Proxmox Clone
Type: proxmox-clone
Artifact BuilderId: proxmox.clone
The proxmox-clone
Packer builder is able to create new images for use with
Proxmox. The builder takes a virtual
machine template, 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.
Disks specified in a proxmox-clone
builder configuration will replace disks
that are already present on the cloned VM template. If you want to reuse the disks
of the cloned VM, don't specify disks in your configuration.
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.
You may also want to take look at the general configuration references for VirtIO RNG device and PCI Devices configuration references, which can be found further down the page.
In addition to the options listed here, a communicator can be configured for this builder.
If no communicator is defined, an SSH key is generated for use, and is used in the image's Cloud-Init settings for provisioning.
Required:
clone_vm
(string) - The name of the VM Packer should clone and build from. Eitherclone_vm
orclone_vm_id
must be specifed.clone_vm_id
(int) - The ID of the VM Packer should clone and build from. Proxmox VMIDs are limited to the range 100-999999999. Eitherclone_vm
orclone_vm_id
must be specifed.
An iso (CD) containing custom files can be made available for your build.
By default, no extra CD will be attached. All files listed in this setting get placed into the root directory of the CD and the CD is attached as the second CD device.
This config exists to work around modern operating systems that have no way to mount floppy disks, which was our previous go-to for adding files at boot time.
cd_files
([]string) - A list of files to place onto a CD that is attached when the VM is booted. This can include either files or directories; any directories will be copied onto the CD recursively, preserving directory structure hierarchy. Symlinks will have the link's target copied into the directory tree on the CD where the symlink was. File globbing is allowed.Usage example (JSON):
"cd_files": ["./somedirectory/meta-data", "./somedirectory/user-data"], "cd_label": "cidata",
Usage example (HCL):
cd_files = ["./somedirectory/meta-data", "./somedirectory/user-data"] cd_label = "cidata"
The above will create a CD with two files, user-data and meta-data in the CD root. This specific example is how you would create a CD that can be used for an Ubuntu 20.04 autoinstall.
Since globbing is also supported,
cd_files = ["./somedirectory/*"] cd_label = "cidata"
Would also be an acceptable way to define the above cd. The difference between providing the directory with or without the glob is whether the directory itself or its contents will be at the CD root.
Use of this option assumes that you have a command line tool installed that can handle the iso creation. Packer will use one of the following tools:
- xorriso
- mkisofs
- hdiutil (normally found in macOS)
- oscdimg (normally found in Windows as part of the Windows ADK)
cd_content
(map[string]string) - Key/Values to add to the CD. The keys represent the paths, and the values contents. It can be used alongsidecd_files
, which is useful to add large files without loading them into memory. If any paths are specified by both, the contents incd_content
will take precedence.Usage example (HCL):
cd_files = ["vendor-data"] cd_content = { "meta-data" = jsonencode(local.instance_data) "user-data" = templatefile("user-data", { packages = ["nginx"] }) } cd_label = "cidata"

environment variable.password

takes precedence.node

CloudInit Ip Configuration
If you have configured more than one network interface, make sure to match the order of
network_adapters
and ipconfig
.
Usage example (JSON):
[
{
"ip": "192.168.1.55/24",
"gateway": "192.168.1.1",
"ip6": "fda8:a260:6eda:20::4da/128",

Additional ISO Files
additional_iso_files
(array of objects) - Additional ISO files attached to the virtual machine. Example:[ { "device": "scsi5", "iso_file": "local:iso/virtio-win-0.1.185.iso", "unmount": true, "iso_checksum": "af2b3cc9fa7905dea5e58d31508d75bba717c2b0d5553962658a47aebc9cc386" } ]
By default, Packer will symlink, download or copy image files to the Packer
cache into a "hash($iso_url+$iso_checksum).$iso_target_extension
" file.
Packer uses hashicorp/go-getter in
file mode in order to perform a download.
go-getter supports the following protocols:
- Local files
- Git
- Mercurial
- HTTP
- Amazon S3
Examples:
go-getter can guess the checksum type based on iso_checksum
length, and it is
also possible to specify the checksum type.
In JSON:
"iso_checksum": "946a6077af6f5f95a51f82fdc44051c7aa19f9cfc5f737954845a6050543d7c2",

Required
iso_checksum
(string) - The checksum for the ISO file or virtual hard drive file. The type of the checksum is specified within the checksum field as a prefix, ex: "md5:{$checksum}". The type of the checksum can also be omitted and Packer will try to infer it based on string length. Valid values are "none", "{$checksum}", "md5:{$checksum}", "sha1:{$checksum}", "sha256:{$checksum}", "sha512:{$checksum}" or "file:{$path}". Here is a list of valid checksum values:- md5:090992ba9fd140077b0661cb75f7ce13
- 090992ba9fd140077b0661cb75f7ce13

- file:http://releases.ubuntu.com/20.04/SHA256SUMS
- file:file://./local/path/file.sum

oriso_urls
can be specified.iso_target_path
(string) - The path where the iso should be saved after download. By default will go in the packer cache, with a hash of the original filename and checksum as its name.iso_target_extension

cd_label
(string) - CD Label
EFI Config

VirtIO RNG device
rng0
(object): Configure Random Number Generator via VirtIO. A virtual hardware-RNG can be used to provide entropy from the host system to a guest VM helping avoid entropy starvation which might cause the guest system slow down. The device is sourced from a host device and guest, his use can be limited:max_bytes
bytes of data will become available on aperiod
ms timer. PVE documentation recommends to always use a limiter to avoid guests using too many host resources.
HCL2 example:
rng0 {
source = "/dev/urandom"
max_bytes = 1024
period = 1000
}
JSON example:
{
"rng0": {
"source": "/dev/urandom",
"max_bytes": 1024,
"period": 1000
}
}
Required:
source
(string) - Device on the host to gather entropy from./dev/urandom
should be preferred over/dev/random
as Proxmox PVE documentation suggests./dev/hwrng
can be used to pass through a hardware RNG. Can be one of/dev/urandom
,/dev/random
,/dev/hwrng
.max_bytes
(int) - Maximum bytes of entropy allowed to get injected into the guest everyperiod
milliseconds. Use a lower value when using/dev/random
since can lead to entropy starvation on the host system.0
disables limiting and according to PVE documentation is potentially dangerous for the host. Recommended value:1024
.
Optional:
period
(int) - Period in milliseconds on which the the entropy-injection quota is reset. Can be a positive value. Recommended value:1000
.
PCI devices
Allows passing through a host PCI device into the VM. For example, a graphics card
or a network adapter. Devices that are mapped into a guest VM are no longer available
on the host. A minimal configuration only requires either the host
or the mapping
key to be specifed.
Note: VMs with passed-through devices cannot be migrated.
HCL2 example:
pci_devices {
host = "0000:0d:00.1"
pcie = false
device_id = "1003"
legacy_igd = false
mdev = "some-model"
hide_rombar = false
