how to pass in the user-data when launching AWS instances using CLI

Question

I\'m using the AWS CLI to launch instances, and the command is: aws ec2 run-instances

what i\'m expecting is to pass in a script as the user-data. so, I did: DATA=

There is no need to base64 encode the data yourself.

You can prefix a file name/path with file://

So,

aws ec2 run-instances --user-data file://my_script

or

aws ec2 run-instances --user-data file:///full/path/to/my_script
