Summary

This PR establishes comprehensive testing and validation infrastructure for the Jellyfin Helm chart:

  • 603 helm-unittest tests - 100% pass rate (20 test suites)
  • PR checks workflow - 7 automated validations for all PRs
  • Template improvements - conditional rendering and enhanced logic
  • CI configuration - yamllint, markdownlint, chart-testing configs

Changes

1. Test Suite Fixes (603 tests, 100% passing)

Fixed all helm-unittest test failures by addressing:

  • Volume contains assertions now include full object structure (PVC, hostPath with type: Directory, emptyDir)
  • ServiceMonitor uses port name "http" instead of numeric port
  • NetworkPolicy port references and egress rule structure corrections
  • Image tag tests use semver regex pattern instead of hardcoded versions
  • dnsPolicy path handling (only exists when explicitly set)
  • documentIndex placement corrected to test level
  • Empty array assertions use lengthEqual count:0 instead of isNull
  • Deployment annotations validate specific values

2. PR Checks Workflow

Added .github/workflows/pr-checks.yaml with 7 essential validations:

  1. helm-docs diff check - ensures README.md is regenerated after values.yaml changes
  2. helm-unittest - runs all 603 tests
  3. helm lint - includes values.schema.json validation
  4. helm template - validates manifest generation
  5. chart-testing (ct lint) - YAML lint, version check, best practices
  6. kubeconform - validates K8s manifests against versions 1.29-1.31
  7. markdownlint - validates markdown documentation

All actions use pinned SHA versions for security.

3. Template Improvements

deployment.yaml enhancements:

  • Added conditional rendering for podSecurityContext, securityContext, resources
  • Improved dnsPolicy logic with automatic ClusterFirstWithHostNet fallback for DLNA/hostNetwork
  • Fixed revisionHistoryLimit to handle zero values correctly (allows disabling revision history)

4. CI Configuration Files

  • ct.yaml - chart-testing configuration
  • .yamllint.yaml - YAML linting rules (ignores templates/ and .github/ directories)
  • .markdownlint.yaml - markdown linting rules

5. Linting Fixes

  • Removed trailing spaces from values.yaml
  • Regenerated README.md with helm-docs
  • Updated yamllint config to ignore Helm templates (Go template syntax conflicts with YAML parser)

Testing

Local validation completed successfully:

✅ helm-docs: README synchronized
✅ helm-unittest: 603/603 tests passing
✅ helm lint: validation passed (including schema)
✅ helm template: generation successful
✅ yamllint: no critical errors

Breaking Changes

None. All changes are backwards compatible.

Fix duplicate description field in NetworkPolicy/inotify changelog entries.
The changelog had two description fields in one entry which is invalid YAML.
Split into two separate changelog items.

…validation

Add values.schema.json with comprehensive validation for chart values:
- All core fields with types, defaults, and enums
- Validation preventing NetworkPolicy + hostNetwork conflicts
- Validation preventing NetworkPolicy + DLNA conflicts

The schema uses JSON Schema draft-07 with allOf/if-then logic to enforce
mutual exclusivity: networkPolicy.enabled cannot be true when either
jellyfin.enableDLNA or podPrivileges.hostNetwork is true.

Validated with check-jsonschema against current values.yaml and
test cases for both valid and invalid configurations.

…detailed documentation

Significantly improve values.schema.json:

- Add enums for all constrained values (pullPolicy, service.type, dnsPolicy,
  deploymentStrategy, ipFamilyPolicy, pathType, persistence.type, accessMode)
- Add regex patterns for Kubernetes-specific formats (size, CIDR, intervals)
- Add port range validation (1-65535, nodePort 30000-32767)
- Add hostname format validation for Ingress/HTTPRoute
- Add required fields for arrays (env.name, imagePullSecrets.name)
- Add detailed structure for envFrom, env, imagePullSecrets
- Add comprehensive descriptions for every field with defaults and examples
- Add uniqueItems, minItems, maxItems constraints where applicable

