command: node index.js directory: ... environment:   DNS_HOST=127.0.0.1   DNS_PORT=53053   DNS_NAMESPACE=micro   DNS_SUFFIX=svc.cluster.local   AUDITSERVICE_SERVICE_HOST=127.0.0.1   AUDITSERVICE_SERVICE_PORT=8081   AUDITSERVICE_PORT=tcp://127.0.0.1:8081   AUDITSERVICE_PORT_8081_TCP=tcp://127.0.0.1:8081 AUDITSERVICE_PORT_8081_TCP_PROTO=tcp ...
