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.

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

  
 { 
  
 "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.
