16. CI/CD Pipeline Design for Multi-Platform Compatibility

Date: 2026-04-05 Status: 🟡 Proposed Authors: Arcodange Team Decision Date: TBD Implementation Status: Not Started

Context

DanceLessonsCoach requires a robust CI/CD pipeline that:

  1. Primary Platform: Gitea (self-hosted Git service)
  2. Mirror Support: GitHub and GitLab mirrors for visibility and backup
  3. Tool Agnostic: Easy migration between CI/CD platforms
  4. Feature Requirements:
    • Automated builds and testing
    • Version management and changelog generation
    • Code quality checks (linting, formatting)
    • Status badges for README
    • Artifact publishing
    • Deployment capabilities

Decision Drivers

  • Gitea Compatibility: Must work with Gitea's CI/CD capabilities
  • GitHub Actions Compatibility: Leverage widely-known workflow syntax
  • GitLab CI Compatibility: Support GitLab's pipeline format
  • Portability: Easy migration between platforms
  • Open Source Friendly: Use tools that work well with open source projects
  • Minimal Vendor Lock-in: Avoid platform-specific features when possible
  • Badges & Status: Visual indicators of build/test status
  • Code Quality: Automated linting and formatting checks
  • Version Management: Automatic version bumping based on conventional commits
  • Artifact Publishing: Binary releases and container images
  • Mirror Sync: Ensure mirrors stay in sync with CI/CD results

Decision

We will implement a multi-platform compatible CI/CD pipeline using GitHub Actions workflow syntax as the common denominator, with platform-specific adapters where needed.

Selected Architecture: Portable Workflow Design

Pipeline Components

1. Core Workflow (GitHub Actions YAML)

  • File: .github/workflows/main.yml (works on all platforms)
  • Format: Standard GitHub Actions workflow syntax
  • Benefits: Widely understood, well-documented, portable

2. Platform Adapters

  • Gitea: Native support for GitHub Actions workflows
  • GitHub: Native support (no adapter needed)
  • GitLab: Use github-actions-importer or manual conversion

3. Workflow Structure

[![Pipeline](https://gitea.arcodange.fr/api/badges/arcodange/DanceLessonsCoach/pipeline.svg)](https://gitea.arcodange.fr/arcodange/DanceLessonsCoach/-/pipelines)

Configuration Details:

5. Configure CI/CD runners on internal network

- Set up runners to access: https://gitea.arcodange.lab/

- Configure SSH access: ssh://git@192.168.1.202:2222/arcodange/DanceLessonsCoach.git

- Ensure runners have network access to internal services (192.168.1.202:2222)

- Configure runners with proper GITEA_TOKEN

- Test connection: curl https://gitea.arcodange.lab/api/v1/version


### Phase 2: Linting and Quality (Week 2)
```bash
# 1. Add golangci-lint configuration
cat > .golangci.yml << 'EOF'
run:
  timeout: 5m
  issues-exit-code: 1
  tests: false

linters:
  enable:
    - errcheck
    - gofmt
    - goimports
    - gosimple
    - govet
    - ineffassign
    - staticcheck
    - unused
EOF

# 2. Update workflow to include linting
cat >> .github/workflows/main.yml << 'EOF'
  lint:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-go@v4
        with:
          go-version: '1.26.1'
      - uses: golangci/golangci-lint-action@v3
        with:
          version: v1.55
EOF

# 3. Add pre-commit hooks
cat > .pre-commit-config.yaml << 'EOF'
repos:
  - repo: https://github.com/golangci/golangci-lint
    rev: v1.55.2
    hooks:
      - id: golangci-lint
  - repo: https://github.com/pre-commit/pre-commit-hooks
    rev: v4.4.0
    hooks:
      - id: trailing-whitespace
      - id: end-of-file-fixer
      - id: check-yaml
EOF

Phase 3: Version Management (Week 3)

# 1. Enhance version-bump.sh for auto-detection
cat > scripts/version-bump-auto.sh << 'EOF'
#!/bin/bash
# Auto-detect version bump based on conventional commits

# Get last commit message
LAST_COMMIT=$(git log -1 --pretty=%B)

if echo "$LAST_COMMIT" | grep -q "^feat:"; then
    echo "📋 Detected feature commit, bumping MINOR version"
    ./scripts/version-bump.sh minor
elif echo "$LAST_COMMIT" | grep -q "^fix:"; then
    echo "🐛 Detected fix commit, bumping PATCH version"
    ./scripts/version-bump.sh patch
elif echo "$LAST_COMMIT" | grep -q "BREAKING CHANGE"; then
    echo "💥 Detected breaking change, bumping MAJOR version"
    ./scripts/version-bump.sh major
else
    echo "⏭️  No version bump needed for this commit type"
fi
EOF

# 2. Add version management to workflow
# 3. Create CHANGELOG.md auto-generation

Phase 4: Badges and Status (Week 4)

# 1. Add badge documentation
cat > STATUS_BADGES.md << 'EOF'
# CI/CD Status Badges

## Gitea (Primary)
```markdown
[![Build Status](https://ci.your-gitea-instance.com/api/badges/project/status)](https://ci.your-gitea-instance.com)

