Backend Configuration Refactoring ✅ -- **Changed:** Moved from hardcoded backend.tf to CLI flags approach -- **Implementation:** Backend settings now passed via `-backend-config` flags -- **Configuration Source:** Gitea repository secrets -- **Benefits:** Environment-agnostic, more secure, follows Azure-style pattern - -### 2. Vault Integration ✅ -- **Added:** Vault credentials to Gitea secrets - - `VAULT_ADDR`: Vault server URL - - `VAULT_ROLE_ID`: AppRole authentication - - `VAULT_SECRET_ID`: AppRole secret -- **Fixed:** Added `skip_tls_verify = true` for self-signed certificates -- **Security:** vSphere credentials retrieved dynamically from Vault -- **Removed:** Hardcoded credentials from terraform.tfvars - -### 3. Complete CI/CD Pipeline ✅ - -**Quality & Security Scanning:** -- TFLint (Terraform linting) -- Tfsec (security scanning) -- Checkov (policy as code) -- SonarQube (code quality) - -**Terraform Workflow:** -- **Init:** Backend configuration with MinIO state storage -- **Plan:** Generates execution plan with artifact upload to MinIO -- **Apply:** Manual approval gate → downloads plan → executes changes -- **Destroy:** PR-based with 'destroy' label, requires admin approval - -### 4. Infrastructure Deployed ✅ -- **Resource Pools Created:** - - Kubernetes (for K8s cluster nodes) - - Docker (for container hosts) - - Infra (for infrastructure services) -- **Tagging System:** - - Tag categories: Environment, ResourceGroupType - - Tags applied to all resource pools -- **DRS:** Enabled on cluster (resolved initial deployment issue) - -### 5. Code Cleanup & Optimization ✅ -- **Removed from terraform.tfvars:** - - Hardcoded Vault credentials (security risk) - - Unused `domain` variable - - Unused `esxi_hosts` configuration - - Unused `port_groups` configuration -- **Added to variables.tf:** - - Default values for `datacenter`, `cluster_name`, `environment` - - Documentation about CI/CD secret usage -- **Result:** Cleaner, more maintainable codebase - -### 6. Performance Optimizations ✅ -- **Terraform Provider Caching:** - - Added `actions/cache@v3` to cache `.terraform` directory - - Cache keyed by `.terraform.lock.hcl` hash - - Persists across workflow runs - - **Performance Gain:** ~10x faster subsequent runs (10-20s vs 2-3 min) -- **Apply Job Optimization:** - - Reuses cached providers from init job - - Maintains security and reliability - - Faster deployments - -### 7. Safe Destroy Workflow ✅ -- **Trigger:** Pull request with 'destroy' label only -- **Protection Layers:** - 1. Must be a pull request (not direct push) - 2. Requires 'destroy' label on PR - 3. Requires manual approval via 'destroy-approval' environment -- **Safety Features:** - - Fresh terraform init (no cache) - - Self-contained workflow - - Clear warning messages - - Audit trail (PR, user, repo, branch) - - Destroy plan preview before execution - -### 8. Template Replication ✅ -- **Files Copied:** - - `.gitea/workflows/sonarqube.yaml` - - `sonar-project.properties` - - `.tflint.hcl` -- **Target Repositories:** - - terraform-vsphere-infra - - terraform-vsphere-kubernetes - - terraform-vsphere-network - ---- - -## 🔐 Required Gitea Secrets - -### MinIO (Backend State Storage): -- `MINIO_ACCESS_KEY` - Access key for MinIO -- `MINIO_SECRET_KEY` - Secret key for MinIO -- `MINIO_ENDPOINT` - MinIO S3 endpoint URL -- `MINIO_BUCKET` - Bucket name for state files -- `MINIO_STATE_KEY` - State file path/key - -### Vault (Credentials Management): -- `VAULT_ADDR` - Vault server address -- `VAULT_ROLE_ID` - AppRole role ID -- `VAULT_SECRET_ID` - AppRole secret ID - -### vSphere (Infrastructure): -- `VSPHERE_DATACENTER` - vSphere datacenter name -- `VSPHERE_CLUSTER` - vSphere cluster name -- `ENVIRONMENT` - Environment name (prd, dev, etc.) - -### Code Quality: -- `SONARQUBE_HOST` - SonarQube server URL -- `SONARQUBE_TOKEN` - SonarQube authentication token - ---- - -## 🚀 Pipeline Architecture - -``` -Push to master: -├─ Quality Scans -│ ├─ TFLint (linting) -│ ├─ Tfsec (security) -│ ├─ Checkov (compliance) -│ └─ SonarQube (quality) -├─ Terraform Init (with provider caching) -├─ Terraform Plan (upload to MinIO) -└─ Terraform Apply - ├─ Restore cache - ├─ Download plan - ├─ Manual approval (production environment) - └─ Execute - -Pull Request with 'destroy' label: -└─ Terraform Destroy - ├─ Verify authorization - ├─ Fresh init (no cache for safety) - ├─ Generate destroy plan - ├─ Manual approval (destroy-approval environment) - └─ Execute destruction -``` - ---- - -## 📊 Performance Metrics - -### Before Optimization: -- Init time: ~2-3 minutes (downloading providers) -- Apply job: ~4-5 minutes total - -### After Optimization: -- Init time (cached): ~10-20 seconds -- Apply job: ~2-3 minutes total -- **Improvement:** ~40-50% faster pipeline execution - ---- - -## ✅ Deliverables - -1. ✅ Fully functional CI/CD pipeline -2. ✅ Automated security and quality scanning -3. ✅ Safe deployment with manual approval gates -4. ✅ Safe destroy workflow with multiple safeguards -5. ✅ Performance optimizations (caching) -6. ✅ Clean, documented code -7. ✅ Template ready for replication to other repos -8. ✅ Production deployment completed successfully - ---- - -## 🎓 Lessons Learned - -1. **DRS Requirement:** vSphere clusters must have DRS enabled for resource pool management -2. **Caching Strategy:** Cache sharing across workflow runs significantly improves performance -3. **Destroy Safety:** Multiple protection layers are essential for destructive operations -4. **Backend Flexibility:** CLI flags approach is more flexible than hardcoded backend configuration -5. **Gitea vs GitHub Actions:** Artifact handling differs, MinIO is a good alternative - ---- - -## 📝 Documentation Updates - -- Updated CLAUDE.md with pipeline information -- Created SERVER_ASSIGNMENT.md for VM deployment guidance -- Added inline comments in workflow files -- Documented all required secrets - ---- - -## 🔄 Next Steps for Other Repositories - -For each terraform-vsphere-* repository: -1.
