Main workflow

A workflow source file can contain only one main workflow and, as a best practice, we recommend placing your main workflow in a main block.

If a workflow has a subworkflow, the main workflow must be placed in a main block. Similarly, for a workflow to receive runtime arguments there must be a main block.

YAML

  main:
      params: [MAP_NAME]
      steps:
          - STEP_NAME:
              ...
          ...

JSON

    {
      "main": {
        "params": [
          "MAP_NAME"
        ],
        "steps": [
          {
            "STEP_NAME": {
              ...
            }
          },
          ...
        ]
      }
    }

Inside the main workflow, you can define the steps you want and their order of execution using the Workflows syntax. Every workflow must have at least one step.
