I am having a problem with my VyOS cloud VM image where it does not run the userdata script. Firstly, I created my VyOS using the Ansible scripts from vyos-vm-images GitHub page with the following command-line arguments:
ansible-playbook qemu.yml -e disk_size=3 -e cloud_init=true -e cloud_init_ds=ConfigDrive,DigitalOcean,NoCloud,None -e keep_user=true -e enable_ssh=true -e parttable_type=mbr
After that, I uploaded it to DigitalOcean and started a new Droplet with a small userdata script to see if it works. The script is from the official documentation of VyOS on Cloud-Init with a tweak to work on DigitalOcean metadata API.
#cloud-config
write_files:
- path: /opt/vyatta/etc/config/scripts/vyos-postconfig-bootup.script
owner: root:vyattacfg
permissions: '0775'
content: |
#!/bin/vbash
source /opt/vyatta/etc/functions/script-template
hostname=$(curl -s http://169.254.169.254/metadata/v1/hostname)
configure
set system host-name $hostname
commit
exit
The script does not run at all as the VM hostname has not been changed even after a restart. However, I did notice that the userdata was written to /opt/vyatta/etc/config/cloud/instances/400456035/user-data.txt for some reason but Cloud-Init didn’t use it. When I look into the log file of Cloud-Init at /var/log/cloud-init.log, there is only a mention of userdata not being found. I have attached the full content of this file as attachment if you want to delve deeper.

I am not very familiar with Cloud-Init and this is my first time trying out on a cloud. Please let me know if I can provide any more information. Any help is appreciated!
