Question On Cloud-init and ConfigDrive

brodiecyber

Hello

I was finally been able to get cloud-init working. But i have a question that i can seem to find and answer to

Must the cloud config drive be permanently attached to the VM to preserve Network configurations? As my custom template applies the network config but when i remove the drive it defaults back to DHCP

Ive removed removed the network configurations in the /etc/network/interfaces file except for the eth0 hotplug and well as details in the hosts file

This is my cloud config

#Cloud-config
users:
   - default

disable_root: true

#Set hostname
preserve_hostname: false
hostname: debian-localhost
manage_resolv_conf: true
manage_etc_hosts: true
apt_preserve_sources_list: true
