我们如何在不使用秘密访问密钥的情况下使用带有 IAM 角色的 boto3 连接到 Amazon CloudWatch

Question

client = boto3.client('logs','us-west-2')
response = client.attach_role_policy(
    RoleName='',
    PolicyArn=''
)

The above code is giving me error:

AttributeError: 'CloudWatchLogs' object has no attribute 'attach_role_policy'

Answer 1

The client you have defined is a CloudWatch Logs client, which has no method called attach_role_policy - this is a method on the IAM client, so for example:

logs_client = boto3.client('logs','us-west-2')
iam_client = boto3.client('iam', 'us-west-2')

and then you can use

iam_client.attach_role_policy(...)
