Hi All,

I am trying to retrieve the Instance ID of the newly created EC2 instance.

But I get below error:

`

ok: [localhost] =\> {  
“stack\_details.stackoutputs.InstanceId”: “VARIABLE IS NOT DEFINED!”  
}

`

Below is the playbook:

Without the output of  
- debug: var=stack\_details

there isn't mush we can do.

Hi Kai,

Below is the output of

- debug: var=stack\_details

`

ok: [localhost] =\> {  
“stack\_details”: {  
“changed”: true,  
“events”: [  
“StackEvent AWS::CloudFormation::Stack mywindowsec2 CREATE\_COMPLETE”,  
“StackEvent AWS::EC2::Instance Windows2016EC2 CREATE\_COMPLETE”,  
“StackEvent AWS::EC2::Instance Windows2016EC2 CREATE\_IN\_PROGRESS”,  
“StackEvent AWS::EC2::Instance Windows2016EC2 CREATE\_IN\_PROGRESS”,  
“StackEvent AWS::CloudFormation::Stack mywindowsec2 CREATE\_IN\_PROGRESS”  
],  
“failed”: false,  
“log”: ,  
“output”: “Stack CREATE complete”,  
“stack\_outputs”: {  
“InstanceId”: “i-0a913dd7c9eb45bbe”  
},  
“stack\_resources”: [  
{  
“last\_updated\_time”: “2018-12-08T08:58:44.185000+00:00”,  
“logical\_resource\_id”: “Windows2016EC2”,  
“physical\_resource\_id”: “i-0a913dd7c9eb45bbe”,  
“resource\_type”: “AWS::EC2::Instance”,  
“status”: “CREATE\_COMPLETE”,  
“status\_reason”: null  
}  
]  
}  
}

`

I need only InstanceId from the above.

It's stack\_outputs, but as you see below you used stackoutputs

> \> \> But I get below error:  
> \> \>  
> \> \> ok: [localhost] =\> {  
> \> \> "stack\_details.stackoutputs.InstanceId": "VARIABLE IS NOT DEFINED!"

So the correct variable should be  
stack\_details.stack\_outputs.InstanceId
