我正在使用AWS Javascript SDK创建集群并注册ECS任务的容器实例。我为请求参数提供实例身份文档值而感到震惊。我正在尝试将运行中的EC2实例注册为容器实例。我通过执行以下命令curl
命令来获得实例身份文档。
curl http://169.254.169.254/latest/dynamic/instance-identity/document/
输出:
{
"accountId" : "01234567891",
"architecture" : "x86_64",
"availabilityZone" : "us-east-11",
"billingProducts" : null,
"devpayProductCodes" : null,
"marketplaceProductCodes" : null,
"imageId" : "ami-123456789012d",
"instanceId" : "i-12345678901",
"instanceType" : "t2.micro",
"kernelId" : null,
"pendingTime" : "2020-07-12T15:57:19Z",
"privateIp" : "172.31.33.40",
"ramdiskId" : null,
"region" : "us-east-1",
"version" : "2017-09-30"
}
我已将输出转换为字符串,但是NodeJS代码出现错误。

我们是否必须从EC2实例执行registerContainerInstances
API?
请指导!
答案 0 :(得分:1)
我已解决问题。利用EC2 SDK通过ECS AMI Image启动实例,并在用户数据中添加以下脚本。
#!/bin/bash
echo "ECS_CLUSTER=YOUR_CLUSTER_NAME" >> /etc/ecs/ecs.config
以上代码将注册到指定的ECS集群中。不需要使用registerContainerInstances
API。如果AWS从API参考中删除此API,那就太好了。
