Context: AWS, S3, Lambda, Batch.

I have a lambda that is triggered when a file is uploaded in a S3 Bucket. I want that the lambda submit a Batch job.

(edit: Between S3 and Lambda everything works fine. The problem is between Lambda and Batch.)

Q: What is the role I have to give to the lambda in order to be able to submit the batch job?

My lambda gets an AccessDeniedException and fail to submit the job when:

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

Batch.submitJob(params).promise() .then .......
aws-batch aws-lambda roles amazon-web-services

It seems that this was the role I was looking for: batch:SubmitJob. Using this role, the lambda was able to submit the job.

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

You can Create a Policy like AWS Batch Managed Policy,

The following Policy Allows Admin Access,You can modify it as per your needs:

{
    "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*"
            ]
        }
    ]
}

Attach the policy to lambda and try it again , Refer AWS Documentation
