[SOLVED] Cloud-init isn't applied after linked clone of template via API

[florian-n]

Hi,

currently we're trying to create template based clones using Ansible's community.general.proxmox_kvm. To make the clones configurable we stick with cloud-init. We are building the template using a hand rolled Packer configuration which deploys fine (locally as well as in our production cluster).

If we manually create clones (either locally or in the cluster) we are able to provide cloud-init parameters as expected, the new machine boots and everything is set up.

Now if we use the ansible task to set the VMs up, they're getting cloned as expected but no cloud-init parameters except from the hostname are applied. The corresponding "cloud-init analyze show" command shows the cloud-init command runs through without issue.
The cloud-init tab in the Proxmox UI shows no cloud-init settings though - so i somehow guess the cloud-init parameters aren't passed the right way.

Is there any log i'm able to consult to check what request is being issued? I'd appreciate any hint where to look at!

Thank you very much in advance - Florian

Hello,

can you share your Ansible playbooks?

Thanks

Huh - i oversaw i had to manually add a cloud-init after cloning using the UI. I guess it might me be necessary to set the ci up afterwards.

Thank you @TodorPetkov - sure probably you have more insights than me..

I'm unsure if i'm on the right track.

 

[TodorPetkov]

Try to add "update: yes", for example below "memory: xxx" line.

Here is what I use with CentOS7 template - https://gitlab.com/todorpetkov/ansible-proxmox

Note: check https://docs.ansible.com/ansible/latest/collections/community/general/proxmox_kvm_module.html , "update" parameter section - it does not update several parameters by default.

Thank you very much @TodorPetkov - this option was exactly what i was missing.

I moved the cloud-init based attributes to the update-task. It was important to remove the state attribute from the update-task, i guess the "proxmox_kvm" module should have better eliminated the update attribute and incorporated it into the state attribute.

I leave my tasks here for future interested readers:
