I've the following file in my cloud-init
write_files:
- path: /opt/data/conf.conf
owner: root:root
permissions: '0755'
content: |
[default]
host = $HOSTNAME
I need to interpolate properly the variable $HOSTNAME when it is executed in an EC2 instance.
I didn't find anything about that in the documentation but I found EC2 datasource.
Any idea how to properly interpolate that value?
The quick idea I had is to write it inside an executable and interpolate from there. is it the only way?
