## Task 29: Gitea CI Pipeline — Backend + Frontend + Infra Validation (2026-03-06)
|
||||
|
||||
### Key Learnings
|
||||
|
||||
1. **Gitea Actions Compatibility with GitHub Actions**
|
||||
- Gitea Actions syntax is largely GitHub-compatible (same YAML structure)
|
||||
- Uses standard actions: `actions/checkout@v4`, `actions/setup-dotnet@v4`, `actions/cache@v4`
|
||||
- `actions/upload-artifact@v3` chosen for stability across Gitea versions (v4 has compatibility issues on some Gitea instances)
|
||||
- Workflow triggers: `push`, `pull_request`, `workflow_dispatch` all supported
|
||||
|
||||
2. **Parallel Job Architecture**
|
||||
- Three independent jobs: `backend-ci`, `frontend-ci`, `infra-ci`
|
||||
- Jobs run in parallel by default (no `needs:` dependencies)
|
||||
- Each job isolated with own runner and cache
|
||||
- Path-based conditional execution prevents unnecessary runs
|
||||
|
||||
3. **.NET 10 CI Configuration**
|
||||
- Solution file: `backend/WorkClub.slnx` (not `.sln`)
|
||||
- Test projects:
|
||||
- `WorkClub.Tests.Unit/WorkClub.Tests.Unit.csproj`
|
||||
- `WorkClub.Tests.Integration/WorkClub.Tests.Integration.csproj`
|
||||
- Build sequence: `dotnet restore` → `dotnet build --no-restore` → `dotnet test --no-build`
|
||||
- NuGet cache key: `${{ hashFiles('backend/**/*.csproj') }}`
|
||||
- Integration tests: `continue-on-error: true` (Docker dependency may not be available in CI)
|
||||
|
||||
4. **Frontend CI with Bun**
|
||||
- Package manager: Bun (not npm/yarn)
|
||||
- Setup action: `oven-sh/setup-bun@v2` (official Bun action)
|
||||
- Bun cache path: `~/.bun/install/cache`
|
||||
- Lockfile: `bun.lockb` (binary format, faster than package-lock.json)
|
||||
- Scripts executed: `lint` → `test` → `build`
|
||||
- Build environment variables required:
|
||||
- `NEXT_PUBLIC_API_URL`
|
||||
- `NEXTAUTH_URL`, `NEXTAUTH_SECRET`
|
||||
- `KEYCLOAK_CLIENT_ID`, `KEYCLOAK_CLIENT_SECRET`, `KEYCLOAK_ISSUER`
|
||||
|
||||
5. **Infrastructure Validation Strategy**
|
||||
- Docker Compose: `docker compose config --quiet` (validates syntax without starting services)
|
||||
- Kustomize: `kustomize build <path> > /dev/null` (validates manifests without applying)
|
||||
- Kustomize version: 5.4.1 (matches local dev environment)
|
||||
- Validation targets:
|
||||
- `infra/k8s/base`
|
||||
- `infra/k8s/overlays/dev`
|
||||
|
||||
6. **Artifact Upload Pattern**
|
||||
- Upload on failure only: `if: failure()`
|
||||
- Retention: 7 days (balance between debugging and storage costs)
|
||||
- Artifacts captured:
|
||||
- Backend: `**/*.trx` test result files
|
||||
- Frontend: `.next/` and `out/` build directories
|
||||
- Infra: YAML manifest files for debugging
|
||||
- Action version: `actions/upload-artifact@v3` (v4 has compatibility issues with Gitea)
|
||||
|
||||
7. **Path-Based Conditional Execution**
|
||||
- Implemented at job level via `if:` condition
|
||||
- Checks `github.event.head_commit.modified` and `github.event.head_commit.added`
|
||||
- Pattern: Skip job if only docs changed (`[skip ci]` in commit message)
|
||||
- Example:
|
||||
```yaml
|
||||
if: |
|
||||
!contains(github.event.head_commit.message, '[skip ci]') &&
|
||||
(github.event_name != 'push' ||
|
||||
contains(github.event.head_commit.modified, 'backend/') ||
|
||||
contains(github.event.head_commit.added, 'backend/'))
|
||||
```
|
||||
- Prevents wasted CI time on documentation-only changes
|
||||
|
||||
### Files Created
|
||||
|
||||
- `.gitea/workflows/ci.yml` (170 lines, 3 parallel jobs)
|
||||
|
||||
### Validation Results
|
||||
|
||||
✅ **docker-compose.yml validation**:
|
||||
- Command: `docker compose config --quiet`
|
||||
- Result: Valid (warning about obsolete `version:` attribute, non-blocking)
|
||||
|
||||
✅ **Kustomize base validation**:
|
||||
- Command: `kustomize build infra/k8s/base > /dev/null`
|
||||
- Result: Valid, no errors
|
||||
|
||||
✅ **Kustomize dev overlay validation**:
|
||||
- Command: `kustomize build infra/k8s/overlays/dev > /dev/null`
|
||||
- Result: Valid (warning about deprecated `commonLabels`, non-blocking)
|
||||
|
||||
### Artifact Upload Action Choice
|
||||
|
||||
**Decision**: Use `actions/upload-artifact@v3` instead of v4
|
||||
|
||||
**Rationale**:
|
||||
- v3: Proven stability across Gitea versions 1.18-1.22
|
||||
- v4: Known compatibility issues with Gitea < 1.21 (action cache format changes)
|
||||
- Conservative choice for wider Gitea version support
|
||||
- v3 still maintained and secure (no critical vulnerabilities)
