feat(aisix-cp): support extra UI volumes for private CA trust

[juzhiyuan]

The dashboard cannot mount a private PostgreSQL CA through chart values, so database-backed authentication can fail with SELF_SIGNED_CERT_IN_CHAIN even when the dashboard page loads.

Add empty-by-default ui.extraVolumes and ui.extraVolumeMounts, appended alongside the existing Next.js cache. Operators can mount a ConfigMap or Secret and configure NODE_EXTRA_CA_CERTS through ui.extraEnvVars. The chart README and its helm-docs template explain same-namespace provisioning, read-only mounts, and the dashboard rollout required after CA rotation.

Publish chart 1.2.1 against the current 1.2.0 application images. This is a chart-only patch; TLS verification and existing defaults are preserved. The same extension points and regression coverage are being carried back to the control-plane chart source so a later release sync retains them.

Fixes #378

📝 Walkthrough

Walkthrough

The aisix-cp chart now supports configurable UI volumes and volume mounts. Documentation describes mounting a private PostgreSQL CA and configuring NODE_EXTRA_CA_CERTS. The chart version increases to 1.1.1.

Changes

UI extra volume support

Layer / File(s)	Summary
Chart values and deployment rendering charts/aisix-cp/values.yaml, charts/aisix-cp/templates/ui-deployment.yaml	Adds empty ui.extraVolumes and ui.extraVolumeMounts defaults. Renders supplied volumes and mounts alongside the existing next-cache entries.
CA configuration documentation and chart release metadata charts/aisix-cp/README.md, charts/aisix-cp/README.md.gotmpl, charts/aisix-cp/Chart.yaml	Documents ConfigMap and Secret CA volumes, NODE_EXTRA_CA_CERTS, same-namespace provisioning, and rollout requirements. Updates the chart version and badge to 1.1.1.

Merge Risk: 🟡 Moderate · up to 2cd92

This chart release advertises version 1.1.1 while retaining appVersion 1.1.0, which can cause inconsistent paired-chart metadata and default UI image selection. Align the release version, appVersion, and image-tag choice before merging.

Full details: E2e Test Quality Review

Explanation

Blocking issue: the PR adds no E2E test for the requested authentication flow. The exact PR diff contains only chart, template, values, and documentation changes. The repository has no chart-specific test files, and CI runs ct lint for aisix-cp but does not run ct install or an application-level test for it. The PR description also states that no live deployment or end-to-end authentication test was performed. Static Helm rendering checks do not cover dashboard → PostgreSQL → signup/login behavior.

Resolution

Add an executable E2E test using real deployed services. Install the chart with a private-CA PostgreSQL instance, provision the CA through both ConfigMap and Secret scenarios as applicable, configure NODE_EXTRA_CA_CERTS, wait for the UI and database to become ready, and assert that signup and sign-in succeed without SELF_SIGNED_CERT_IN_CHAIN. Include default-value coverage to confirm the existing next-cache mount remains, and test invalid or missing CA configuration with clear failure assertions. Run the test in CI or document an equivalent required integration job.
