I’m trying to make a Proxmox Ubuntu Jammy template using Packer and I’ve been struggling to make it work.
Here’s my pkr.hcl file:
# Ubuntu Server jammy
# ---
# Packer Template to create an Ubuntu Server (jammy) on Proxmox
# Variable Definitions
variable "proxmox_api_url" {
type = string
}
variable "proxmox_api_token_id" {
type = string
}
variable "proxmox_api_token_secret" {
type = string
sensitive = true
}
# Resource Definiation for the VM Template
source "proxmox-iso" "ubuntu-server-jammy" {
# Proxmox Connection Settings
proxmox_url = "${var.proxmox_api_url}"
username = "${var.proxmox_api_token_id}"
token = "${var.proxmox_api_token_secret}"
# (Optional) Skip TLS Verification
insecure_skip_tls_verify = true
# VM General Settings
node = "pve01"
vm_id = "30069"
vm_name = "ubuntu-server-jammy"
template_description = "Ubuntu Server jammy Image"
# VM OS Settings
iso_url = "https://releases.ubuntu.com/22.04.2/ubuntu-22.04.2-live-server-amd64.iso"
iso_checksum = "5e38b55d57d94ff029719342357325ed3bda38fa80054f9330dc789cd2d43931"
iso_storage_pool = "local"
unmount_iso = true
# VM System Settings
qemu_agent = true
# VM Hard Disk Settings
scsi_controller = "virtio-scsi-pci"
disks {
disk_size = "20G"

type = "virtio"
}
# VM CPU Settings

# VM Memory Settings
memory = "4096"
# VM Network Settings
network_adapters {
model = "virtio"
bridge = "vmbr0"
firewall = "false"
}
# VM Cloud-Init Settings
cloud_init = true
cloud_init_storage_pool = "local-zfs"
# PACKER Boot Commands
boot_command = [
"<esc><wait>",

]

# http_port_max = 8802
ssh_username = "root"
ssh_private_key_file = "~/.ssh/id_rsa"
ssh_timeout = "20m"
}
# Build Definition to create the VM Template
build {
name = "ubuntu-server-jammy"
sources = ["source.proxmox-iso.ubuntu-server-jammy"]
# Provisioning the VM Template for Cloud-Init Integration in Proxmox #1
provisioner "shell" {
inline = [
"while [ ! -f /var/lib/cloud/instance/boot-finished ]; do echo 'Waiting for cloud-init...'; sleep 1; done",
"sudo rm /etc/ssh/ssh_host_*",
"sudo truncate -s 0 /etc/machine-id",
"sudo apt -y autoremove --purge",
"sudo apt -y clean",
"sudo apt -y autoclean",
"sudo cloud-init clean",
"sudo rm -f /etc/cloud/cloud.cfg.d/subiquity-disable-cloudinit-networking.cfg",
"sudo rm -f /etc/netplan/00-installer-config.yaml",
"sudo sync"
]
}
# Provisioning the VM Template for Cloud-Init Integration in Proxmox #2
provisioner "file" {
source = "files/99-pve.cfg"
destination = "/tmp/99-pve.cfg"
}
# Provisioning the VM Template for Cloud-Init Integration in Proxmox #3
provisioner "shell" {
inline = [ "sudo cp /tmp/99-pve.cfg /etc/cloud/cloud.cfg.d/99-pve.cfg" ]
}
# Add additional provisioning scripts here
# ...
}
And I also have a user-data file under http folder :
#cloud-config
autoinstall:
version: 1
locale: en_US
keyboard:
layout: fr
ssh:
install-server: true
allow-pw: true
disable_root: true
ssh_quiet_keygen: true
allow_public_ssh_keys: true
packages:
- qemu-guest-agent
- sudo
storage:
layout:
name: direct
swap:
size: 0
user-data:
package_upgrade: false
timezone: Europe/Paris
users:
- name: root
groups: [adm, sudo]
lock-passwd: false
sudo: ALL=(ALL) NOPASSWD:ALL
shell: /bin/bash
ssh_authorized_keys:
- ssh-rsa ...
The public ssh key provided in ssh_authorized_keys is one that has been generated using the private key in the file specified in ssh_private_key_file.
After few minutes on launching the build, the client side gets stuck in this step:
ares@ares:~/dev/devops/homelab/packer/ubuntu_server_jammy_yt$ packer build -var-file=./credentials.pkr.hcl ubuntu-server-jammy.pkr.hcl
ubuntu-server-jammy.proxmox-iso.ubuntu-server-jammy: output will be in this color.

The Proxmox Template Console is stuck in this part:
Does anyone have any idea of what I’m doing wrong ?
EDIT:
I’ve added authorized-keys in user-data file under ssh section and got the SSH part working.
I’m having another error now :
