Configured API7 Gateway to use Kubernetes Service Discovery instead of
static upstream nodes. This enables dynamic discovery of backend Pods
through the Kubernetes API.
Benefits:
- Automatic scaling: New Pods are automatically added to upstream pool
- Health checks: Only healthy Pods receive traffic
- Zero downtime: Automatic updates during deployments and rollouts
- No manual upstream configuration needed
Changes:
- Updated configmap-adc.yaml to use discovery_type: kubernetes
- Service discovery queries Kubernetes API for Pod endpoints
- Falls back to static nodes if serviceDiscovery.enabled is false
- Added documentation in values.yaml explaining the feature
The RBAC permissions (services, endpoints watch) were already configured
in rbac-adc.yaml, so no additional permissions are needed.
