azure - 将 azure 文件共享安装到 azure devops 管道的速度非常慢

Question

目前，我需要大约一分钟才能将 azure 文件共享挂载到 azure DevOps 管道。我想，这太长了。我的管道包含安装操作的两个步骤:检索凭据和安装。

这就是我的管道的样子:

- task: AzureCLI@2
      inputs:
        azureSubscription: 'My Resource Group'
        scriptType: 'ps'
        scriptLocation: 'inlineScript'
        inlineScript: |
          (get-date).ToString('T')
          $sas_expiry = (Get-Date).AddHours($(storage.sas.expiry_hours)).ToUniversalTime().ToString("yyyy-M-d'T'H:M'Z'")
          echo "Getting keys..."
          (get-date).ToString('T')
          $key=(az storage account keys list --account-name $(storage.account) | jq '.[0].value' -r)
          echo "Keys are here."
          echo "##vso[task.setvariable variable=storage.key;issecret=true]$key"
          (get-date).ToString('T')
          $sas_key=(az storage account generate-sas --account-key $key --account-name $(storage.account) --expiry  $sas_expiry --https-only --permissions acdlpruw --resource-types sco --services f --output tsv)
          echo "##vso[task.setvariable variable=storage.sas.key;issecret=false]$sas_key"
          (get-date).ToString('T')
      displayName: Get azure file share credentials
    - task: PowerShell@2
      inputs:
        targetType: 'inline'
        script: |
          $connectTestResult = Test-NetConnection -ComputerName mystorage.file.core.windows.net -Port 445
          if ($connectTestResult.TcpTestSucceeded) {
              cmd.exe /C "cmdkey /add:`"mystorage.file.core.windows.net`" /user:`"Azure\$(storage.account)`" /pass:`"$(storage.key)`""
              # Mount the drive
              New-PSDrive -Name $(storage.drive) -PSProvider FileSystem -Root "$(storage.unc)" -Persist
              dir z:
          }
          else {
              Write-Error -Message "Unable to reach the Azure storage account via port 445. Check to make sure your organization or ISP is not blocking port 445, or use Azure P2S VPN, Azure S2S VPN, or Express Route to tunnel SMB traffic over a different port."
          }
      displayName: "Mount azure file share to Z"

...我显然添加了一些时间戳输出以便于“分析”。这是日志记录。

Finishing: Mount azure file share to Z

所有这些都在默认的 Microsoft Azure 托管代理上运行。我该怎么做才能更快地装载文件共享？

Answer 1

检查az cli的任务日志，它实际上调用了powershell.exe来执行az cli任务中的脚本。

因此可以将powershell任务中的脚本合并到az cli任务中。

在一个任务中执行脚本应该比在两个任务中执行脚本更快。
