User is not authorized to perform: cloudformation:CreateStack

Question

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.

Answer 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.
