Discovery Service Configuration (discovery-service)

The discovery-service runs the Eureka registry used by the platform services for service discovery.

Runtime and Service Metadata

These settings control the Eureka server process and how it identifies itself.

Property	Value / Default	Env Variable	Description
server.port	8761 dev	SERVER_PORT	Eureka server HTTP port.
server.shutdown	graceful	SERVER_SHUTDOWN	Shutdown mode. Allowed: graceful waits for in-flight requests to finish; immediate stops without waiting.
spring.profiles.active	dev	SPRING_PROFILES_ACTIVE	Active Spring profile. Common values: dev for local development or any custom profile with a matching application-<profile>.yml.
spring.application.name	discovery-service	SPRING_APPLICATION_NAME	Service name used by Spring.

Actuator and Health

Actuator is Spring Boot's operational endpoint layer. It exposes health and diagnostic endpoints used by operators, load balancers, and Kubernetes probes.

Property	Value / Default	Env Variable	Description
management.endpoints.web.exposure.include	*	MANAGEMENT_ENDPOINTS_WEB_EXPOSURE_INCLUDE	Actuator endpoints exposed over HTTP. Allowed examples: * exposes all; health,info exposes only health and info. Restrict this in production if actuator is reachable outside the private network.
management.info.env.enabled	true	MANAGEMENT_INFO_ENV_ENABLED	Environment-backed actuator info. Allowed: true includes configured info values; false hides environment-backed info.
management.endpoint.health.probes.enabled	true	MANAGEMENT_ENDPOINT_HEALTH_PROBES_ENABLED	Enables Kubernetes-style health probes. Allowed: true creates liveness/readiness health groups; false exposes only standard health behavior.
management.health.livenessstate.enabled	true	MANAGEMENT_HEALTH_LIVENESSSTATE_ENABLED	Liveness state indicator. Allowed: true exposes whether the process should be restarted; false disables this indicator.
management.health.readinessstate.enabled	true	MANAGEMENT_HEALTH_READINESSSTATE_ENABLED	Readiness state indicator. Allowed: true exposes whether the service is ready for traffic; false disables this indicator.

Eureka Server

The Eureka server stores service registrations. Other services register here and query it to find gateway, client, router, and aggregator instances.

Property	Value / Default	Env Variable	Description
eureka.server.enable-self-preservation	false	EUREKA_SERVER_ENABLE_SELF_PRESERVATION	Self-preservation mode. Allowed: true protects registrations during network partitions by reducing evictions; false evicts missed-heartbeat instances aggressively, which is simpler for local/dev environments.

Eureka Instance

These settings describe how the discovery server itself appears as a Eureka instance.

Property	Value / Default	Env Variable	Description
eureka.instance.preferIpAddress	true	EUREKA_INSTANCE_PREFER_IP_ADDRESS	Registration address type. Allowed: true registers the instance IP address; false registers hostname.
eureka.instance.leaseRenewalIntervalInSeconds	5	EUREKA_INSTANCE_LEASE_RENEWAL_INTERVAL_IN_SECONDS	Lease renewal interval.
eureka.instance.leaseExpirationDurationInSeconds	10	EUREKA_INSTANCE_LEASE_EXPIRATION_DURATION_IN_SECONDS	Lease expiration duration.
eureka.instance.instance-id	${spring.application.name}:${random.value}	EUREKA_INSTANCE_INSTANCE_ID	Registered Eureka instance ID.
eureka.instance.hostname	localhost dev	EUREKA_INSTANCE_HOSTNAME	Dev hostname for the Eureka server.

Eureka Client

These flags control whether the discovery server also behaves like a Eureka client. A single local registry normally leaves both disabled.

Property	Value / Default	Env Variable	Description
eureka.client.fetch-registry	false	EUREKA_CLIENT_FETCH_REGISTRY	Peer registry fetching. Allowed: true fetches registrations from another Eureka server; false keeps this node standalone.
eureka.client.register-with-eureka	false	EUREKA_CLIENT_REGISTER_WITH_EUREKA	Self-registration as a client. Allowed: true registers this server with another Eureka server; false does not self-register.
eureka.client.serviceUrl.defaultZone	http://localhost:8761/eureka/ dev	EUREKA_CLIENT_SERVICEURL_DEFAULTZONE	Dev Eureka default zone.

Logging

Property	Value / Default	Env Variable	Description
logging.config	classpath:log/logback-default.xml base, classpath:log/logback-dev.xml dev	LOGGING_CONFIG	Logback configuration. Dev overrides the base value.
