我用本指南中的代码创建了spring-boot应用程序。榛子果。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
但是我收到错误

但当我尝试只删除host-header: ec2的fargate服务时，它成功了。如何作为ec2服务运行？
该配置适用于EC2上的ECS。
如果您使用的是EC2实例，则配置如下
<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>
请参阅以下链接https://guides.hazelcast.org/ecs-embedded/
由于某种原因，似乎没有从EC2实例中解析该区域。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
...
