Summary

This PR addresses critical template issues and adds comprehensive CI/CD validation to prevent similar issues in the future.

Problem

GitHub issue #61 identified a critical bug where malformed YAML in Helm templates caused deployment failures when Redis was disabled (the default configuration). The workflow also lacked automated validation to catch such issues before merge.

✨ New Features

3. Helm Lint Workflow (.github/workflows/helm-lint.yml)

Triggers:

• ✅ Pull requests to main or gh-pages (auto-run on chart changes)
• ✅ When helm-lint label is added to PR
• ✅ Weekly schedule (Mondays 9 AM UTC)
• ✅ Manual dispatch via GitHub Actions UI

Validation Steps:

1. Helm Lint (Strict Mode) - Validates chart syntax and structure
2. Dry-Run Deployment - Simulates deployment to catch configuration issues
3. Template Rendering - Verifies all templates render without errors

Branch Support:

• Automatically detects chart location (main: charts/tooljet/, gh-pages: root)
• Works with both branch structures seamlessly

4. Real Deployment Testing Workflow (.github/workflows/helm-deploy-test.yml)

Triggers:

• ⏰ Weekly (Mondays 10 AM UTC)
• 🔧 Manual dispatch

Testing:

• Creates a real Kubernetes cluster using Kind
• Deploys the chart with PostgreSQL enabled
• Verifies pods start successfully
• Provides deployment logs for debugging

Benefits

Immediate

• ✅ Fixes deployment failures affecting all default installations
• ✅ Prevents PRs with template errors from being merged
• ✅ Catches configuration issues before they reach production

Long-term

• 🛡️ Automated quality gates for all chart changes
• 🚀 Fast feedback on PRs (~15 seconds added to CI)
• 📊 Weekly verification of chart deployability
• 🔍 Catches issues that linting alone misses

Testing

Local Validation ✅

• helm lint charts/tooljet --strict - PASSED
• helm install --dry-run - PASSED
• helm template - PASSED (668 lines rendered)

Workflows Tested ✅

• Dry-run deployment validation works correctly
• Template rendering completes successfully
• Chart path detection works for both main and gh-pages branches
