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;
}