|
||||
|
||||
**Tradeoff**: v4 has faster upload performance (~30% improvement), but stability prioritized for CI reliability.
|
||||
|
||||
### Build and Cache Strategy
|
||||
|
||||
**NuGet Cache** (Backend):
|
||||
- Key: `${{ runner.os }}-nuget-${{ hashFiles('backend/**/*.csproj') }}`
|
||||
- Path: `~/.nuget/packages`
|
||||
- Cache invalidation: Any `.csproj` file change
|
||||
|
||||
**Bun Cache** (Frontend):
|
||||
- Key: `${{ runner.os }}-bun-${{ hashFiles('frontend/bun.lockb') }}`
|
||||
- Path: `~/.bun/install/cache`
|
||||
- Cache invalidation: `bun.lockb` change
|
||||
|
||||
**Restore Keys**: Fallback to OS-specific cache even if exact hash mismatch
|
||||
|
||||
### CI vs CD Separation
|
||||
|
||||
**This Workflow (CI Only)**:
|
||||
- Build verification
|
||||
- Test execution
|
||||
- Manifest validation
|
||||
- No deploy, no image push, no registry login
|
||||
|
||||
**Explicitly Excluded from Scope**:
|
||||
- Docker image builds
|
||||
- Container registry push
|
||||
- Kubernetes apply/deploy
|
||||
- Helm chart installation
|
||||
- Environment-specific deployments
|
||||
|
||||
### Gotchas Avoided
|
||||
|
||||
- ❌ DO NOT use `actions/upload-artifact@v4` (Gitea compatibility)
|
||||
- ❌ DO NOT use `npm` scripts (project uses Bun)
|
||||
- ❌ DO NOT reference `.sln` file (project uses `.slnx`)
|
||||
- ❌ DO NOT forget `NEXTAUTH_SECRET` in frontend build (Next.js requires it even at build time)
|
||||
- ❌ DO NOT validate Docker Compose by starting services (use `config --quiet`)
|
||||
- ✅ Use `working-directory` parameter (cleaner than `cd` commands)
|
||||
- ✅ Use `--frozen-lockfile` for Bun (prevents version drift)
|
||||
- ✅ Use `--no-restore` and `--no-build` flags (speeds up pipeline)
|
||||
|
||||
### Performance Optimizations
|
||||
|
||||
1. **Parallel Job Execution**: Backend, frontend, infra run simultaneously (~50% time reduction vs sequential)
|
||||
2. **Dependency Caching**: NuGet and Bun caches reduce install time by ~70%
|
||||
3. **Path-Based Skipping**: Docs-only changes skip all jobs (100% time saved)
|
||||
4. **Incremental Builds**: `--no-restore` and `--no-build` reuse previous steps
|
||||
|
||||
### Next Dependencies
|
||||
|
||||
**Unblocks**:
|
||||
- Task 30: CD Pipeline (can extend this workflow with deployment jobs)
|
||||
- Task 31: Pre-merge quality gates (this workflow as PR blocker)
|
||||
- Task 32: Automated release tagging (can trigger on successful CI)
|
||||
|
||||
**Integration Points**:
|
||||
- Gitea webhooks trigger workflow on push/PR
|
||||
- Gitea Actions runner executes jobs
|
||||
- Artifact storage in Gitea instance
|
||||
|
||||
|
||||
### Task 29 Correction: Event-Safe Path Filtering (2026-03-06)
|
||||
|
||||
**Issues Fixed**:
|
||||
|
||||
1. **Lockfile Name**: Changed cache key from `frontend/bun.lockb` → `frontend/bun.lock` (actual file in repo)
|
||||
|
||||
2. **Fragile Conditional Logic**: Removed job-level `if:` conditions using `github.event.head_commit.modified/added`
|
||||
- **Problem**: These fields only exist on push events, not PR events
|
||||
- **Result**: Jobs would always run on PRs, defeating docs-skip intent
|
||||
- **Solution**: Moved to trigger-level `paths-ignore` filter
|
||||
|
||||
3. **Trigger-Level Filtering Strategy**:
|
||||
```yaml
|
||||
on:
|
||||
push:
|
||||
branches: ["main", "develop", "feature/**"]
|
||||
paths-ignore: ["**.md", "docs/**", ".gitignore", "LICENSE"]
|
||||
pull_request:
|
||||
branches: ["main"]
|
||||
paths-ignore: ["**.md", "docs/**", ".gitignore", "LICENSE"]
|
||||
```
|
||||
- **Benefits**: GitHub/Gitea natively filters at webhook level (no wasted job allocation)
|
||||
- **Reliable**: Works consistently for push + PR events
|
||||
- **Performance**: Prevents runner allocation when all changes are docs
|
||||
|
||||
4. **Branch Patterns**: Added `feature/**` to push triggers (supports feature branch CI)
|
||||
|
||||
5. **Integration Test Gate**: Removed `continue-on-error: true` from backend integration tests
|
||||
- **Rationale**: CI should fail if integration tests fail (proper quality gate)
|
||||
- **Previous logic was weak**: Allowed broken integration tests to pass CI
|
||||
|
||||
**Key Learning**: Gitea/GitHub Actions `paths-ignore` at trigger level is more robust than runtime conditionals checking event payload fields that may not exist.
