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.

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"
        },

It's stack_outputs, but as you see below you used stackoutputs

So the correct variable should be
stack_details.stack_outputs.InstanceId
