Proxmox VM Templates

Before Terraform can create virtual machines, we need to prepare templates that Terraform can then clone.

Example: Ubuntu 20.04 Template

# SSH into the PVE host

# download the cloud-init iso (Openstack ready cloud-init images)
$ cd /var/lib/vz/template/iso/
$ wget https://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64.img

# Set vmid to use
$ export VM_ID="1002"

# create vm and import the iso image (cqow2 format)
$ qm create $VM_ID \
    --name template-ubuntu-2004-focal-fossa \
    --ostype l26 \
    --memory 1024 \
    --sockets 1 \
    --cores 1 \
    --vcpu 1  \
    --numa 1 \
    --net0 virtio,bridge=vmbr42 \
    --agent 1

$ qm importdisk $VM_ID focal-server-cloudimg-amd64.img local --format qcow2

# set some options
$ qm set $VM_ID --scsihw virtio-scsi-pci
$ qm set $VM_ID --virtio0 local:$VM_ID/vm-$VM_ID-disk-0.qcow2
$ qm set $VM_ID --ide2 local:cloudinit
$ qm set $VM_ID --boot c --bootdisk virtio0
$ qm set $VM_ID --serial0 socket
$ qm set $VM_ID --hotplug network,disk,cpu,memory,usb

# convert the VM to the template
$ qm template $VM_ID

Terraform

Prepare Terraform

Run this on the Proxmox host:

• Create a Proxmox user for Terraform (commands on Proxmox host cli):

  $ pveum user add terraform@pve --password "some-secure-password"
  $ pveum aclmod / -user terraform@pve -role Administrator

Run this on the machine running Terraform:

• Prepare ssh keypair for the new VM:

  $ ssh-keygen -t rsa -b 4096 -N "" -q -C "terraform-vm" -f ~/.ssh/tf-vm

• Activate logging if you prefer it:

  $ export TF_LOG=1

• Export the terraform user password as environment variable:

  $ export PM_PASS="some-secure-password"

• Run Terraform:

  # Install all providers
  $ terraform init
  
  # Validate files
  $ terraform validate
  
  # Plan / Apply specific OS version
  # terraform apply --var-file=$(pwd)/templates/<OS Template>/vars.tf
  $ terraform apply --var-file=$(pwd)/templates/ubuntu_20.04_focal-fossa/vars.tf
