【问题描述】：

在 AWS 上对会话管理器进行健康检查时遇到以下错误：

amazon-ssm-agent[17614]: 2020-05-19 12:57:35 ERROR [MessagingDeliveryService] [Association] Unable to load instance associations, unable to retrieve associations unable to retrieve associations AccessDeniedException: User: arn:aws:sts::395456465418:assumed-role/SessionManagerInstanceProfile/i-02c8c2ae1dce2ce84 is not authorized to perform: ssm:ListAssociations on resource: arn:aws:ssm:ap-southeast-1:395456465418:*

相信这是由于为实例 IAM 策略授予的权限不足造成的。但是为了解决这个错误，我应该授予什么额外的访问权限？

以下是从 AWS 文档复制的当前内联策略。

{
"Version": "2012-10-17",
"Statement": [
    {
        "Effect": "Allow",
        "Action": [
            "ssmmessages:CreateControlChannel",
            "ssmmessages:CreateDataChannel",
            "ssmmessages:OpenControlChannel",
            "ssmmessages:OpenDataChannel",
            "ssm:UpdateInstanceInformation"
        ],
        "Resource": "*"
    },
    {
        "Effect": "Allow",
        "Action": [
            "logs:CreateLogStream",
            "logs:PutLogEvents",
            "logs:DescribeLogGroups",
            "logs:DescribeLogStreams"
        ],
        "Resource": "*"
    },
    {
        "Effect": "Allow",
        "Action": [
            "s3:PutObject"
        ],
        "Resource": "arn:aws:s3:::ec2-sessionmanager-logs"
    },
    {
        "Effect": "Allow",
        "Action": [
            "s3:GetEncryptionConfiguration"
        ],
        "Resource": "*"
    },
    {
        "Effect": "Allow",
        "Action": "kms:GenerateDataKey",
        "Resource": "*"
    }
]

}

【解决方案1】：

错误信息提示：

无权执行：ssm:ListAssociations

动作：

授予列出指定 SSM 文档或托管实例的关联的权限

因此，策略应包含：ssm:ListAssociations。目前，在您在问题中发布的政策中，不允许此类操作。
