How is cloud-init working at all?

[prologic]

Okay, let's leave #274 alone for the moment...

I have created a very simple template using Packer and that has worked, I can clone that as a new VM.

Here is now my main.tf using this provider:

resource "proxmox_vm_qemu" "cloudinit-test" {
  name = "tftest1"
  target_node = "vz1"

  clone = "burmilla-1-9-2-amd64"

  disk {
    storage = "zfs"
    type = "scsi"
    size = "60G"
  }

  cores = 2
  sockets = 1
  memory = 2048

  network {
    model = "virtio"
    bridge = "vmbr0"
  }

  ssh_user = "rancher"

  os_type = "cloud-init"
  ipconfig0 = "ip=dhcp"

  sshkeys = <<EOF
ssh-rsa xxx 
EOF
}

This gets created and boots just fine, but I don't see a CloudDrive created for it or anything under the "Cloud-init" section for that VM in the Proxmox VE.

What's going on here? Where is that sshkeys going here? I'm happy to debug this, but the docs are very confusing.

[tagilchanin]

have you tried to create a cloudinit drive in temlete?

have you tried to create a cloudinit drive in temlete?

Is that the step I'm missing from my Packer build of the template?

[tagilchanin]

I think so.

Okay, I'll give this a try over the next coming days and report back. Hopefully I can come up with a nice Packer + Terraform guide for building infra with Proxmox. Thanks! Stay turned, I'm working on it 👌

Okay your suggestion has gotten me a bit further. Here's my resulting Packer setup:

sources.hcl.pkr:

packer {
  required_plugins {
    sshkey = {
      version = ">= 0.1.0"
      source = "github.com/ivoronin/sshkey"
    }
  }
}

data "sshkey" "install" {
}

    model   = "virtio"
    bridge  = "vmbr0"
  }

  qemu_agent            = true
  scsi_controller       = "virtio-scsi-pci"

  disks {
    type              = "scsi"
    disk_size         = "30G"
    storage_pool      = var.vm_storage_pool
    storage_pool_type = "zfspool"
    format            = "raw"
  }

  ssh_username              = var.username
  ssh_private_key_file      = data.sshkey.install.private_key_path

  iso_url               = var.iso_url
  iso_storage_pool      = var.iso_storage_pool
  iso_checksum          = var.iso_checksum

  onboot                = true

  template_name         = var.vm_name
  template_description  = var.template_description
  unmount_iso           = true
  cloud_init            = true

  http_content = {
    "/cloud-config.yml" = templatefile("./templates/cloud-config.yml.pkrtpl", {
      "ssh_public_key" : data.sshkey.install.public_key
    })
  }

  boot_wait             = "10s"
  boot_command = [
    "<enter><wait2m>",
    "<enter>",
    "sudo ros install -f -c http://{{ .HTTPIP }}:{{ .HTTPPort }}/cloud-config.yml -d /dev/sda<enter>",
    "<wait2m>",
  ]
}

build {
  sources = [
    "source.proxmox-iso.template"
  ]

  provisioner "shell" {
    pause_before = "20s"
    inline = [
      # DHCP Server assigns same IP address if machine-id is preserved, new machine-id will be generated on first boot
      "sudo truncate -s 0 /etc/machine-id",
      "exit 0",
    ]
  }
}

But I've run into a problem (the above Terraform is the same) where I've been trying to figure it out here -- Burmilla OS is the Guest OS here, and It seems to only support CloudDrive v2? But Proxmox VE seems to build NoCloud v1? ISO9660 CD-ROM devices attached to the VM. I've dug into the code bases of this Terraform Provider, the Packer Proxmox plugin and even Burmilla OS and I'm at a bit of a loss as to how to solve this.

I'm open to ideas/suggestions.

[pgporada]

In your VM template/packer/whatever, what's the contents of this file:
https://pve.proxmox.com/wiki/Cloud-Init_FAQ#Creating_a_custom_cloud_image

# /etc/cloud/cloud.cfg.d/99_pve.cfg
datasource_list: [ NoCloud, ConfigDrive ]

My VM templates have ^ in a different file, but the datasource_list line appears as above.

Your terraform will need to include this. In my example general is network mounted storage on each proxmox host. I'm pretty sure this is what tells proxmox to use ConfigDrive because it will mount the network storage as an ISO9660 CD-ROM device.

  # Attaches a special cd-rom drive to each VM at /dev/sr0 for cloud-init. Cloud-init then
  # automatically mounts the drive somewhere in /run and Does The Thing.
  cloudinit_cdrom_storage = "general"

[blackliner]

So you create a single template with packer, just to clone from it with terraform 🤔 I know about #274 , just asking if I got it correctly.
