Manage CloudFlow flows with Resource Orchestration Service (ROS)-CloudFlow(CloudFlow)-阿里云帮助中心

Serverless Workflow is integrated with Alibaba Cloud Resource Orchestration Service (ROS). You can use ROS to manage flows. Instead of creating and updating each flow individually, ROS lets you declare flows as infrastructure-as-code in a template and manage their full lifecycle -- create, update, and delete -- through stack operations.

Before you begin

An Alibaba Cloud account with CloudFlow and ROS activated
Familiarity with ROS template syntax and stack operations

ALIYUN::FNF::Flow resource type

Use the ALIYUN::FNF::Flow resource type to declare a CloudFlow flow in a ROS template.

Return values

After the stack is created, retrieve these attributes with Fn::GetAtt:

Attribute	Description
`Id`	The unique identifier of the flow.
`CreatedTime`	The timestamp when the flow was created.
`LastModifiedTime`	The timestamp when the flow was last modified.

Deploy a flow with a ROS template

Both examples below create a flow named test-ros with a single pass step. To deploy a template, create a stack from the ROS console or Alibaba Cloud CLI.

YAML format

ROSTemplateFormatVersion: '2015-09-01'
Resources:
  Flow:
    Type: 'ALIYUN::FNF::Flow'
    Properties:
      # A text description of the flow
      Description: flow created from ros
      # Flow definition in YAML format
      Definition: |-
        version: v1
        type: flow
        steps:
          - type: pass
            name: pass1
      # Flow name
      Name: test-ros
Outputs:
  CreatedTime:
    Description: The flow creation time.
    Value:
      'Fn::GetAtt':
        - Flow
        - CreatedTime
  LastModifiedTime:
    Description: The flow last modified time.
    Value:
      'Fn::GetAtt':
        - Flow
        - LastModifiedTime
  Id:
    Description: The flow ID.
    Value:
      'Fn::GetAtt':
        - Flow
        - Id
