Question

我的节点应用程序已在eureka中注册，但是我在api网关中遇到以下异常。我正在使用eureka-js-client节点模块。

原因：java.lang.RuntimeException：java.net.UnknownHostException：utility-api：重试

我的eureka客户端配置为

                    const client = new Eureka({
                    //  application instance information 
                    instance: {
                        id: 'utility-api',    
                        instanceId: 'utility-api',
                        app: 'utility-api',
                        hostName: 'utility-api',
                        ipAddr: ip.address(),
                        port: {
                            '$': 8080,
                            '@enabled': true
                        },
                        vipAddress: 'utility-api',
                        statusPageUrl: 'http://'+ip.address()+':8080/info',
                        healthCheckUrl: 'http://'+ip.address()+':8080/info',

                        dataCenterInfo: {
                            '@class': 'com.netflix.appinfo.InstanceInfo$DefaultDataCenterInfo',
                            name: 'utility-api',

                        },

                    },
                    //eureka information
                    eureka: {
                        host: eurekaIp,
                        port: eurekaPort,
                        servicePath: '/eureka/apps',
                        // heartbeatInterval:1000,
                        // registerWithEureka:true
                    },
                });

我正在使用docker进行部署，而该应用使用了Express Server
