我有docker ps命令的以下输出：
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES e1d52c0adee7 share-platform:6000/share-platform:1.0.96-windowsservercore "powershell -Command…" 3 months ago Up 2 weeks share-platform ad6a8e2c7fd0 prism:6000/prism-platform:1.0.1078-windowsservercore "powershell -Command…" 3 months ago Up 2 months 9080/tcp prism-platform efd847643e86 mongo:6000/mongo:3.2-windowsservercore "mongod --smallfiles…" 3 months ago **Restarting (100) 2 weeks ago** 27017/tcp mongo 3d8ab9b5c36e share:6000/share-app:1.0.153-windowsservercore "powershell -Command…" 3 months ago Up 2 months share-app dc4b1053d9da prism-app:6000/prism-app:1.0.4183.1-windowsservercore "powershell -Command¦" 3 months ago Up 2 months prism-app 2a38e006f85f core:6000/welcome:1.0.241.1-windowsservercore "powershell -Command¦" 3 months ago Up 2 months
我试图循环输出中的状态列，如果有UP以外的状态，我想回应它。
我尝试将其导出到csv，然后使用Import-Csv。可以预期的是，由于MongoDB状态不是Up，我希望它将它回显到屏幕上，如“Mongo is not Up”（从NAMES列获取名称）。
脚本的实际结果为空白。
docker ps | out-file D:\temp\PAW_ps.csv
$csv = Import-Csv D:\Temp\PAW_ps.csv
foreach ($row in $csv)
{
$name = $row.NAMES
$status = $row.STATUS
if ($status -ne "UP")
{
echo "The process $name is not Up"
}

您不需要导出和导入您尝试使用的数据。
一个快速的伪代码示例：
docker ps | ForEach-Object {
if ($_.STATUS -ne "UP") {
Echo "The process $($_.NAMES) is not up"
}
}
