我有一个测试模板,它使用 cfn-init
从 S3 存储桶下载单个非公开文件。和一个AWS::CloudFormation::Authentication
和AWS::CloudFormation::Init
部分。
这在 Amazon AMI 上成功运行,但在 Ubuntu AMI 上失败并出现以下错误:
WARNING [2017-10-29 12:01:03,541] Unable to retrieve remote metadata : No credentials! WARNING [2017-10-29 12:01:03,541] Unable to open local metadata : /var/cache/heat-cfntools/last_metadata WARNING [2017-10-29 12:01:03,542] Unable to open local metadata : /var/lib/heat-cfntools/cfn-init-data ERROR [2017-10-29 12:01:03,542] Unable to read any valid metadata!

I found a similar question on Launchpad, but it has no answer.
Edit: This is the output from curl 169.254.169.254/latest/meta-data/iam/info/
:
{
"Code" : "InstanceProfileNotFound",
"Message" : "Instance Profile with Id AIPAJWC744OTCCS55JMTW cannot be found. Please see documentation at http://docs.amazonwebservices.com/IAM/latest/UserGuide/RolesTroubleshooting.html.",

最佳答案
您正在指定一个名为“s3access”的角色,但您并未声明它。如果它尚不存在,您需要创建它。
将其添加到资源中,并更改 Bucket_Name(2 个条目)和 Path_Name(1 个条目)以匹配您的配置:
"s3access": {
"Type": "AWS::IAM::Role",
"Properties": {
"AssumeRolePolicyDocument": {
"Version": "2012-10-17",
"Statement": [{
"Effect": "Allow",
"Principal": {
"Service": ["ec2.amazonaws.com"]
},
"Action": ["sts:AssumeRole"]
}]
},
"Path": "/",
"Policies": [{
"PolicyName": "S3_Read",
"PolicyDocument": {
"Version": "2012-10-17",
"Statement": [{
"Effect": "Allow",
"Action": "s3:GetObject",
"Resource": [{
"Fn::Join": ["", ["arn:aws:s3:::", "Bucket_Name", "/Path_Name/*"]]
}, ]
},
{
"Effect": "Allow",
"Action": "s3:ListBucket",
"Resource": [{
"Fn::Join": ["", ["arn:aws:s3:::", "Bucket_Name"]]
}]
}
]
}
}]
}
}
