CloudStack Builder

Type: cloudstack

The cloudstack Packer builder is able to create new templates for use with CloudStack. The builder takes either an ISO or an existing template as it's source, runs any provisioning necessary on the instance after launching it and then creates a new template from that instance.

The builder does not manage templates. Once a template is created, 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:

api_url (string) - The CloudStack API endpoint we will connect to. It can also be specified via environment variable CLOUDSTACK_API_URL, if set.
api_key (string) - The API key used to sign all API requests. It can also be specified via environment variable CLOUDSTACK_API_KEY, if set.
network (string) - The name or ID of the network to connect the instance to.
secret_key (string) - The secret key used to sign all API requests. It can also be specified via environment variable CLOUDSTACK_SECRET_KEY, if set.
service_offering (string) - The name or ID of the service offering used for the instance.
source_iso (string) - The name or ID of an ISO that will be mounted before booting the instance. This option is mutually exclusive with source_template. When using source_iso, both disk_offering and hypervisor are required.
source_template (string) - The name or ID of the template used as base template for the instance. This option is mutually exclusive with source_iso.
template_os (string) - The name or ID of the template OS for the new template that will be created.
zone (string) - The name or ID of the zone where the instance will be created.

Optional:

async_timeout (number) - The time duration to wait for async calls to finish. Defaults to 30m.
cidr_list (array) - List of CIDR's that will have access to the new instance. This is needed in order for any provisioners to be able to connect to the instance. Defaults to [ "0.0.0.0/0" ]. Only required when use_local_ip_address is false.
create_security_group (boolean) - If true a temporary security group will be created which allows traffic towards the instance from the cidr_list. This option will be ignored if security_groups is also defined. Requires expunge set to true. Defaults to false.
disk_offering (string) - The name or ID of the disk offering used for the instance. This option is only available (and also required) when using source_iso.
disk_size (number) - The size (in GB) of the root disk of the new instance. This option is only available when using source_template.
expunge (boolean) - Set to true to expunge the instance when it is destroyed. Defaults to false.
http_directory (string) - Path to a directory to serve using an HTTP server. The files in this directory will be available over HTTP that will be requestable from the virtual machine. This is useful for hosting kickstart files and so on. By default this is "", which means no HTTP server will be started. The address and port of the HTTP server will be available as variables in user_data. This is covered in more detail below.
http_get_only (boolean) - Some cloud providers only allow HTTP GET calls to their CloudStack API. If using such a provider, you need to set this to true in order for the provider to only make GET calls and no POST calls.
http_port_min and http_port_max (number) - These are the minimum and maximum port to use for the HTTP server started to serve the http_directory. Because Packer often runs in parallel, Packer will choose a randomly available port in this range to run the HTTP server. If you want to force the HTTP server to be on one port, make this minimum and maximum port the same. By default the values are 8000 and 9000, respectively.
hypervisor (string) - The target hypervisor (e.g. XenServer, KVM) for the new template. This option is required when using source_iso.
keypair (string) - The name of the SSH key pair that will be used to access the instance. The SSH key pair is assumed to be already available within CloudStack.
instance_name (string) - The name of the instance. Defaults to "packer-UUID" where UUID is dynamically generated.
prevent_firewall_changes (boolean) - Set to true to prevent network ACLs or firewall rules creation. Defaults to false.
project (string) - The name or ID of the project to deploy the instance to.
public_ip_address (string) - The public IP address or it's ID used for connecting any provisioners to. If not provided, a temporary public IP address will be associated and released during the Packer run.
security_groups (array of strings) - A list of security group IDs or names to associate the instance with.
ssh_agent_auth (boolean) - If true, the local SSH agent will be used to authenticate connections to the source instance. No temporary keypair will be created, and the values of ssh_password and ssh_private_key_file will be ignored. To use this option with a key pair already configured in the source image, leave the keypair blank. To associate an existing key pair with the source instance, set the keypair field to the name of the key pair.
ssl_no_verify (boolean) - Set to true to skip SSL verification. Defaults to false.
template_display_text (string) - The display text of the new template. Defaults to the template_name.
template_featured (boolean) - Set to true to indicate that the template is featured. Defaults to false.
template_name (string) - The name of the new template. Defaults to "packer-{{timestamp}}" where timestamp will be the current time.
template_public (boolean) - Set to true to indicate that the template is available for all accounts. Defaults to false.
template_password_enabled (boolean) - Set to true to indicate the template should be password enabled. Defaults to false.
template_requires_hvm (boolean) - Set to true to indicate the template requires hardware-assisted virtualization. Defaults to false.
template_scalable (boolean) - Set to true to indicate that the template contains tools to support dynamic scaling of VM cpu/memory. Defaults to false.
temporary_keypair_name (string) - The name of the temporary SSH key pair to generate. By default, Packer generates a name that looks like packer_<UUID>, where <UUID> is a 36 character unique identifier.
user_data (string) - User data to launch with the instance. This is a template engine see User Data bellow for more details.
user_data_file (string) - Path to a file that will be used for the user data when launching the instance. This file will be parsed as a template engine see User Data bellow for more details.
use_local_ip_address (boolean) - Set to true to indicate that the provisioners should connect to the local IP address of the instance.

User Data

The available variables are:

HTTPIP and HTTPPort - The IP and port, respectively of an HTTP server that is started serving the directory specified by the http_directory configuration parameter. If http_directory isn't specified, these will be blank.
