如何在启动时通过AWS CLI获取公共IP(How to get Public IP via AWS CLI while launching)

 我的AWS命令是： 
 
> aws ec2 run-instances --image-id ami-346b2354 --count 1 --instance-type c4.large --key-name my-cali-key --security-group-ids sg-a168c7c4
 
 当我触发它时，它返回的JSON数据只有私有IP地址而不是公共IP地址。

                "Groups": [
                    {
                        "GroupName": "launch-wizard-1", 
                        "GroupId": "sg-a168c7c4"
                    }
                ], 
                "SubnetId": "subnet-cb2524ae", 
                "OwnerId": "012710546082", 
                "PrivateIpAddress": "172.31.17.252"
            }

 （图像）使用Public IP浏览器外观相同的实例 
 
 但是，当我在浏览器中看到时，我立即注意到自动关联的公共IP地址。 如何获取已启动实例的公共IP？ 请不要对弹性IP及其与实例的关联感到困惑。 我知道将弹性IP联系起来，但这里的需求是不同的。 

My AWS Command is:
 
> aws ec2 run-instances --image-id ami-346b2354 --count 1 --instance-type c4.large --key-name my-cali-key --security-group-ids sg-a168c7c4
 
When I trigger this, the JSON data that it returns has only the Private IP address and NOT the Public IP address.

                        "GroupId": "sg-a168c7c4"
                    }

(Image) Browser look of the same instance with Public IP
 
However when I see in the browser I immediately notice a Public IP address being associated automatically. How Can I fetch the public IP of launched instances? Kindly do not get confused with elastic-IP and its association with instances. I know to associate an elastic-IP but the need here is different.
