amazon-web-services – 无法在InstanceProfileCredentialsProvider上加载EC2实例的凭据

2019年7月22日 366次阅读

我已将EC2角色附加到实例,我的EC2实例,并且我正在运行AWS JAVA SDK.当我尝试以这种方式加载凭据时：

InstanceProfileCredentialsProvider instanceCred = new InstanceProfileCredentialsProvider();

我收到以下错误：

Exception in thread "main" com.amazonaws.AmazonClientException: Unable to load credentials.
    at com.amazonaws.auth.InstanceProfileCredentialsProvider.loadCredentials(InstanceProfileCredentialsProvider.java:195)
    at com.amazonaws.auth.InstanceProfileCredentialsProvider.getCredentials(InstanceProfileCredentialsProvider.java:124)

可以建议我可能会缺少什么吗？

最佳答案 通过运行我的EC2实例中的代码并增强我的代码,我能够绕过它,这里是代码：

 String arn = "arn:aws:iam::"+accountnumber+":role/My-CrossAccount-CustomRole-ReadOnly";

InstanceProfileCredentialsProvider instanceCred = new InstanceProfileCredentialsProvider();

stscred = new STSAssumeRoleSessionCredentialsProvider(instanceCred.getCredentials(),arn,"123",clientConfiguration);

确保角色操作中有“sts：AssumeRole”.
