Argo Workflow执行PowerShell脚本报错，请求协助排查修复

错误原因 #

报错Exec format error是因为Argo生成的临时脚本/argo/staging/script未指定解释器，系统尝试直接执行时无法识别其格式；同时原配置中command: ["pwsh", -c]存在YAML语法错误（-c未加引号），且配置逻辑不符合Argo Script模板的执行规则。

修复方案 #

方案一：添加PowerShell Shebang行 #

在脚本开头加入#!/usr/bin/env pwsh，明确指定脚本解释器，无需额外配置command：

apiVersion: argoproj.io/v1alpha1
kind: Workflow
metadata:
  name: powershell-002
  namespace: argo-workflows
spec:
  entrypoint: run-powershell
  templates:
    - name: run-powershell
      script:
        image: mcr.microsoft.com/powershell:latest
        source: |
          #!/usr/bin/env pwsh
          Write-Host "Hello, Argo! This is a PowerShell script."
          $date = Get-Date
          Write-Host "The current date and time is: $date"

方案二：正确配置Command与Args #

通过command指定pwsh解释器，args指定执行临时脚本的参数：

apiVersion: argoproj.io/v1alpha1
kind: Workflow
metadata:
  name: powershell-002
  namespace: argo-workflows
spec:
  entrypoint: run-powershell
  templates:
    - name: run-powershell
      script:
        image: mcr.microsoft.com/powershell:latest
        command: ["pwsh"]
        args: ["/argo/staging/script"]
        source: |
          Write-Host "Hello, Argo! This is a PowerShell script."
          $date = Get-Date
          Write-Host "The current date and time is: $date"

验证方法 #

应用修改后的Workflow配置，执行以下命令查看实时状态：

argo submit -f your-workflow.yaml --watch

若工作流成功执行，会输出PowerShell脚本中的日志内容。
