AWS Identity and Access Management (IAM) 是一种 Web 服务,可以帮助您安全地控制对 AWS 资源的访问。您可以使用 IAM 控制对哪个用户进行身份验证 (登录) 和授权 (具有权限) 以使用资源。

AWS上有IAM的概念,IAM角色可以更加精准的控制权限,方便扩展。
针对 EC2 上面的应用程序,不要分配 User Credentials,使用 IAM Role Attachment。
可以访问 EC2 的 meatdata 查看赋予的 Role 权限
curl http://169.254.169.254/latest/meta-data/iam/security-credentials/
针对在自己电脑上面开发测试的用户,用户需要 S3 的访问权限,不给用户分配权限,这样可以避免 AK/SK 丢失造成的损失,我们可以给 User 分配一个 Cross accunt role,让用户使用接口 assume-role 获取临时的 AK/SK,然后去访问AWS 资源。
不给用户分配任何权限。
最后得到用户的 AK/SK
Access key ID :AKIA5NAGHF6N2WFTQZP6
Secret access key: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
给角色增加权限。
生成的 Role ARN:arn:aws:iam::921283538843:role/alice-sts
把生成的 Role 的 trust relationships policy 修改为如下,试 alice 这个用户可以 assumerole 这个角色,
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Principal": {
"AWS": "arn:aws:iam::921283538843:user/alice"
},
"Action": "sts:AssumeRole",
"Condition": {}
}
]
}
直接使用 AK/SK,查看用户是否有相应的权限。
使用 aws configure
配置。
wangzan:~/.aws $ aws configure --profile alice
AWS Access Key ID [****************H6YU]: AKIA5NAGHF6N2WFTQZP6
AWS Secret Access Key [****************bVA/]: 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
Default region name [us-east-1]:
Default output format [json]:
wangzan:~/.aws $ aws sts get-caller-identity --profile alice
{
"Account": "921283538843",
"UserId": "AIDA5NAGHF6NZASTSA7Y6",
"Arn": "arn:aws:iam::921283538843:user/alice"
}
wangzan:~/.aws $ aws s3 ls --profile alice
An error occurred (AccessDenied) when calling the ListBuckets operation: Access Denied
直接使用是获取不到权限的,那我们使用 assume-role。
wangzan:~ $ aws sts assume-role --role-arn arn:aws:iam::921283538843:role/alice-sts --role-session-name alice1233 --profile alice
{
"AssumedRoleUser": {
"AssumedRoleId": "AROA5NAGHF6N7DOEADJSU:alice1233",
"Arn": "arn:aws:sts::921283538843:assumed-role/alice-sts/alice1233"
},
"Credentials": {
"SecretAccessKey": "bmP9j6fuZ03MgrQCzrix6YLRcHzLojrThII6I5k7",
"SessionToken": "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",
"Expiration": "2019-12-31T09:06:12Z",
"AccessKeyId": "ASIA5NAGHF6NZZ5HBX7R"
}
}
然后去编辑 ~/.aws/credentials,把生成的Credentials放到里面,如下:
[alice-sts]
aws_access_key_id = ASIA5NAGHF6NZZ5HBX7R
aws_secret_access_key = bmP9j6fuZ03MgrQCzrix6YLRcHzLojrThII6I5k7
aws_session_token = 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
然后再去请求 S3。
wangzan:~/.aws $ aws sts get-caller-identity --profile alice-sts
{
"Account": "921283538843",
"UserId": "AROA5NAGHF6N7DOEADJSU:alice1233",
"Arn": "arn:aws:sts::921283538843:assumed-role/alice-sts/alice1233"
}
修改 ~/.aws/credentials,增加如下字段,
[alice-auto]
role_arn = arn:aws:iam::921283538843:role/alice-sts
source_profile = alice
可以看下目前的 Role。
wangzan:~ $ aws sts get-caller-identity --profile alice-auto
{
"Account": "921283538843",
"UserId": "AROA5NAGHF6N7DOEADJSU:botocore-session-1577780458",
"Arn": "arn:aws:sts::921283538843:assumed-role/alice-sts/botocore-session-1577780458"
}
