User is not authorized to perform: cloudformation:

问题:

I'm trying out Serverless to create AWS Lambdas and while creating a project using the command serverless project create I'm getting the following error.

AccessDenied: User: arn:aws:iam::XXXXXXXXX:user/XXXXXXXXX is not authorized to perform: cloudformation:CreateStack on resource: arn:aws:cloudformation:us-east-1:XXXXXXXXX:stack/XXXXXXXXX-development-r/*

I have created a user and granted the following permissions to the user.

1. AWSLambdaFullAccess
2. AmazonS3FullAccess
3. CloudFrontFullAccess
4. AWSCloudFormationReadOnlyAccess ( There was no AWSCloudFormationFullAccess to grant )

How can I proceed? What else permissions I have to grant?

回答1:

The closest one that you've mentioned is AWSCloudFormationReadOnlyAccess, but obviously that's for readonly and you need cloudformation:CreateStack. Add the following as a user policy.

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "Stmt1449904348000",
            "Effect": "Allow",
            "Action": [
                "cloudformation:CreateStack"
            ],
            "Resource": [
                "*"
            ]
        }
    ]
}

It's entirely possible you'll need more permissions- for instance, to launch an EC2 instance, to (re)configure security groups, etc.

What @tedder42 said, but I also had to add the following to my group policy before I could deploy to lambda from inside visual studio.

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "Stmt1449904348000",
            "Effect": "Allow",
            "Action": [
                "cloudformation:CreateStack",
                "cloudformation:CreateChangeSet",
                "cloudformation:ListStacks",
                "cloudformation:UpdateStack",
                "cloudformation:DescribeChangeSet",
                "cloudformation:ExecuteChangeSet"
            ],
            "Resource": [
                "*"
            ]
        }
    ]
}

In my recent experience the policy required was

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "Stmt1449904348000",
            "Effect": "Allow",
            "Action": [
                "cloudformation:CreateStack",
                "cloudformation:CreateChangeSet",
                "cloudformation:ListStacks",
                "cloudformation:UpdateStack",
                "cloudformation:DescribeStacks",
                "cloudformation:DescribeStackResource",
                "cloudformation:DescribeStackEvents",
                "cloudformation:ValidateTemplate",
                "cloudformation:DescribeChangeSet",
                "cloudformation:ExecuteChangeSet"
            ],
            "Resource": [
                "*"
            ]
        }
    ]
}

回答4:

if you have multiple AWS profiles, try to explicity

export AWS_ACCESS_KEY_ID=<value>
export AWS_SECRET_ACCESS_KEY=<value>

before trying

serverless deploy

I wasn't able to get the shorter versions shown above to work; what fixed things for me was extending @mancvso 's answer slightly to add "cloudformation:GetTemplateSummary":

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "Stmt1449904348000",
            "Effect": "Allow",
            "Action": [
                "cloudformation:CreateStack",
                "cloudformation:CreateChangeSet",
                "cloudformation:ListStacks",
                "cloudformation:UpdateStack",
                "cloudformation:DescribeStacks",
                "cloudformation:DescribeStackResource",
                "cloudformation:DescribeStackEvents",
                "cloudformation:ValidateTemplate",
                "cloudformation:DescribeChangeSet",
                "cloudformation:ExecuteChangeSet",
                "cloudformation:GetTemplateSummary"
            ],
            "Resource": [
                "*"
            ]
        }
    ]
}

These 2 helped me cross the line...

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "VisualEditor0",
            "Effect": "Allow",
            "Action": "apigateway:*",
            "Resource": "*"
        }
    ]
}

and

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "VisualEditor0",
            "Effect": "Allow",
            "Action": [
                "cloudformation:ListStacks",
                "cloudformation:DescribeStackEvents",
                "cloudformation:CreateStack",
                "cloudformation:UpdateStack",
                "cloudformation:DescribeStackResource",
                "cloudformation:CreateChangeSet",
                "cloudformation:DescribeChangeSet",
                "cloudformation:ExecuteChangeSet",
                "cloudformation:ValidateTemplate"
            ],
            "Resource": "*"
        }
    ]
}

回答7:

Create the following policy:

1. Click on Policy -> Create Policy
2. Under Select Service - Type EKS & Select 'EKS'
3. Under Actions: Select 'All EKS Actions'
4. Under Resources: Either select 'All resources' or Add ARN
5. Click on Review Policy
6. Type the name for the policy & create the policy.

Now, associate this policy to the user account. This should solve the issue & you should be able to create the stack.

With the recent updates in AWS, the following inline policy will also work.

{
   "Version": "2012-10-17",
   "Statement": [
       {
            "Sid": "VisualEditor0",
            "Effect": "Allow",
            "Action": [
                "cloudformation:DeleteStack"
            ],
            "Resource": "*"
        }
    ]
}

回答9:

There is a section in the docs on this (at least now).

With a gist showing the policies JSON they recommend.

Give "administrator" access to the user you created
