如何使用元数据端点或java sdk获取FARGATE ECS任务的公共IP?

我用DescribeNetworkInterfacesRequest解决了我的问题。我使用获取容器的私有IP 卷曲 http://169.254.170.2/v2/metadata/ 然后运行此代码。

    AmazonEC2 ec2AsyncClient= AmazonEC2ClientBuilder.standard().withCredentials(new 
    AWSStaticCredentialsProvider(credentials)).build();

    DescribeNetworkInterfacesRequest request = new DescribeNetworkInterfacesRequest();
    request.withFilters(new Filter().withName("private-ip-address").withValues("my-container-private-Ip"));
    DescribeNetworkInterfacesResult result = ec2AsyncClient.describeNetworkInterfaces(request);
    String publicIP = result.getNetworkInterfaces().get(0).getAssociation().getPublicDnsName();
