I've got a custom hardended RHEL 7.5 custom AMI. I want to use user data to complete some deploy time configuration. I've already ensured that /var/lib/cloud/* is removed before I create the AMI.
These are the contents of my user data:
echo "My script fired." >> /tmp/test.txt
echo "This line should produce an output log."
The file /tmp/test.txt is present, indicating the my script did indeed run. However, the expected result of the second statement is that a file /var/log/cloud-init-output.log should be produced in accordance with the AWS docs. This file is not present.
How do I make sure that user data produces the expected output log file?
