如何创建实例类型为t2.micro的ec2 cloudformation策略 [英] how to create a policy of ec2 cloudformation with instancetype t2.micro

问题描述

我正在尝试创建一个策略，使某些用户可以在特定区域中使用amid:ami-0fc61db8544a617ed特定实例和instancetype:t2.micro放置实例，并使用8gb这样的特定存储空间我有这个模板

I am trying to create a policy where some user can lauch instance with amid:ami-0fc61db8544a617ed specific and instancetype:t2.micro in a specific region with specific storage like 8gb I have this template

AWSTemplateFormatVersion: 2010-09-09
    Description: ---
      Policita para usuarios test
    Parameters:
      GroupTest1Parameter:
        Type: String
        Default: GroupTest1
        Description: Este es el valor de entrada GroupTest1Parameter
    Resources:
      PolictyTest1:
        Type: AWS::IAM::Policy
        Properties:
          PolicyName: PolictyTest1
          Groups:
            - Fn::ImportValue: !Sub "${GroupTest1Parameter}-VPCID"
          PolicyDocument:
            Version: '2012-10-17'
            Statement:
              - Effect: Allow
                Action:
                  - 'ec2:RunInstances'
                  - 'cloudformation:Describe*'
                  - 'cloudformation:List*'
                  - 'cloudformation:Get*'
                Resource: 'arn:aws:ec2:*:*:instance/*'
                # Condition:
                #   StringEquals: 
                #     ec2:ImageType: ami-0fc61db8544a617ed
    Outputs:
      PolictyTest1:
        Description: politica que deniega
        Value: !Ref PolictyTest1
        Export:
          Name: !Sub "${AWS::StackName}-VPCID"

但是它不起作用.该模板可以很好地创建模板，但是当我尝试使用与此策略相关的用户测试来测试策略时，他不能对ec2实例进行处理我在读 https://docs.aws.amazon.com/IAM/latest/UserGuide/list_amazonec2.html#amazonec2-actions-as-permissions

But it does not work. The template creates fine, but when I am trying to test te policy by using a user test related to this policy, he can not lauch instances of ec2 I am reading https://docs.aws.amazon.com/IAM/latest/UserGuide/list_amazonec2.html#amazonec2-actions-as-permissions

推荐答案

要测试您的方案，我执行了以下操作:

To test your scenario, I did the following:

• 创建了一个IAM用户
• 将此串联策略分配给用户:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "ec2:RunInstances",
            "Resource": [
                "arn:aws:ec2:*:ACCOUNT:network-interface/*",
                "arn:aws:ec2:*:ACCOUNT:volume/*",
                "arn:aws:ec2:*:ACCOUNT:key-pair/*",
                "arn:aws:ec2:*:ACCOUNT:security-group/*",
                "arn:aws:ec2:*:ACCOUNT:subnet/*",
                "arn:aws:ec2:*::image/ami-*"
            ]
        },
        {
            "Effect": "Allow",
            "Action": "ec2:RunInstances",
            "Resource": [
                "arn:aws:ec2:*:ACCOUNT:instance/*"
            ],
            "Condition": {
                "StringEquals": {
                    "ec2:InstanceType": "t2.micro"
                }
            }
        }
    ]
}

(其中将 ACCOUNT 设置为我的AWS账户ID.)

(Where ACCOUNT was set to my AWS Account ID.)

然后，我能够使用以下命令成功启动 t2.micro 实例:

I was then able to successfully launch a t2.micro instance using:

aws ec2 run-instances --image-id ami-xxx --security-group-id sg-xxx --instance-type t2.micro

我尝试将其更改为 t2.nano ，并收到了 UnauthorizedOperation 错误.

I tried changing it to t2.nano and received a UnauthorizedOperation error.

请注意，上面的 run-instances 命令非常少.它故意没有尝试指定诸如以下内容:

Please note that the above run-instances command was quite minimal. It intentionally did not attempt to specify things like:

• IAM角色
• 标签
• 密钥对

这些项目需要向用户授予其他权限.因此，在测试策略时，请使用最少的一组要求(与上述类似)来测试策略.

These items require granting of additional permissions to the user. Therefore, when testing your policy, use a minimal set of requirements (similar to the above) to test the policy.
