使用多个命令行参数的 az cli run-command 调用失败

Question

我正在尝试使用命令行参数执行远程 python 脚本。 python 脚本是使用 argparse 开发的。正如我们所知，argparse 以-/-- 作为参数名称的输入。在 az cli 的 --parameters 中传递它会引发奇怪的错误。

问题 如何使用az run-command invoke为python脚本传递类似python argparse的参数

直接 VM CLI 尝试

而且，为了确认，当我在 CLI 中运行相同的命令时，它们可以完美执行

/mnt/workspace/scripts/test.py -i /mnt/workspace/data/indata -o /mnt/workspace/data/outdata --input_compressed_data --output_compressed_data -a 600 -p 0.1 -b 600 1200 1800  -s 1543275000

Answer 1

@kumar_m_kiran - 请尝试一下，如果可行，请告诉我：

az vm run-command invoke     --resource-group MDC_VME_DEV_EUS  \
   --name ubuntumemsql002     --command-id RunShellScript  \
   --scripts "python /mnt/workspace/scripts/test.py -i /mnt/workspace/data/indata -o /mnt/workspace/data/outdata --input_compressed_data --output_compressed_data -a 600 -p 0.1 -b 600 1200 1800 -s 1543275000"

您可能需要在开始时使用“python”关键字运行脚本。您还可以在脚本参数本身中提供脚本的所有参数。

Answer 2

通过测试和文档，CLI 命令只需在 Linux VM 中使用 --parameters 的参数运行 shell 脚本。您可以从Run Shell Script 和Available Commands 获取详细信息。

Run Command 使用 VM 代理在 Azure 中运行 shell 脚本 Linux 虚拟机。

然后用--debug 测试，结果在这里：

Shell 脚本 Python 脚本

过程相同，但 shell 脚本有效，python 脚本无效。因此，您似乎可以将 python 脚本作为 shell 脚本运行，参数如下：

az vm run-command invoke     --resource-group groupName  \
   --name vmName             --command-id RunShellScript  \
   --scripts "python /path/test.py arg1 arg2 arg3"
