# Setup AWS Batch

1. Create a Compute Environment

2. Create AWS Batch Queue(s)
https://aws.amazon.com/getting-started/hands-on/run-batch-jobs-at-scale-with-ec2-spot/
1. Update IAM Role trust policy:
https://docs.aws.amazon.com/batch/latest/userguide/execution-IAM-role.html
1. Allow propeller's IAM Role to passRole:
https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use_passrole.html
3. Update Admin Config:

  flyteadmin:
    roleNameKey: "eks.amazonaws.com/role-arn"
  queues:
    executionQueues:
        # The name of the job queue from AWS Batch
      - dynamic: "tutorial"
        attributes:
          - default
    workflowConfigs:
      - tags:
          - default

4. Update propeller config:

    plugins:
      aws:
        batch:
          roleAnnotationKey: eks.amazonaws.com/role-arn
        region: us-east-2
    tasks:
      task-plugins:
        enabled-plugins:
          - aws_array
        default-for-task-types:
          container_array: aws_array

5. Retrieve a launchplan's execution file:

   flytectl --config ~/.flyte/flytectl.yaml get launchplan -p flytesnacks -d development core.control_flow.map_task.my_map_workflow --version 64de460a657141927b8867a181b92d82e14aa832 --execFile ~/map_wf.yaml

6. Fill in `iamRoleARN` (mandatory for AWS Batch) and `kubeServiceAcct` (optional if you use Identity )
