带有多个命令行参数的az cli运行命令调用失败
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。众所周知，argparse将输入-/--作为参数名称。在az cli的--parameters中传递此错误会引发奇怪的错误。

如何使用az run-command invoke
一些示例尝试并输出
尝试-1

直接VM CLI尝试
并且，为了确认这一点，当我在CLI中运行它们时，同一命令可以完美执行
/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

答案 0 :(得分：1)
@kumar_m_kiran-请尝试一下，让我知道它是否有效：
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"
可能您需要在开始时使用“ python”关键字运行脚本。您还可以在scripts参数本身内提供脚本的所有参数。
答案 1 :(得分：1)
有了测试和文档，CLI命令仅在Linux VM中使用--parameters运行带有参数的shell脚本。您可以从Run Shell Script和Available Commands获取详细信息。
运行命令使用VM代理在Azure中运行Shell脚本 Linux VM。
然后使用--debug和结果进行测试：
Shell脚本
Python脚本
过程相同，但shell脚本有效，而python脚本无效。因此，看来您可以使用以下参数将python脚本作为shell脚本运行：
az vm run-command invoke --resource-group groupName \
--name vmName --command-id RunShellScript \
--scripts "python /path/test.py arg1 arg2 arg3"
