从元数据中获取 ec2 实例名称

Question

I need to grab the instance name from EC2 instance for my python script. But stuck how to do that.

My script for other data:

#!/usr/bin/python
from ec2_metadata import ec2_metadata
import sys
print("Region =  " + ec2_metadata.region)

Need something similar to that.

I've tried virtual_name but it is not working.

Answer 1

What do you mean "instance name"?

If it is the first column in the console, try to get the Tags data with "Name" is the key

Answer 2

You have to use boto3 to get the Tags and locate the lone with Name as key:

ec2 = boto3.resource('ec2')
instance = ec2.Instance('intance_id')
print(instance.tags)

Your instance will also need instance role with permissions to interact with ec2.
