Hi all,

I got dynamic inventory for ec2 instances via ansible. But the host in export are all IP addresses.

In ec2.ini

`vpc_destination_variable = private_ip_address`

Sample of dynamic inventory output:

`  
“tag\_Name\_abc01\_example\_com”: [  
“10\_1\_1\_15”  
],

`

So when run playbook, I have limit with it IP address, such as 10\_1\_1\_15

What can I do do to use its tag Name as host in inventory?

In ansible cache, the index is built and archive with private ip address.

“10\_1\_1\_15”: [  
“us-east-2”,  
“i-6652342vs”  
],

You can use in ec2.ini:  
`tag_destination_variable = Name`
