Enable Poimen orchestrator and worker pods to reach the LLM API gateway in the api namespace. The api-gateway NetworkPolicy was only allowing traffic from: - ingress-nginx (external ingress) - monitoring (Prometheus scraping) Added new ingress rule to allow: - poimen namespace (orchestrator-job and worker pods) - Port 8080 (api-gateway service port) This fixes the DNS resolution error where orchestrator pods couldn't reach http://api-gateway.api:8080/health from within the cluster. Managed via ArgoCD in homelab/k8s/argocd/apps/55-api-gateway.yaml which syncs from this repo's k8s/ directory.
