我创建了一个WorkflowTemplate，其中我想将脚本模板的结果作为输入参数传递给另一个任务

这是我的WorkflowTemplate

apiVersion: argoproj.io/v1alpha1
kind: WorkflowTemplate
metadata:
  name: dag-wft
spec:
  entrypoint: whalesay
  templates:
  - name: whalesay
    inputs:
      parameters:
        - name: message
          default: '["tests/hello", "templates/hello", "manifests/hello"]'
    dag:
      tasks:
        - name: prepare-lst
          template: prepare-list-script
          arguments:
            parameters:
              - name: message
                value: "{{inputs.parameters.message}}"

        - name: templates
          depends: prepare-lst
          templateRef:
            name: final-dag-wft
            template: whalesay-final
          arguments:
            parameters:
            - name: fnl_message
              value: "{{item}}"
          withParam: "{{tasks.prepare-lst.outputs.parameters.templates_lst}}"

        - name: manifests
          depends: prepare-lst && (templates.Succeeded || templates.Skipped)
          templateRef:
            name: final-dag-wft
            template: whalesay-final
          arguments:
            parameters:
            - name: fnl_message …

我有两个工作流程模板generate-output和lib-read-outputs一个工作流程，output-paramter如下所示

1. generate-output.yaml

apiVersion: argoproj.io/v1alpha1
kind: WorkflowTemplate
metadata:
  name: generate-output
spec:
  entrypoint: main
  templates:
    - name: main
      dag:
        tasks:

          # Generate Json for Outputs
          - name: read-outputs
            arguments:
              parameters:
                - name: outdata
                  value: |
                    {
                      "version": 4,
                      "terraform_version": "0.14.11",
                      "serial": 0,
                      "lineage": "732322df-5bd43-6e92-8f46-56c0dddwe83cb4",
                      "outputs": {
                        "key_alias_arn": {
                          "value": "arn:aws:kms:us-west-2:123456789:alias/tetsing-key",
                          "type": "string",
                          "sensitive": true
                        },
                        "key_arn": {
                          "value": "arn:aws:kms:us-west-2:123456789:alias/tetsing-key",
                          "type": "string",
                          "sensitive": true
                        }
                      }
                    }
            template: retrieve-outputs

    # Create Json
    - name: retrieve-outputs
      inputs:
        parameters: …

我有一个工作流程，其中使用jsonpath输出参数的函数从 json 字符串中提取特定值，但由于此错误而失败Error (exit code 255)

这是我的工作流程

apiVersion: argoproj.io/v1alpha1
kind: Workflow
metadata:
  generateName: wf-dev-
spec:
  entrypoint: main
  templates:
    - name: main

      dag:
        tasks:
          - name: dev-create
            templateRef:
              name: dev-create-wft
              template: main
            arguments:
              parameters:
                - name: param1
                  value: "val1"

          - name: dev-outputs
            depends: dev-create.Succeeded
            templateRef:
              name: dev-outputs-wft
              template: main
            arguments:
              parameters:
                - name: devoutputs
                  value: "{{=jsonpath(tasks.dev-create.outputs.parameters.devoutputs, '$.alias.value')}}"

在上面的工作流任务中dev-create调用另一个工作流模板dev-create-wft，它返回另一个工作流模板的输出

这是我的工作流程模板

apiVersion: argoproj.io/v1alpha1
kind: WorkflowTemplate
metadata:
  name: dev-create-wft

spec:
  entrypoint: main
  templates:
    - name: main
      outputs: …

如果字符串以特定子字符串开头，我想在 Argo 工作流程中执行任务。例如，我的字符串是tests/dev-or.yaml，如果我的字符串以以下开头，我想执行任务tasks/

这是我的工作流程，但条件没有得到正确验证

apiVersion: argoproj.io/v1alpha1
kind: Workflow
metadata:
  generateName: conditional-
spec:
  entrypoint: conditional-example
  arguments:
    parameters:
    - name: should-print
      value: "tests/dev-or.yaml"

  templates:
  - name: conditional-example
    inputs:
      parameters:
      - name: should-print
    steps:
    - - name: print-hello
        template: whalesay
        when: "{{inputs.parameters.should-print }} startsWith 'tests/'"

  - name: whalesay
    container:
      image: docker/whalesay:latest
      command: [sh, -c]
      args: ["cowsay hello"]

以下是我运行工作流程时出现的错误

WorkflowFailed 7s workflow-controller  Invalid 'when' expression 'tests/dev-or.yaml startsWith 'tests/'': Unable to access unexported field 'yaml' in token 'or.yaml'

似乎它不接受-, .yaml …
