» Proxmox Builder

Type: proxmox

The proxmox Packer builder is able to create new images for use with Proxmox. The builder takes an ISO image, runs any provisioning necessary on the image after launching it, then creates a virtual machine template. This template can then be used as to create new virtual machines within Proxmox.

The builder does not manage templates. Once it creates a template, it is up to you to use it or delete it.

» Configuration Reference

There are many configuration options available for the builder. They are segmented below into two categories: required and optional parameters. Within each category, the available configuration keys are alphabetized.

In addition to the options listed here, a communicator can be configured for this builder.

» Required:

  • proxmox_url (string) - URL to the Proxmox API, including the full path, so https://<server>:<port>/api2/json for example. Can also be set via the PROXMOX_URL environment variable.

  • username (string) - Username when authenticating to Proxmox, including the realm. For example user@pve to use the local Proxmox realm. Can also be set via the PROXMOX_USERNAME environment variable.

  • password (string) - Password for the user. Can also be set via the PROXMOX_PASSWORD environment variable.

  • node (string) - Which node in the Proxmox cluster to start the virtual machine on during creation.

  • iso_file (string) - Path to the ISO file to boot from, expressed as a proxmox datastore path, for example local:iso/Fedora-Server-dvd-x86_64-29-1.2.iso

» Optional:

  • insecure_skip_tls_verify (bool) - Skip validating the certificate.

  • pool (string) - Name of resource pool to create virtual machine in.

  • vm_name (string) - Name of the virtual machine during creation. If not given, a random uuid will be used.

  • vm_id (int) - The ID used to reference the virtual machine. This will also be the ID of the final template. If not given, the next free ID on the node will be used.

  • memory (int) - How much memory, in megabytes, to give the virtual machine. Defaults to 512.

  • cores (int) - How many CPU cores to give the virtual machine. Defaults to 1.

  • sockets (int) - How many CPU sockets to give the virtual machine. Defaults to 1

  • os (string) - The operating system. Can be wxp, w2k, w2k3, w2k8, wvista, win7, win8, win10, l24 (Linux 2.4), l26 (Linux 2.6+), solaris or other. Defaults to other.

  • network_adapters (array of objects) - Network adapters attached to the virtual machine. Example:

    [
      {
        "model": "virtio",
        "bridge": "vmbr0",
        "vlan_tag": "10"
      }
    ]
    
    • bridge (string) - Required. Which Proxmox bridge to attach the adapter to.
    • model (string) - Model of the virtual network adapter. Can be rtl8139, ne2k_pci, e1000, pcnet, virtio, ne2k_isa, i82551, i82557b, i82559er, vmxnet3, e1000-82540em, e1000-82544gc or e1000-82545em. Defaults to e1000.
    • mac_address (string) - Give the adapter a specific MAC address. If not set, defaults to a random MAC.
    • vlan_tag (string) - If the adapter should tag packets. Defaults to no tagging.
  • disks (array of objects) - Disks attached to the virtual machine. Example:

    [
      {
        "type": "scsi",
        "disk_size": "5G",
        "storage_pool": "local-lvm",
        "storage_pool_type": "lvm"
      }
    ]
    
    • storage_pool (string) - Required. Name of the Proxmox storage pool to store the virtual machine disk on. A local-lvm pool is allocated by the installer, for example.
    • storage_pool_type (string) - Required. The type of the pool, can be lvm, lvm-thin, zfspool or directory.
    • type (string) - The type of disk. Can be scsi, sata, virtio or ide. Defaults to scsi.
    • disk_size (string) - The size of the disk, including a unit suffix, such as 10G to indicate 10 gigabytes.
    • cache_mode (string) - How to cache operations to the disk. Can be none, writethrough, writeback, unsafe or directsync. Defaults to none.
    • format (string) - The format of the file backing the disk. Can be raw, cow, qcow, qed, qcow2, vmdk or cloop. Defaults to raw.
  • template_name (string) - Name of the template. Defaults to the generated name used during creation.

  • template_description (string) - Description of the template, visible in the Proxmox interface.

  • unmount_iso (bool) - If true, remove the mounted ISO from the template after finishing. Defaults to false.

  • qemu_agent (boolean) - Disables QEMU Agent option for this VM. When enabled, then qemu-guest-agent must be installed on the guest. When disabled, then ssh_host should be used. Defaults to true.

» Example: Fedora with kickstart

Here is a basic example creating a Fedora 29 server image with a Kickstart file served with Packer's HTTP server. Note that the iso file needs to be manually downloaded.
