Deploy eureka and promethus into Docker swarm, prometheus error msg:

dial tcp: lookup swarm-eureka on 127.0.0.11:53: no such host

I can only guess. Looks like you got the wrong dns name.

@GetMapping(value = "/v1/catalog/service/{appName}", produces = MediaType.APPLICATION_JSON_VALUE)
public Single<ResponseEntity<List<Service>>> getService(@PathVariable("appName") String appName,
    @QueryParam(QUERY_PARAM_WAIT) String wait,
    @QueryParam(QUERY_PARAM_INDEX) Long index) {
    Assert.isTrue(appName != null, "service name can not be null");
    Single<ChangeItem<List<InstanceInfo>>> service = registrationService.getService(appName, getWaitMillis(wait), index);

    return registrationService.getService(appName, getWaitMillis(wait), index)
        .map(item -> {
            List<Service> services = item.getItem().stream().map(instanceInfoMapper::map).collect(toList());
            // docker swarm，use instance id(dns)
            if (dockerSwarm) {
                services.forEach(service1 -> {
                    **String serviceId = service1.getServiceID();
                    String[] split = serviceId.split(":");
                    service1.setAddress(split[0]);
                    service1.setServiceAddress(serviceId);**
                });
            }
            return createResponseEntity(services, item.getChangeIndex());
        });
}

But,I got another error: Eureka: w.s.m.s.DefaultHandlerExceptionResolver Resolved [org.springframework.web.context.request.async.AsyncRequestTimeoutException]

Have a look at the required timeout configuration in the Readme.
