API7EE deployments cannot currently configure Service traffic distribution through Helm values. Add optional trafficDistribution values for the Dashboard, DP Manager, and Developer Portal Services so each can select PreferSameZone or another preference supported by the cluster.

The values default to an empty string, and the templates omit the field unless configured. Bump the chart from 3.10.12 to 3.10.13 and regenerate the README; application versions, image defaults, and dependencies are unchanged.

Example values:

dashboard_service:
  trafficDistribution: PreferSameZone
dp_manager_service:
  trafficDistribution: PreferSameZone
developer_portal_service:
  trafficDistribution: PreferSameZone

Summary by CodeRabbit

• New Features
  • Added an optional traffic distribution setting for the dashboard, developer portal, and DP manager services. When configured, the value is applied to the service; when empty, it is omitted. Supported values depend on Kubernetes version and feature gates.
• Chores
  • Updated the Helm chart version to 3.10.13.

Walkthrough

The chart adds an optional trafficDistribution value for the dashboard, developer portal, and DP manager Services. Configured values appear in the rendered Service specs. The chart version changes to 3.10.13.

Changes: Service traffic distribution

Layer / File(s)	Summary
Configure Service traffic distribution charts/api7/values.yaml, charts/api7/templates/*-service.yaml, charts/api7/README.md, charts/api7/Chart.yaml	Adds an empty default and optional template field for each of the three Services. The README documents the setting and its Kubernetes compatibility. The chart version changes to 3.10.13.

Merge Risk: Minimal · up to 6faa1

The optional settings preserve default Service behavior. No concrete merge-blocking issue remains; independent render checks would improve future regression protection.

Full details: Title check

Explanation

The title "feat(api7ee): expose Service trafficDistribution" matches the main change. The PR adds an optional trafficDistribution value to the API7EE Dashboard, DP Manager, and Developer Portal Services. The templates emit the field only when it is set. The chart version bump and README updates support this change.

Full details: Security Check

Explanation

No security issues found in the pull request. The changes only add an optional, quoted Kubernetes Service trafficDistribution field in three Helm templates (dashboard-service.yaml:14-16, developer-portal-service.yaml:15-17, dp-manager-service.yaml:14-16), with empty defaults in values.yaml:178-181, 208-211, and 248-251. No changed code logs or returns secrets, stores credentials, changes authorization, accesses resources, changes TLS settings, or resolves secret references. Categories 1-7: No issues found. Existing secret and password defaults are unchanged and are not introduced by this pull request.

Full details: E2e Test Quality Review

Explanation

Blocking: the PR adds no E2E test. The diff contains only chart metadata, values, templates, and README changes. CI installs charts/api7 with default values, but it does not set trafficDistribution, query the three Services, or verify behavior in a running Kubernetes cluster. The reported local render checks are not committed tests and do not cover the full install-to-Service flow. Dedicated scenario coverage is also absent for configured values and invalid values.

Resolution

Add a committed E2E test for charts/api7. Install the chart on a supported Kubernetes version with each Service set independently to PreferSameZone and verify with structured kubectl/API assertions that each Service has the expected spec.trafficDistribution. Run a default or empty-value install and verify the field is absent. Include an unsupported-value case and assert the intended Kubernetes rejection or documented handling. Keep each scenario isolated and check command errors.

charts/api7/templates/dp-manager-service.yaml: 1

14-15: Trivial · Maintainability & Code Quality · Low value

Add a render check that asserts each Service's trafficDistribution field.

CI renders charts/api7 only with empty trafficDistribution values. A template that reads the wrong Service key renders no field, so CI passes. A render check that sets one Service's value at a time, and asserts that the matching Service template emits the field, catches this wiring error. The check does not install the chart, so the Kubernetes API does not validate the value.
