How can i re run user data on aws ec2 from the console?

Question

I would like to ask if there is a way to re-execute user data on a launched instance. I want to restart a service and to edit ~./ssh/autorized_keys.

I found information at https://aws.amazon.com/premiumsupport/knowledge-center/execute-user-data-ec2/ but the cloud log from the console does not show anything to have changed.

Did this using an SSH session. Took a copy of the user data as a script and reran it from the CL.

curl http://instance-data/latest/user-data > user-data.sh
chmod u+x user-data.sh
sudo ./user-data.sh

Just be sure that when you rerun the user-data.sh script that you edit out any commands you might not want to rerun.
