AWS Solutions Architect and IT Consultant is one of my Foundry servers running on K3s, launched in Proxmox VE using Terraform and Ansible in my Gitlab using the multinic cloud init image. I used the Helm chart with my docker image of Foundry.

I was able to do a good test of the K3 ansible script with my Multi Nic Terraform for Prox Mox that gave me an external static IP address. It is a 2 node K3 cluster,

Cloud images inherently come with one NIC. Once you create you cloud init image below create it in ProxMox as a machine, not a template and run it. This multi-nic image works for other providers as well. You will want to install netplugd to make this work.

sudo apt-get install netplug


sudo mv netplug /etc/netplug/netplug

sudo chmod +/etc/netplug/netplug

Spin up the machine and add an extra network port in Proxmox and test it if you want. Otherwise you can turn it into a template.

Cloud init images are great for ProxMox Templates and for launching machines via Terraform. 

This code is also available here:

Ubuntu images are available here:


You need to install libguestfstools to customize the image.

sudo apt update -y && sudo apt install libguestfs-tools -y

 Once the tools are installed you can start customizing your image:

sudo virt-customize -a focal-server-cloudimg-amd64.img --install qemu-guest-agent
sudo virt-customize -a focal-server-cloudimg-amd64.img --run-command 'useradd pmatra'
sudo virt-customize -a focal-server-cloudimg-amd64.img --run-command 'mkdir -p /home/pmatra/.ssh'
sudo virt-customize -a focal-server-cloudimg-amd64.img --ssh-inject pmatra:file:/home/pmatra/.ssh/authorized_keys
sudo virt-customize -a focal-server-cloudimg-amd64.img --run-command 'chown -R pmatra:pmatra /home/pmatra'
sudo virt-customize -a focal-server-cloudimg-amd64.img --root-password password:PASSWORD
sudo virt-customize -a focal-server-cloudimg-amd64.img --run-command 'echo /etc/sudoers >> pmatra ALL=(ALL) NOPASSWD:ALL'

After all of that is done if you want to load it into Proxmox as a template, you need to upload it to your Proxmox Server and run this code.

qm create 9000 --name "ubuntu20-cloudinit-template" --memory 2048 --cores 2 --net0 virtio,bridge=vmbr0
qm importdisk 9000 focal-server-cloudimg-amd64.img local-lvm
qm set 9000 --scsihw virtio-scsi-pci --scsi0 local-lvm:vm-9000-disk-0
qm set 9000 --boot c --bootdisk scsi0
qm set 9000 --ide2 local-lvm:cloudinit
qm set 9000 --serial0 socket --vga serial0
qm set 9000 --agent enabled=1
qm template 9000

If you want to clone the image manually you can do it this way via ProxMox Shell or SSH

sudo qm clone 9000 999 --name test-clone-cloud-init sudo qm set 999 --ipconfig0 ip=,gw= sudo qm start 999