2. Add badges to README.md

3. Set up external badge services


### Phase 5: Mirror CI/CD Setup (Optional)
```bash
# For GitHub Mirror:
# 1. Enable GitHub Actions on the mirror repo
# 2. Use the same .github/workflows/main.yml
# 3. Configure mirror to not trigger builds on mirror pushes

# For GitLab Mirror:
# 1. Create .gitlab-ci.yml that imports GitHub Actions
# 2. Or manually convert workflow to GitLab CI syntax
# 3. Configure mirror to not trigger duplicate builds

Pros and Cons of Selected Approach

Advantages

  1. Portability: GitHub Actions YAML works on Gitea and GitHub natively
  2. Familiarity: Most developers know GitHub Actions syntax
  3. Documentation: Excellent GitHub Actions documentation available
  4. Marketplace: Access to GitHub Actions marketplace actions
  5. Mirror Compatibility: Same workflow files work on mirrors
  6. Tool Agnostic: Can convert to other formats if needed
  7. Badges: Easy to generate status badges for all platforms
  8. Extensible: Can add more jobs/stages as needed

Disadvantages

  1. GitLab Conversion: May need manual conversion for GitLab CI
  2. Vendor Features: Some GitHub-specific features won't work on Gitea
  3. Learning Curve: Team needs to learn GitHub Actions syntax
  4. Mirror Complexity: Need to prevent duplicate builds on mirrors
  5. Badge Management: Multiple badge URLs to maintain

Validation

Does this meet our requirements?

  • Gitea Compatibility: Uses Gitea's GitHub Actions support
  • GitHub Mirror: Native GitHub Actions support
  • GitLab Mirror: Can use conversion tools or manual setup
  • Portability: Common workflow format across platforms
  • Badges: Status badges for all platforms
  • Linting: Integrated code quality checks
  • Version Management: Automatic version bumping
  • Artifacts: Binary releases and publishing

What's still needed?

  • Implementation: Actual CI/CD pipeline setup
  • Gitea Configuration: CI/CD runner setup on Gitea instance
  • Mirror Configuration: Prevent duplicate builds
  • Badge Services: Set up external badge providers
  • Testing: Validate pipeline works on all platforms
  • Documentation: Complete CI/CD setup guide

🐳 Docker-Based Local Testing (Primary Method)

Arcodange uses Docker as the primary method for local CI/CD testing.

Comprehensive Testing Script

Use the provided script for complete Docker-based testing:

# Run complete CI/CD test suite
./scripts/test-cicd-docker.sh

What the script does:

  1. Checks Docker availability
  2. Pulls required Docker images
  3. Validates YAML syntax with yq
  4. Lints YAML with yamllint
  5. Executes workflow with act runner
  6. Reports success/failure

Manual Docker Testing

For more control, run individual Docker commands:

# 1. Validate YAML syntax
docker run --rm \
  -v $(pwd):/workspace \
  -w /workspace \
  mikefarah/yq:latest \
  yq eval '.' .gitea/workflows/ci-cd.yaml

# 2. Lint YAML
docker run --rm \
  -v $(pwd):/workspace \
  -w /workspace \
  cybertanium/yamllint:latest \
  yamllint .gitea/workflows/

# 3. Run workflow with Arcodange environment
docker run --rm \
  -v $(pwd):/workspace \
  -w /workspace \
  -e GITEA_INTERNAL="https://gitea.arcodange.lab/" \
  -e GITEA_EXTERNAL="https://gitea.arcodange.fr/" \
  -e GITEA_ORG="arcodange" \
  -e GITEA_REPO="DanceLessonsCoach" \
  gitea/act_runner:latest \
  act -W .gitea/workflows/ci-cd.yaml --rm

Alternative: Using nektos/act for GitHub Actions Compatibility

# 1. Install act (GitHub Actions runner)
brew install act

# 2. Run workflow locally
act -W .gitea/workflows/ci-cd.yaml \
  --secret-file .secrets \
  --env-file .env \
  --container-architecture linux/amd64

# 3. With specific event simulation
act push -W .gitea/workflows/ci-cd.yaml \
  --env GITEA_ORG=arcodange \
  --env GITEA_REPO=DanceLessonsCoach

Pipeline Status Checking Scripts
