Summary by CodeRabbit

  • New Features

    • Added support for configuring additional Kubernetes Deployment annotations across CDN, Control Plane, GraphQL Metrics, OpenTelemetry Collector, Router, and Studio Helm charts.
    • Annotation settings default to an empty map and are applied to generated Deployments.
  • Documentation

    • Updated Helm chart value references with descriptions and defaults for the new configuration option.
    • Expanded documentation for previously undocumented chart settings.

Review Change Stack

Walkthrough

The six Helm charts now define additionalDeploymentAnnotations values and render them in Deployment metadata. Chart README values tables document the new setting and add descriptions for existing settings.

Changes

Deployment annotation configuration

Layer / File(s) Summary
Annotation configuration and rendering
helm/cosmo/charts/{cdn,controlplane,graphqlmetrics,otelcollector,router,studio}/values.yaml, helm/cosmo/charts/{cdn,controlplane,graphqlmetrics,otelcollector,router,studio}/templates/deployment.yaml
Each chart adds an empty additionalDeploymentAnnotations map and renders its contents in Deployment metadata. The router whitespace and Studio image comment changes have no semantic effect.

Values documentation

Layer / File(s) Summary
Values documentation
helm/cosmo/charts/{cdn,controlplane,graphqlmetrics,otelcollector,router,studio}/README.md
The chart README tables document additionalDeploymentAnnotations. Existing settings receive expanded descriptions in the CDN, controlplane, and graphqlmetrics tables.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟠 High · up to c45a7

The new deployment-label support currently prevents the CDN and control-plane Helm Deployments from rendering, so installations or upgrades can fail until the missing helpers are defined.

Define the annotation helpers before using them. cdn.additionalDeploymentAnnotations and controlplane.additionalDeploymentAnnotations are undefined, so Helm cannot render either Deployment. Add both helpers and reject reserved kapp.k14s.io keys before emitting user annotations.
