Hazelcast member discovery with PCF Registry Service and hazelcast-eureka-plugin

问题


Running several instances of application with embedded hazelcast on PCF. My goal is to chain hazelcast members into cluster. For purpose of member discovery I am using hazelcast-eureka plugin. I am able to achieve member discovery using simple Eureka Server app, passing eureka URL to hazelcast-eureka plugin, using this example. Now I want to use PCF Registry Service instead of Eureka Server app. For that purpose I am using EurekaOneDiscoveryStrategyFactory with EurekaClient autowired which is configured with PCF Registry Service properies.

Issue is - my hazelcast members do net get registered by PCF Registry Service, hence can not discover each other. Though I can see my application instances get registered by PCF Registry Service.

Instance config:

@Autowired
private EurekaClient eurekaClient;

@Bean
public HazelcastInstance hazelcastInstance() {
    return Hazelcast.newHazelcastInstance(cloudConfig());

}

@Bean
public Config cloudConfig(){
    Config config = new Config();
    config.getGroupConfig().setName( "hazelcast-test" );
    config.setProperty("hazelcast.discovery.enabled", Boolean.TRUE.toString());

    JoinConfig join = config.getNetworkConfig().getJoin();
    join.getMulticastConfig().setEnabled(false);

    EurekaOneDiscoveryStrategyFactory.setEurekaClient(eurekaClient);
    final EurekaOneDiscoveryStrategyFactory eurekaOneDiscoveryStrategyFactory = new EurekaOneDiscoveryStrategyFactory();

    DiscoveryStrategyConfig discoveryStrategyConfig =new DiscoveryStrategyConfig(eurekaOneDiscoveryStrategyFactory);
    discoveryStrategyConfig.addProperty("self-registration", true);
    discoveryStrategyConfig.addProperty("namespace", "hazelcast-test");
    discoveryStrategyConfig.addProperty("use-classpath-eureka-client-props", false);
    discoveryStrategyConfig.addProperty("shouldUseDns", false);
    discoveryStrategyConfig.addProperty("datacenter", "cloud");
    discoveryStrategyConfig.addProperty("name", "hazelcast-test");
    discoveryStrategyConfig.addProperty("use-metadata-for-host-and-port", false);
    discoveryStrategyConfig.addProperty("skip-eureka-registration-verification", false);


    DiscoveryConfig discoveryConfig = new DiscoveryConfig();
    discoveryConfig.addDiscoveryStrategyConfig( discoveryStrategyConfig );
    join.setDiscoveryConfig( discoveryConfig );
    return config;
}
