feat: enable Kubernetes service discovery client - #142
Merged
Conversation
Add micronaut-kubernetes-discovery-client so the app discovers services in its own namespace via the Kubernetes API, populating the discovery client (previously the compositeDiscoveryClient health showed an empty services map). The module's beans require the k8s environment, so this stays inert in local/dev. In-cluster it needs RBAC to read services/endpoints (handled in the Helm chart) and the `k8s` environment active.

Why
In-cluster,
/healthshowedcompositeDiscoveryClientwith an emptyservices: {}— no discovery backend was configured. This adds Micronaut's Kubernetes discovery client so the app discovers services in its own namespace.What
micronaut-kubernetes-discovery-client(micronaut-kubernetes 7.1.1).The module's beans only activate in the Kubernetes environment, so it is inert for local/dev runs. In-cluster it additionally requires:
get/list/watchonservicesandendpoints(added in the Helm charthelm/micronaut).k8senvironment active (set via the deployment's profiles).See the companion Kubernetes-FLUX change for the RBAC + release wiring.
