UpCloud

Type: upcloud

The upcloud builder is used to generate storage templates on UpCloud.

Required

username (string) - The username to use when interfacing with the UpCloud API.
password (string) - The password to use when interfacing with the UpCloud API.
zone (string) - The zone in which the server and template should be created (e.g. nl-ams1).
storage_uuid (string) - The UUID of the storage you want to use as a template when creating the server.
Optionally use storage_name parameter to find matching storage

Optional

storage_name (string) - The name of the storage that will be used to find the first matching storage in the list of existing templates.
Note that storage_uuid parameter has higher priority. You should use either storage_uuid or storage_name for not strict matching (e.g "ubuntu server 20.04").
template_prefix (string) - The prefix to use for the generated template title. Defaults to custom-image. You can use this option to easily differentiate between different templates.
template_name (string) - Similarly to template_prefix, but this will allow you to set the full template name and not just the prefix. Defaults to an empty string, meaning the name will be the storage title. You can use this option to easily differentiate between different templates. It cannot be used in conjunction with the prefix setting.
storage_size (int) - The storage size in gigabytes. Defaults to 25. Changing this value is useful if you aim to build a template for larger server configurations where the preconfigured server disk is larger than 25 GB. The operating system disk can also be later extended if needed. Note that Windows templates require large storage size, than default 25 Gb.
state_timeout_duration (duration string | ex: "1h5m2s") - The amount of time to wait for resource state changes. Defaults to 5m.
boot_wait (duration string | ex: "1h5m2s") - The amount of time to wait after booting the server. Defaults to '0s'
clone_zones ([]string) - The array of extra zones (locations) where created templates should be cloned. Note that default state_timeout_duration is not enough for cloning, better to increase a value depending on storage size.
network_interfaces ([]NetworkInterface) - The array of network interfaces to request during the creation of the server for building the packer image.
ssh_private_key_path (string) - Path to SSH Private Key that will be used for provisioning and stored in the template.
ssh_public_key_path (string) - Path to SSH Public Key that will be used for provisioning.

Network Interfaces object (NetworkInterface)

ip_addresses ([]IPAddress) - List of IP Addresses
type (InterfaceType) - Network type (e.g. public, utility, private)
network (string) - Network UUID when connecting private network

IP Address object (IPAddress)

default (bool) - Default IP address. When set to true SSH communicator will connect to this IP after boot.
family (string) - IP address family (IPv4 or IPv6)
address (string) - IP address. Note that at the moment using floating IPs is not supported.

Example Usage

Here is a sample template, which you can also find in the example directory. It reads your UpCloud API credentials from the environment variables, creates an Ubuntu 20.04 LTS server in the nl-ams1 region and authorizes root user to loggin with your public SSH key.

packer {
  required_plugins {
    upcloud = {
      version = ">=v1.0.0"
      source  = "github.com/UpCloudLtd/upcloud"
    }
  }
}

variable "username" {
  type        = string
  description = "UpCloud API username"
  default     = "${env("UPCLOUD_USERNAME")}"
}

variable "password" {
  type        = string
  description = "UpCloud API password"
  default     = "${env("UPCLOUD_PASSWORD")}"
  sensitive   = true
}

variable "ssh_public_key" {
  type        = string
  description = "Path to your SSH public key file"
  default     = "~/.ssh/id_rsa.pub"
}

source "upcloud" "test" {
  username        = "${var.username}"
  password        = "${var.password}"
  zone            = "nl-ams1"
  storage_name    = "ubuntu server 20.04"
  template_prefix = "ubuntu-server"
}

build {
  sources = ["source.upcloud.test"]

  provisioner "shell" {
    inline = [
      "apt-get update",
      "apt-get upgrade -y",
      "echo '${file(var.ssh_public_key)}' | tee /root/.ssh/authorized_keys"
    ]
  }
}

Configuration reads your SSH public key from the default location ~/.ssh/id_rsa.pub. You can overwrite variables using command line argumen -var:

$ packer build -var="ssh_public_key=/some/other/path/id_rsa.pub"

Network interfaces

This template uses network_interfaces to define network interfaces to be used during the creation of the server for building the packer image.

packer {
  required_plugins {
    upcloud = {
      version = ">=v1.0.0"
      source  = "github.com/UpCloudLtd/upcloud"
    }
  }
}

variable "username" {
  type        = string
  description = "UpCloud API username"
  default     = "${env("UPCLOUD_USERNAME")}"
}

variable "password" {
  type        = string
  description = "UpCloud API password"
  default     = "${env("UPCLOUD_PASSWORD")}"
  sensitive   = true
}

variable "ssh_public_key" {
  type        = string
  description = "Path to your SSH public key file"
  default     = "~/.ssh/id_rsa.pub"
}

source "upcloud" "test" {
  username        = "${var.username}"
  password        = "${var.password}"
  zone            = "nl-ams1"
  storage_name    = "ubuntu server 20.04"
  template_prefix = "ubuntu-server"

  network_interfaces {
    ip_addresses {
      family = "IPv4"
    }
    type = "public"
  }

  network_interfaces {
    ip_addresses {
      family = "IPv4"
    }
    type = "utility"
  }
