发现/注册只有在K8s吊舱已经注册时才起作用。

Question

感谢Spring开机管理！

我在Spring Cloud Kubernetes中使用它，我们的k8s豆荚只有在服务豆荚启动后启动Spring Boot Admin时才会被发现。

版本：

    springBootAdminVersion = '2.0.1'
    springCloudVersion = 'Finchley.RELEASE'
    springCloudK8s = '0.3.0.RELEASE'

不确定这是否是解决问题的最佳方法，但似乎有效：

class TimedInstanceDiscoveryListener extends InstanceDiscoveryListener {

    private static final Logger log = LoggerFactory.getLogger(TimedInstanceDiscoveryListener.class);

    public TimedInstanceDiscoveryListener(DiscoveryClient discoveryClient, InstanceRegistry registry, InstanceRepository repository) {
        super(discoveryClient, registry, repository);
        log.info("Starting custom TimedInstanceDiscoveryListener");
    }

    @Scheduled(fixedRate = 5000)
    public void periodicDiscovery() {
        log.info("Discovering new pod / services");
        super.discover();
    }
}

@Bean
@ConfigurationProperties(prefix = "spring.boot.admin.discovery")
public InstanceDiscoveryListener instanceDiscoveryListener(ServiceInstanceConverter serviceInstanceConverter,
                                                           DiscoveryClient discoveryClient,
                                                           InstanceRegistry registry,
                                                           InstanceRepository repository) {

    InstanceDiscoveryListener listener = new TimedInstanceDiscoveryListener(discoveryClient, registry, repository);
    listener.setConverter(serviceInstanceConverter);
    return listener;
}
