gitRepoUrl', question: 'Git repository URL where packaged output will be stored?', type: 'text', placeholder: 'https://github.com/org/gitops-repo.git' }, { id: 'gitRepoPath', question: 'Path within the repository?', type: 'text', placeholder: 'apps/my-application', default: computed from app name }, { id: 'argocdNamespace', question: 'Argo CD Application namespace?', type: 'text', default: 'argocd' }, { id: 'argocdProject', question: 'Argo CD project?', type: 'text', default: 'default' }, { id: 'syncPolicy', question: 'Sync policy?', options: [ { value: 'manual', label: 'Manual' }, { value: 'auto', label: 'Automatic' }, { value: 'auto-prune', label: 'Automatic with Pruning' } ], default: 'manual' } ``` ### Application CR Generation #### For Helm Chart Source ```yaml apiVersion: argoproj.io/v1alpha1 kind: Application metadata: name: my-application namespace: argocd spec: project: default source: repoURL: https://github.com/org/gitops-repo.git path: apps/my-application # Path to Chart.yaml targetRevision: HEAD helm: valueFiles: - values.yaml destination: server: https://kubernetes.default.svc namespace: my-application syncPolicy: automated: prune: true selfHeal: true ``` #### For Kustomize Source ```yaml apiVersion: argoproj.io/v1alpha1 kind: Application metadata: name: my-application namespace: argocd spec: project: default source: repoURL: https://github.com/org/gitops-repo.git path: apps/my-application # Path to kustomization.yaml targetRevision: HEAD destination: server: https://kubernetes.default.svc namespace: my-application syncPolicy: automated: prune: true selfHeal: true ``` ### Output Structure When Argo CD is selected, output directory contains: **For Helm:** ``` <outputPath>/ ├── Chart.yaml ├── values.yaml ├── templates/ │ └── ... └── argocd-application.yaml # NEW: Application CR ``` **For Kustomize:** ``` <outputPath>/ ├── kustomization.yaml ├── base/ │ └── ... └── argocd-application.yaml # NEW: Application CR ``` ### Code Reuse from #254 The Application CR generation logic should be shared with PRD #254: ```typescript // src/core/argocd-generator.ts (from #254) interface ArgoApplicationConfig { name: string; namespace: string; project: string; destination: { server: string; namespace: string }; source: HelmSource | KustomizeSource | HelmRepoSource; syncPolicy?: SyncPolicy; } // Reuse for both: // - #254: HelmRepoSource (external chart repo) // - #255: HelmSource (Git path) or KustomizeSource (Git path) ``` --- ## Success Criteria 1. **Seamless Flow**: Users can go from recommend → package → Argo CD Application in one workflow 2. **Both Package Types**: Works with both Helm and Kustomize output formats 3. **Valid Applications**: Generated Application CRs pass validation 4. **Correct Source Types**: Helm uses helm source config, Kustomize uses directory source 5. **Shared Code**: Application generation logic shared with #254 6. **Backward Compatible**: Users can still skip GitOps integration --- ## Out of Scope 1. **Git Push**: Actually pushing to Git repository (future enhancement) 2. **Third-Party Helm**: Covered by PRD #254 3. **Flux Integration**: Covered by PRD #256 4. **ApplicationSet**: Multi-environment patterns 5. **App of Apps**: Nested Application structures 6. **Private Git Repos**: Credential configuration --- ## Dependencies | PRD | Relationship | |-----|--------------| | **#248** | Required - provides Helm/Kustomize packaging | | **#254** | Related - shares Application generation code | | **#256** | Parallel - Flux equivalent of this PRD | --- ## Risks and Mitigations | Risk | Impact | Mitigation | |------|--------|------------| | Git URL format variations | Application may not sync | Validate URL format, support common patterns | | Path assumptions incorrect | Application points to wrong location | Let user specify exact path | | Sync policy confusion | Unexpected auto-sync behavior | Default to manual, explain options | --- ## Milestones - [ ] **M1**: GitOps deployment question integrated into packaging workflow - [ ] **M2**: Git repository configuration questions working - [ ] **M3**: Application CR generation for Helm chart source - [ ] **M4**: Application CR generation for Kustomize source - [ ] **M5**: Shared code with #254 for Application generation - [ ] **M6**: Integration tests for both Helm and Kustomize paths - [ ] **M7**: Documentation with examples --- ## Progress Log | Date | Update | |------|--------| | 2025-12-06 | PRD created as part of GitOps integration restructuring | | 2025-12-06 | Scoped to packaged output only; third-party Helm in #254 | | 2025-12-10 | PRD superseded by new GitOps architecture | --- ## Closure Summary **Status**: Superseded **Closed**: 2025-12-10 **Reason**: Architectural restructuring This PRD has been superseded by a new GitOps architecture that provides better separation of concerns: - **#264** (GitOps Tool with Argo CD Support): Standalone `gitops` tool with shared infrastructure and pluggable provider architecture - **#265** (Flux Support for GitOps Tool): Adds Flux as a provider - **#266** (GitOps Integration in Recommend Workflow): Integrates gitops into recommend workflow The functionality originally planned in this PRD (Argo CD integration for packaged recommendations) is now covered by #266, which adds an optional `deployViaGitOps` stage to the recommend workflow that delegates to the gitops tool's generator infrastructure.
