我使用AWS IAM角色，让一个实例来访问使用临时API证书某些资源（访问密钥，密钥和安全令牌）。

当我测试使用这个Ruby脚本临时凭证，它运行没有任何问题：

 需要'rubygems的'
要求AWS-SDK
AWS.config（
    ：access_key_id =＆GT; 我的访问键GOES HERE，
    ：secret_access_key =＆GT; 我的秘密钥匙GOES HERE，
    ：session_token =＆GT; 我的TOKEN GOES HERE）
S3 = AWS :: S3.new（）
MYFILE = s3.buckets ['我的-配置']。对象[file.sh]
File.open方法（/ tmp目录/ file.sh，W）做| F |
    f.write（myfile.read）
结束
 

但是，使用命令行运行时，CFN-描述-栈我得到一个错误：

 出口AWS_CREDENTIAL_FILE = aws_credentials.cfg
CFN-描述，堆
CFN-描述-栈：拒绝：包含在请求安全令牌无效
 

和这里是我的aws_credentials.cfg：

  AWSAccessKeyId = MY快捷键
AWSSecretKey =我的秘密密钥
AWSToken =MY TOKEN ==
 

那么，我在这里丢失？谢谢！

我不认为CLI工具支持的临时凭证。如果他们这么做，你应该能够在通过您的AWSToken作为命令行参数。但据文档，它只支持传入访问密钥ID和密钥作为参数。   

-I，--access-key-id的值

指定值作为AWS访问标识使用。

-S，--secret键值

指定的值作为AWS密钥来使用。

I'm using AWS IAM roles that allows an instance to have access to certain resources using temporary API credentials (access key, secret key and security token).

When I test the temporary credentials using this ruby script, it runs without any problems :

require 'rubygems'
require 'aws-sdk'
AWS.config(
    :access_key_id     => "MY ACCESS KEY GOES HERE",
    :secret_access_key => "MY SECRET KEY GOES HERE",
    :session_token     => "MY TOKEN GOES HERE")
s3 = AWS::S3.new()
myfile = s3.buckets['My-Config'].objects["file.sh"]
File.open("/tmp/file.sh", "w") do |f|
    f.write(myfile.read)
end

But when using command line to run cfn-describe-stacks I get an error:

export AWS_CREDENTIAL_FILE=aws_credentials.cfg
cfn-describe-stacks
cfn-describe-stacks:  Refused: The security token included in the request is invalid

and here is my aws_credentials.cfg :

AWSAccessKeyId=MY ACCESS KEY
AWSSecretKey=My SECRET KEY
AWSToken="MY TOKEN=="

So what am i missing here ? Thank you!

I don't think that the CLI tools support temporary credentials. If they did, you should be able to pass your "AWSToken" in as a command line parameter. But according to the documentation, it only supports passing in the access key id and secret key as parameters.

-I, --access-key-id VALUE

Specify VALUE as the AWS Access ID to use.

-S, --secret-key VALUE

Specify VALUE as the AWS Secret Key to use.
