Bundle configuration used for manual testing

bundle:
  name: multiple-tasks

workspace:
  host: ***

environments:
  development: {
    default: true
  }

  production: {}

resources:
  jobs:
    my_job_with_file_task:
      name: "[${bundle.environment}] Job with multiple tasks"

      tasks:
        - task_key: Task1
          existing_cluster_id: ***
          spark_python_task:
            python_file: ./test.py

        - task_key: Task2
          depends_on:
            - task_key: Task1
          existing_cluster_id: ***
          spark_python_task:
            python_file: ./test.py

        - task_key: Task3
          depends_on:
            - task_key: Task2
          existing_cluster_id: ***
          spark_python_task:
            python_file: ./test.py

        - task_key: Task4
          depends_on:
            - task_key: Task1
          existing_cluster_id: ***
          spark_python_task:
            python_file: ./test.py

Output

This is the task key so can be named TaskKey instead to mirror the API objects (or simply Key).
