Create an Amazon EKS MNP job definition

To define and run MNP jobs on Amazon EKS, there are new parameters within the RegisterJobDefinition and SubmitJob API operations.

These actions can be defined through API operations and the AWS Management Console.

Reference: Register the Amazon EKS MNP job definition request payload

The following example illustrates how you can register an Amazon EKS MNP job definition with two nodes.

{
  "jobDefinitionName": "MyEksMnpJobDefinition",
  "type": "multinode",
  "nodeProperties": {
    "numNodes": 2,
    "mainNode": 0,
    "nodeRangeProperties": [
      {
        "targetNodes" : "0:",
        "eksProperties": {
          "podProperties": {
            "containers": [
              {
                "name": "test-eks-container-1",
                "image": "public.ecr.aws/amazonlinux/amazonlinux:2",
                "command": [
                  "sleep",
                  "60"
                ],
                "resources": {
                  "limits": {
                    "cpu": "1",
                    "memory": "1024Mi"
                  }
                },
                "securityContext":{
                  "runAsUser":1000,
                  "runAsGroup":3000,
                  "privileged":true,
                  "readOnlyRootFilesystem":true,
                  "runAsNonRoot":true
               }
              }
            ],
            "initContainers": [
               {
                  "name":"init-ekscontainer",
                  "image": "public.ecr.aws/amazonlinux/amazonlinux:2",
                  "command": [
                     "echo",
                     "helloWorld"
                   ],
                   "resources": {
                     "limits": {
                       "cpu": "1",
                       "memory": "1024Mi"
                     }
                  }
               }
            ],
            "metadata": {
               "labels": {
                  "environment" : "test"
               }
            }
          }
        }
      }
    ]
  }
}

To register the job definition using the AWS CLI, copy the definition to a local file named MyEksMnpJobDefinition.json and run the following command.

aws batch register-job-definition --cli-input-json file://MyEksMnpJobDefinition.json

You will receive the following JSON response.

{
    "jobDefinitionName": "MyEksMnpJobDefinition",
    "jobDefinitionArn": "arn:aws:batch:us-east-1:0123456789:job-definition/MyEksMnpJobDefinition:1",
    "revision": 1
}
