下面的函数以及我在脚本中用于收集我们在 AWS 中的所有内容的完整清单的其他函数，运行没有任何问题。

但是，当实例具有多个接口时，我缺少在第一个 IP 地址之后分配给该实例的所有 IP 地址。

在将详细信息写入 Excel 工作表之前，如何确保在下面的函数中获取每个实例的所有 IP 地址？

function Create-EC2InstanceWorksheet {

 #Creating EC2 Instances Worksheet

        # Add Excel worksheet
        $workbook.Worksheets.Add()

        # We need to create a sheet for the Instances
        $InstancesWorksheet = $workbook.Worksheets.Item(1)
        $InstancesWorksheet.Name = 'Instances'

        # Headers for the Instance worksheet
        $InstancesWorksheet.Cells.Item(1,1) = 'Region'
        $InstancesWorksheet.Cells.Item(1,2) = 'Instance Name'
        $InstancesWorksheet.Cells.Item(1,3) = 'Image ID'
        $InstancesWorksheet.Cells.Item(1,4) = 'Instance ID'
        $InstancesWorksheet.Cells.Item(1,5) = 'PEM File'
        $InstancesWorksheet.Cells.Item(1,6) = 'Instance Type'
        $InstancesWorksheet.Cells.Item(1,7) = 'Private IP'
        $InstancesWorksheet.Cells.Item(1,8) = 'Public IP'
        $InstancesWorksheet.Cells.Item(1,9) = 'VPC ID'
        $InstancesWorksheet.Cells.Item(1,10) = 'Subnet ID'
        $InstancesWorksheet.Cells.Item(1,11) = 'State'
        $InstancesWorksheet.Cells.Item(1,12) = 'Security Group Id'
        $InstancesWorksheet.Cells.Item(1,13) = 'Source/Dest Check'

        # Excel Cell Counter
        $row_counter = 3
        $column_counter = 1



    # Get the Ec2 instances for each region
    foreach($AWS_Locations_Iterator in $AWS_Locations){
        $EC2Instances = Get-EC2Instance -Region $AWS_Locations_Iterator

        # Iterating over each instance

foreach($EC2Instances_Iterator.Instances.NetworkInterfaces.PrivateIpAddresses.PrivateIpAddress in $EC2Instances){

foreach($EC2Instances_Iterator.Instances.NetworkInterfaces.Pr ... + ~ 在 foreach 循环中的变量后缺少“in”。

从 foreach 开始删除上面的代码，并使用@AnthonyNeace 提供的建议。替换为下面的 foreach，它确实提供了额外的 IP 地址。

        foreach($instance in $EC2Instances.Instances){
            foreach($networkInterface in $instance.NetworkInterfaces){
            "$($instance.InstanceID): $($networkInterface.PrivateIpAddresses.PrivateIpAddress)";



            # Ignore if a region does not have any instances
            if($EC2Instances_Iterator.count -eq $null) {
            continue
            }
            # Populating the cells
            $InstancesWorksheet.Cells.Item($row_counter,$column_counter++) = $AWS_Locations_Iterator
            $InstancesWorksheet.Cells.Item($row_counter,$column_counter++) = $EC2Instances_Iterator.Instances.Tags.value
            $InstancesWorksheet.Cells.Item($row_counter,$column_counter++) = $EC2Instances_Iterator.Instances.imageid
            $InstancesWorksheet.Cells.Item($row_counter,$column_counter++) = $EC2Instances_Iterator.Instances.Instanceid
            $InstancesWorksheet.Cells.Item($row_counter,$column_counter++) = $EC2Instances_Iterator.Instances.keyname.tostring()
            $InstancesWorksheet.Cells.Item($row_counter,$column_counter++) = $EC2Instances_Iterator.Instances.Instancetype.Value
            $InstancesWorksheet.Cells.Item($row_counter,$column_counter++) = $EC2Instances_Iterator.Instances.PrivateIpAddress
            $InstancesWorksheet.Cells.Item($row_counter,$column_counter++) = $EC2Instances_Iterator.Instances.PublicIpAddress
            $InstancesWorksheet.Cells.Item($row_counter,$column_counter++) = $EC2Instances_Iterator.Instances.VpcId
            $InstancesWorksheet.Cells.Item($row_counter,$column_counter++) = $EC2Instances_Iterator.Instances.SubnetId
            $InstancesWorksheet.Cells.Item($row_counter,$column_counter++) = $EC2Instances_Iterator.Instances.state.name.value
            $InstancesWorksheet.Cells.Item($row_counter,$column_counter++) = $EC2Instances_Iterator.Instances.securitygroups.GroupId
            $InstancesWorksheet.Cells.Item($row_counter,$column_counter++) = $EC2Instances_Iterator.Instances.SourceDestCheck


            # Seting the row and column counter for next EC2 instance entry
            $row_counter = $row_counter + 1
            $column_counter = 1
        }

        # Iterating to the next region
        $row_counter = $row_counter + 1
    }

}

网络接口包含在 Get-EC2Instance 响应中的每个 EC2 实例中，因此以私有 IP 地址为例……您可以通过简单地遍历每个网络接口上公开的每个私有 IP 地址来访问私有 IP 地址。IPv6 地址也一样。

对象模型

IPv4 示例

$EC2Instances_Iterator.Instances.NetworkInterfaces.PrivateIpAddresses.PrivateIpAddress

IPv6 示例

$EC2Instances_Iterator.Instances.NetworkInterfaces.Ipv6Addresses.Ipv6Address

示例：使用 foreach 循环写入地址字符串

此示例将跨每个网络接口的地址构建为实例循环范围内的逗号分隔字符串。因此，为每个实例创建一个字符串。

powershell子表达式运算符 $()用于解析字符串中的复杂属性。

$EC2Instances = Get-EC2Instance

foreach($instance in $EC2Instances.Instances){
  $addresses = "";
  foreach($networkInterface in $instance.NetworkInterfaces){
    $addresses = $addresses, $networkInterface.PrivateIpAddresses.PrivateIpAddress -join ","
  }
  "$($instance.InstanceID): $($addresses.Trim(','))"    
}
