我要附加一个权限处的现有作用。 我是实现这种使用模板:
{
"AWSTemplateFormatVersion": "2010-09-09",
"Description": "AWS CloudFormation template to modify Role",
"Parameters": {
"MyRole": {
"Type": "String",
"Default": "MyRole",
"Description": "Role to be modified"
}
},
"Resources": {
"S3FullAccess": {
"Type": "AWS::IAM::ManagedPolicy",
"Properties": {
"PolicyDocument": {
"Version": "2012-10-17",
"Statement": [{
"Effect": "Allow",
"Action": [
"s3:*",
"s3-object-lambda:*"
],
"Resource": "*"
}]
},
"Roles": [
"MyRole"
]
}
}
}
}
这个模板将创建一个政策与s3FullAccess,并将其连接到MyRole. 但我不想创建一个新的政策,如果我想要使用的政策已经存与aws s3全的访问,我怎么可以这样做。
如果我使用这个模板:
{
"AWSTemplateFormatVersion": "2010-09-09",
"Description": "AWS CloudFormation template to modify Role",
"Resources": {
"IAMRole": {
"Type": "AWS::IAM::Role",
"Properties": {
"Path": "/",
"ManagedPolicyArns": [
"arn:aws:iam::aws:policy/ReadOnlyAccess"
],
"AssumeRolePolicyDocument": {
"Version": "2012-10-17",
"Statement": [{
"Action": "sts:AssumeRole",
"Effect": "Allow",
"Principal": {
"AWS": "*"
}
}]
},
"RoleName": "RoleName"
}
}
}
}
这将试图创建一个新的作用和附加ReadOnlyPolicy。 但是,如果我要附加政策对现有作用,如何参考这一作用的模板。
