Hazelcast spring boot 应用程序不能作为 ec2 服务运行

Question

我使用this guide 中的代码创建了 Spring Boot 应用程序。 hazelcast.yaml 如下。

hazelcast:
  network:
    join:
      multicast:
        enabled: false
      aws:
        enabled: true
        host-header: ec2
    interfaces:
      enabled: true
      interfaces:
        - 10.9.*.*
  map:
    books:
      time-to-live-seconds: 60

但我得到错误

但是，当我尝试仅删除 host-header: ec2 的 Fargate 服务时，它起作用了。如何作为 ec2 服务运行？

Answer 1

该配置适用于 EC2 上的 ECS。

如果您使用的是 EC2 实例，请按如下方式进行配置

<hazelcast>
    <network>
         <join>
             <multicast enabled="false"/>
             <aws enabled="true">
                 <tag-key>my-ec2-instance-tag-key</tag-key>
                 <tag-value>my-ec2-instance-tag-value</tag-value>
             </aws>
        </join>
    </network>
</hazelcast>

参考以下链接 https://guides.hazelcast.org/ecs-embedded/

Answer 2

似乎由于某种原因该区域未从您的 EC2 实例解析。也许您禁用了元数据 API。我建议手动配置区域。

hazelcast:
  network:
    join:
      multicast:
        enabled: false
      aws:
        enabled: true
        region: <your-region>
        host-header: ec2
...
