How to get username in AWS Cloudformation template file?

Question

I have resources defined in my Cloudformation template file with tags defined like so: ``` "Properties": { "Tags": [ { "Key": "Environment", "Value": {"Ref": "Environment"}}, { "Key": "Hello", "Value": "World"} ] } ``` My IAM username is `my.name`. I would like to add a key named `Creator` to the `Tags` property with value my username (`my.name`). Moreover, I need this value to reflect the username of whoever runs this Cloudformation template. How can I do it?

Accepted Answer

I am not aware of any way of referencing the IAM username directly from the template JSON.

However, you can use get-user to get the username (either using the CLI or one of the SDKs), and then pass it on to CloudFormation as a parameter, or, if you are creating the template JSON programmatically, just insert it directly.
