![AWS IAM 策略问题:无法允许除 RunInstances 之外的所有实例](https://linux22.com/image/635950/AWS%20IAM%20%E7%AD%96%E7%95%A5%E9%97%AE%E9%A2%98%EF%BC%9A%E6%97%A0%E6%B3%95%E5%85%81%E8%AE%B8%E9%99%A4%20RunInstances%20%E4%B9%8B%E5%A4%96%E7%9A%84%E6%89%80%E6%9C%89%E5%AE%9E%E4%BE%8B.png)
我们正在努力创建一个允许所有 EC2 操作(RunInstances 除外)的 IAM 策略。这是为了防止 API 密钥泄露而启动未经授权的实例。我们尝试了带和不带 EC2 允许 * 的情况,因为我不清楚 NotAction 是否暗示了所有操作。
使用 NotAction 后,我无法配置 EBS 卷(如下)。我们是否需要将 EC2 允许 * 和 Notaction Runinstances 融合到同一个策略部分中?
EC2 所有权限:
“操作”:“ec2:", "效果": "允许", "资源": "“,
然后是第二条拒绝 RunInstances 的策略(来自先前关于类似主题的 IAM 政策答案
{ “语句”:[ { “NotAction”:[ “ec2:RunInstances*” ],“效果”:“拒绝”, “资源”:“*” } ] }

答案1
花费一个小时使用试用帐户和 IAM 模拟器来获得:
{
"Version": "2012-10-17",
"Statement": [
{
"NotAction": [
"ec2:RunInstances*"
],
"Effect": "Allow",
"Resource": "*"
},
{
"Effect": "Allow",
"Action": "elasticloadbalancing:*",
"Resource": "*"
},
{
"Effect": "Allow",
"Action": "cloudwatch:*",
"Resource": "*"
},
{
"Effect": "Allow",
"Action": "autoscaling:*",
"Resource": "*"
}
]
}
如果这对某人有用,你可以把你想要的任何操作放在 NotAction 下
