我正在尝试通过cloudformation创建我的认知资源。下面的模板可以正常工作；
AWSTemplateFormatVersion: 2010-09-09
Resources:
CognitoAuthRole:
Type: 'AWS::IAM::Role'
Properties:
AssumeRolePolicyDocument:

CognitoIdentityPool:

Type: 'AWS::Cognito::IdentityPoolRoleAttachment'
Properties:
IdentityPoolId:
Ref: CognitoIdentityPool
Roles:
authenticated:
'Fn::GetAtt':
- CognitoAuthRole
- Arn
但是，当我将RoleMappings属性添加到CognitoIdentityPoolRoles资源时，Cloudformation返回错误并且无法创建堆栈。修改后的资源如下；
CognitoIdentityPoolRoles:
Type: 'AWS::Cognito::IdentityPoolRoleAttachment'
Properties:
IdentityPoolId:
Ref: CognitoIdentityPool
Roles:
authenticated:
'Fn::GetAtt':
- CognitoAuthRole
- Arn
RoleMappings:
AmbiguousRoleResolution: Deny
Type: Rules
RulesConfiguration:
Rules:
- Claim: 'custom:role'
MatchType: Equals
Value: viewer
RoleARN:
'Fn::GetAtt':
- CognitoAuthRole
- Arn
- Claim: 'custom:role'
MatchType: Equals
Value: editor
RoleARN:
'Fn::GetAtt':
- CognitoAuthRole
- Arn
如您所见，RoleMappings的类型为“规则”。您可以尝试使用Token参数，并且结果不会改变。
CognitoIdentityPoolRoles:
Type: 'AWS::Cognito::IdentityPoolRoleAttachment'
Properties:
IdentityPoolId:
Ref: CognitoIdentityPool
Roles:
authenticated:
'Fn::GetAtt':
- CognitoAuthRole
- Arn
RoleMappings:
AmbiguousRoleResolution: Deny
Type: Token
不幸的是，错误消息没有提供任何线索，我无法取得任何进展，并停留在此阶段。
Status Type Logical ID Status Reason
CREATE_FAILED AWS::Cognito::IdentityPoolRoleAttachment CognitoIdentityPoolRoles Internal Failure
如何使带有RoleMappings的IdentityPoolRoleAttachment工作？
答案 0 :(得分：1)
我遇到了同样的问题，不幸的是，我看到CloudFormation还不支持RoleMappings，所以我们永远都会遇到这种“内部故障”。 但是，您可以采取一些解决方法来解决问题。在我的情况下，我使用了boto3 library来调用 Lambda函数中的IdentityPool更新，并且使用了 Severless Framework ，但是相同的目的可能是使用SAM或其他CloudFormation堆栈框架。 因此，我使用2个单独的堆栈完成了这些步骤：

最后，lambda函数的代码通过 boto3 调用执行更新，为此，我使用了 python3.6 ，但是可以使用 Node （must see the boto3 docs for Node）
import boto3
import os
def handler(event, context):
setup_cognito()
return event
def setup_cognito():
define_cognito_attributes()
create_cognito_identity_roles()
def create_cognito_identity_roles():
user_pool_region = os.environ['USER_POOL_REGION']
user_pool_id = os.environ['USER_POOL_ID']
user_pool_client_id = os.environ['USER_POOL_CLIENT_ID']
identity_pool_id = os.environ['IDENTITY_POOL_ID']
administrador_role = os.environ['ADMINISTRADOR_ROLE_ARN']
gerenciador_role = os.environ['GERENCIADOR_ROLE_ARN']
client_identity = boto3.client('cognito-identity')
client_idp = boto3.client('cognito-idp')
response = client_identity.get_identity_pool_roles(IdentityPoolId=identity_pool_id)
identity_provider = "cognito-idp.{}.amazonaws.com/{}:{}".format(user_pool_region, user_pool_id, user_pool_client_id)
options = {
'IdentityPoolId': response['IdentityPoolId'],
'Roles': response['Roles'],
'RoleMappings': {
identity_provider: {
'Type': 'Rules',
'AmbiguousRoleResolution': 'AuthenticatedRole',
'RulesConfiguration': {
'Rules': [
{
'Claim': 'custom:permission',
'MatchType': 'Equals',
'Value': 'ADMNISTRADOR',
'RoleARN': administrador_role
},
{
'Claim': 'custom:permission',
'MatchType': 'Equals',
'Value': 'GERENCIADOR',
'RoleARN': gerenciador_role
}
]
}
}
}
}
response = client_identity.set_identity_pool_roles(IdentityPoolId=options['IdentityPoolId'], Roles=options['Roles'], RoleMappings=options['RoleMappings'])
def define_cognito_attributes():
user_pool_id = os.environ['USER_POOL_ID']
user_pool_client_id = os.environ['USER_POOL_CLIENT_ID']
client = boto3.client('cognito-idp')
response = client.update_user_pool_client(
UserPoolId=user_pool_id,
ClientId=user_pool_client_id,
WriteAttributes=[
'custom:permission',
'phone_number',
'email',
'name',
'family_name',
'gender'
]
)
创建后，可以通过 CLI 或 WEB'测试'按钮调用lambda函数，然后将您希望的角色映射分配给您IdentityPool。 / p>
希望它可以为您提供帮助！ （是）
