Question

上下文：AWS，S3， Lambda ，批量。

我有一个在S3 Bucket上传文件时触发的lambda。我希望lambda提交批处理作业。

（编辑：在S3和Lambda之间一切正常。问题出在Lambda和Batch之间。）

问：为了能够提交批处理作业，我必须为 lambda 提供什么角色？

我的lambda获得AccessDeniedException并且在以下情况下无法提交作业：

const params = {
  jobDefinition: BATCH_JOB_DEFINITION,
  jobName: BATCH_JOB_NAME,
  jobQueue: BATCH_JOB_QUEUE,
};

Batch.submitJob(params).promise() .then .......

Answer 1

这似乎是我正在寻找的角色：batch:SubmitJob。使用此角色，lambda能够提交作业。

iamRoleStatements:
  - Effect: Allow
    Action:
      - batch:SubmitJob
    Resource: "arn:aws:batch:*:*:*"

Answer 2

您可以创建类似AWS Batch Managed Policy，

的政策

以下政策允许管理员访问权限，您可以根据需要进行修改：

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "batch:*",
                "cloudwatch:GetMetricStatistics",
                "ec2:DescribeSubnets",
                "ec2:DescribeSecurityGroups",
                "ec2:DescribeKeyPairs",
                "ecs:DescribeClusters",
                "ecs:Describe*",
                "ecs:List*",
                "logs:Describe*",
                "logs:Get*",
                "logs:TestMetricFilter",
                "logs:FilterLogEvents",
                "iam:ListInstanceProfiles",
                "iam:ListRoles"
            ],
            "Resource": "*"
        },
        {
            "Effect": "Allow",
            "Action": ["iam:PassRole"],
            "Resource": [
                "arn:aws:iam::*:role/AWSBatchServiceRole",
                "arn:aws:iam::*:role/ecsInstanceRole",
                "arn:aws:iam::*:role/iaws-ec2-spot-fleet-role",
                "arn:aws:iam::*:role/aws-ec2-spot-fleet-role",
                "arn:aws:iam::*:role/AWSBatchJobRole*"
            ]
        }
    ]
}

将策略附加到lambda并再次尝试，请参阅AWS Documentation