Validated against:
- Invalid size patterns (rejects non-Kubernetes formats)
- Invalid enums (rejects 'nfs' for persistence.type)
- Invalid CIDR notation (IPv4/IPv6 regex)
- Mutual exclusivity (NetworkPolicy vs hostNetwork/DLNA)

- Keep access instructions based on service type
- Keep persistence warnings
- Remove excessive details about features
- Replace emoji with ASCII (*** WARNING ***, *** ERROR ***) to maintain monospace alignment
- Ensure all banner lines are exactly 77 characters

Phase 1: Improve and expand existing test coverage with edge cases,
validations, and regression tests.

Changes:
- Rename cache_persistence_test → persistence_test with full coverage
  for config, media, and cache persistence (60+ tests)

…ervicemonitor, security, scheduling)

Phase 2: Create comprehensive tests for critical resources that had no
coverage previously.

New test files:
- ingress_test.yaml: Full ingress coverage including className, annotations,
  hosts, paths, pathTypes, TLS, edge cases (70+ tests)

Phase 4: Create integration tests for real-world scenarios and regression
tests to lock down all default values.

New test files:
- integration_common_configs_test.yaml: 12 real-world deployment scenarios
  including DLNA home server, secure production, Prometheus monitoring,
  IPv6-only/dual-stack, cloud providers (AWS IRSA, GCP WI), air-gapped,
  minimal resource-constrained, Gateway API HTTPRoute (50+ tests)
- regression_defaults_test.yaml: Comprehensive verification of all default
  values across all resources to prevent accidental changes. Covers
  deployment, service, serviceAccount, persistence, probes, labels,

Integration scenarios tested:
1. DLNA Home Media Server (hostNetwork, NodePort, NAS storage)
2. Secure Production (NetworkPolicy, security contexts, resources, ingress+TLS)
3. Kubernetes with Prometheus (metrics, ServiceMonitor, custom NetworkPolicy)
4. IPv6-only cluster (SingleStack IPv6)
5. Dual-stack networking (IPv4+IPv6, LoadBalancer)
6. Development environment (emptyDir, latest tag, debug logging)
7. High Availability attempt (multiple replicas, ReadWriteMany, pod anti-affinity)
8. AWS with IRSA (EKS role annotations, gp3 storage, NLB, ALB ingress)
9. GCP with Workload Identity (GKE service account annotations)
10. Air-gapped environment (private registry, restrictive NetworkPolicy)
11. Minimal resource-constrained (low CPU/memory limits, emptyDir)
12. Gateway API (HTTPRoute with multiple hostnames)

Regression tests lock down:
- All default values: replicas=1, revisionHistoryLimit=3, ClusterIP service,
  port 8096, IfNotPresent pullPolicy, ClusterFirst dnsPolicy
- Persistence defaults: config 5Gi, media 25Gi, cache emptyDir
- Probe defaults: startup (tcpSocket, 0/10/30), liveness/readiness (httpGet)
- Feature flags: DLNA off, metrics off, NetworkPolicy off, ServiceMonitor off
- API versions and naming patterns
- Critical invariants that must never change

Total: 2 new test files, 130+ new test cases

Fixed yamllint configuration and values.yaml issues:
- Added ignore patterns for templates/ and .github/ directories to yamllint config
  (Helm templates contain Go template syntax that conflicts with YAML syntax)
- Removed trailing spaces from values.yaml:123 (nodePort comment)
- Regenerated README.md with helm-docs to sync with values.yaml changes

yamllint now passes without errors (only warnings remain for long lines in docs).

- Kept MD024 (no-duplicate-heading) - fixed by renaming to "NetworkPolicy Troubleshooting"

README.md changes:
- Renamed "### Troubleshooting" to "### NetworkPolicy Troubleshooting" (line 406)
- Resolves MD024 duplicate heading error
