### Using Cloud Init for automation in devstack

I have looked at some similar examples on heat orchestration and cloud config but I still want to make some clarifications. My use case is to build a web application on OpenStack(devstack) that autoscales. I am not sure if I need to install cloud-init on the host OS. Also, I tried some sripts like this #cloud-config apt_update: true apt_upgrade: true

packages: - python-pip - fail2ban - vim hostname: mynode fqdn: mynode.example.com manage_etc_hosts: true

on an ubuntu cloud image (downloaded) from ubuntu repos. This failed ....How can i troubleshoot such failures ? Thanks in advance !!!
