带有Spring-boot的Hazelcast继续重新启动

Question

我正在部署一个弹簧启动应用程序，该应用程序正在将Hazelcast用于测试目的。在此部署（使用）中，只有一个实例。

Hazelcast的配置是这样：

hazelcast:
  network:
    join:
      multicast:
        enabled: false
      kubernetes:
        enabled: true
        service-dns: my-app-hs

它是在实际部署中应用的配置相同的配置，唯一的区别是，在实际部署中，至少有3个实例。

我现在看到的问题是Spring-Boot应用程序正在下降，并且新实例再次启动。

Answer 1

在我的情况下，问题是由于liveseprobe的配置问题而引起的。错误的端口是为LIVISE探针配置的。将端口固定为弹簧执行器之一，解决了问题。

livenessProbe {
    httpGet {
       path = "/actuator/health/liveness"
       this.port = IntOrString(managamentPort)
    }
    initialDelaySeconds = 60
    failureThreshold = 6
}
