ARC Config MCP Server

# Code Change Required: hybrid-tools.ts **File**: `src/tools/hybrid-tools.ts` **Lines**: 102-119 **Priority**: High - Direct user experience impact ## Current Code (To Replace) ```typescript } else { response += '## 📋 Step 3: Configuration Generated (Not Applied)\n\n'; response += `⚠️ **Configuration generated but NOT applied to cluster** (--apply false)\n\n`; response += `### To install the ARC controller:\n\n`; response += `**Option 1: Use the apply tool**\n`; response += `\`\`\`\n`; response += `#arc_apply_config --configType controller\n`; response += `\`\`\`\n\n`; response += `**Option 2: Install manually with Helm**\n`; response += `\`\`\`bash\n`; response += `helm install arc-controller \\\n`; response += ` oci://ghcr.io/actions/actions-runner-controller-charts/gha-runner-scale-set-controller \\\n`; response += ` --namespace ${namespace} \\\n`; response += ` --create-namespace`; if (version !== 'latest') { response += ` \\\n --version ${version}`; } response += `\n\`\`\`\n\n`; response += `💾 **Configuration saved** at \`${result.configPath}\` for review and version control.\n`; } ``` ## New Code (To Implement) ```typescript } else { response += '## 📋 Step 3: Configuration Generated (Not Applied)\n\n'; response += `⚠️ **Configuration generated but NOT applied to cluster** (--apply false)\n\n`; response += `### 📄 What was created?\n\n`; response += `The configuration file at \`${result.configPath}\` contains:\n`; response += `- **Chart information**: Repository URL and version\n`; response += `- **Release details**: Name and namespace\n`; response += `- **Helm values**: Custom configuration (currently empty, but you can add values)\n\n`; response += `### 🔄 How to apply:\n\n`; response += `**Option 1: Use the apply tool (Recommended)**\n`; response += `\`\`\`\n`; response += `#arc_apply_config --configType controller\n`; response += `\`\`\`\n`; response += `This command reads your config file and executes:\n`; response += `\`\`\`bash\n`; response += `helm upgrade arc-controller \\\n`; response += ` oci://ghcr.io/actions/actions-runner-controller-charts/gha-runner-scale-set-controller \\\n`; response += ` --install \\\n`; response += ` --namespace ${namespace} \\\n`; response += ` --create-namespace`; if (version !== 'latest') { response += ` \\\n --version ${version}`; } response += `\n # Plus any --set flags from the values section\n`; response += `\`\`\`\n\n`; response += `**Option 2: Manual installation (bypasses config file)**\n`; response += `If you want to install without using the generated config:\n`; response += `\`\`\`bash\n`; response += `helm install arc-controller \\\n`; response += ` oci://ghcr.io/actions/actions-runner-controller-charts/gha-runner-scale-set-controller \\\n`; response += ` --namespace ${namespace} \\\n`; response += ` --create-namespace`; if (version !== 'latest') { response += ` \\\n --version ${version}`; } response += `\n\`\`\`\n`; response += `⚠️ **Note**: This uses default settings and ignores any custom values in your config file.\n\n`; response += `💡 **Tip**: You can edit \`${result.configPath}\` to add custom Helm values before applying.\n`; } ``` ## What Changed? ### 1. Added "What was created?" Section **Before**: No explanation of config file contents **After**: Clear bullet points explaining what's in the file ```diff + ### 📄 What was created? + + The configuration file at `${result.configPath}` contains: + - **Chart information**: Repository URL and version + - **Release details**: Name and namespace + - **Helm values**: Custom configuration (currently empty, but you can add values) ``` ### 2. Renamed and Enhanced "Option 1" **Before**: "Use the apply tool" **After**: "Use the apply tool (Recommended)" + explains what it does ```diff - **Option 1: Use the apply tool** + **Option 1: Use the apply tool (Recommended)** ``` #arc_apply_config --configType controller ``` + This command reads your config file and executes: + ```bash + helm upgrade arc-controller \ + oci://ghcr.io/.../gha-runner-scale-set-controller \ + --install \ + --namespace arc-systems \ + --create-namespace + # Plus any --set flags from the values section + ``` ``` **Key Addition**: Shows the actual Helm command that will be executed ### 3. Clarified "Option 2" - Manual Installation **Before**: Implied this uses the config file **After**: Explicitly states it bypasses the config ```diff - **Option 2: Install manually with Helm** + **Option 2: Manual installation (bypasses config file)** + If you want to install without using the generated config: ```bash helm install arc-controller \ oci://ghcr.io/.../gha-runner-scale-set-controller \ --namespace arc-systems \ --create-namespace ``` + ⚠️ **Note**: This uses default settings and ignores any custom values in your config file. ``` **Key Addition**: Warning that this bypasses the config ### 4. Enhanced Final Tip **Before**: Generic "Configuration saved" message **After**: Actionable tip about editing the config ```diff - 💾 **Configuration saved** at `${result.configPath}` for review and version control. + 💡 **Tip**: You can edit `${result.configPath}` to add custom Helm values before applying. ``` ## Why These Changes Matter ### Before (Problems): 1. ❌ Users confused about whether manual Helm command uses config file 2. ❌ No explanation of what's in the config file 3. ❌ No visibility into what `#arc_apply_config` actually does 4. ❌ "Option 2" implies it's equivalent to Option 1 ### After (Solutions): 1. ✅ Clear that Option 1 uses config, Option 2 bypasses it 2. ✅ Users understand config file structure 3. ✅ Transparency: Shows the actual Helm command that will run 4. ✅ Encourages customization with the "Tip" ## Testing After Implementation ### Test 1: Generate Config ```bash #arc_install_controller_hybrid --apply false ``` **Expected Output**: - ✅ Shows "What was created?" section - ✅ Option 1 explains it reads the config - ✅ Shows the actual Helm command - ✅ Option 2 warns it bypasses config - ✅ Tip suggests editing the config ### Test 2: Verify Config File ```bash cat configs/controller.yaml ``` **Expected**: - ✅ File contains chart, release, values, metadata sections - ✅ Values section is empty `{}` ### Test 3: Edit and Apply ```bash # Edit configs/controller.yaml - add: # values: # replicaCount: 2 #arc_apply_config --configType controller ``` **Expected**: - ✅ Shows Helm command with `--set replicaCount=2` - ✅ Applies successfully ## Implementation Steps 1. **Backup the file**: ```bash cp src/tools/hybrid-tools.ts src/tools/hybrid-tools.ts.backup ``` 2. **Open in editor**: ```bash code src/tools/hybrid-tools.ts ``` 3. **Navigate to lines 102-119** 4. **Replace the `else` block** with the new code above 5. **Save the file** 6. **Rebuild**: ```bash npm run build ``` 7. **Rebuild Docker image**: ```bash ./build-local.sh ``` 8. **Test**: ```bash #arc_install_controller_hybrid --apply false ``` ## Success Criteria After implementing this change, users should: - ✅ Understand what the config file contains - ✅ Know that Option 1 uses the config, Option 2 doesn't - ✅ See the actual Helm command that will be executed - ✅ Be encouraged to customize the config file - ✅ Feel confident about what's happening ## Related Files This change complements: - `docs/HYBRID_WORKFLOW_CLARITY.md` - Full explanation - `examples/controller-with-values.yaml.md` - Configuration examples - `docs/HYBRID_WORKFLOW_VISUAL_GUIDE.md` - Visual workflow - `src/services/hybrid-deployment.ts` - Enhanced comments --- **Status**: Ready to implement - All documentation is in place, just needs this one code change!
