在给定实例ID的情况下检索EC2实例的IP地址

Question

使用aws CLI,如何在给定其instanceID的情况下检索EC2实例的私有IP地址？

当我做:

aws ec2 describe-instance-status --instance-ids <instance_ID>

我得到其他信息,但不是私有IP地址,例如:

{
    "InstanceStatuses": [
        {
            "InstanceId": "XXXXX", 
            "InstanceState": {
                "Code": 16, 
                "Name": "running"
            }, 
            "AvailabilityZone": "us-east-1a", 
            "SystemStatus": {
                "Status": "ok", 
                "Details": [
                    {
                        "Status": "passed", 
                        "Name": "reachability"
                    }
                ]
            }, 
            "InstanceStatus": {
                "Status": "ok", 
                "Details": [
                    {
                        "Status": "passed", 
                        "Name": "reachability"
                    }
                ]
            }
        }
    ]
}

Answer 1

试试吧describe-instances.不会使用describe-instance-status返回专用IP地址,因为该命令描述了系统和实例状态,主要与硬件/问题或预定事件有关.

根据describe-instances文档的"输出"部分,describe-instances的部分输出是一个字符串PrivateIpAddress.

用法示例:

aws ec2 describe-instances --instance-ids <instance_ID>

Answer 2

要获取所有私有 IP 地址：

aws ec2 describe-instances --instance-ids ${INSTANCE_ID} |\
jq -r '.Reservations[].Instances[].NetworkInterfaces[].PrivateIpAddress'

或者

aws ec2 describe-instances --instance-ids ${INSTANCE_ID} |\
jq -r ".Reservations[]" | grep PrivateIpAddress |\
egrep -o "([0-9]{1,3}\.){3}[0-9]{1,3}" | sort -u
