HyperOne Builder

Type: hyperone

The hyperone Packer builder is able to create new images on the HyperOne platform. The builder takes a source image, runs any provisioning necessary on the image after launching it, then creates a reusable image.

The builder does not manage images. Once it creates an image, it is up to you to use it or delete it.

Authentication

HyperOne supports several authentication methods, which are all supported by this builder.

User session

If using user session, set the token field to your authentication token. The project field is required when using this method.

{
    "token": "YOUR TOKEN",
    "project": "YOUR_PROJECT"
}

User session by SSH key

If you've added an SSH key as a credential to your user account and the private key is added to the ssh-agent on your local machine, you can authenticate by setting just the platform login (your e-mail address):

{
    "token_login": "your.user@example.com"
}

h1 CLI

If you're using h1-cli on your local machine, HyperOne builder can use your credentials saved in a config file.

All you have to do is login within the tool:

h1 login --username your.user@example.com 

You don't have to set token or project fields at all using this method.

Service account

Using h1, you can create a new token associated with chosen project.

h1 project token add --name packer-builder --project PROJECT_ID

Set the token field to the generated token or save it in the HYPERONE_TOKEN environment variable. You don't have to set the project option using this method.

{
    "token": "YOUR TOKEN"
}

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:

• disk_size (float) - Size of the created disk, in GiB.

• project (string) - The id or name of the project. This field is required only if using session tokens. It should be skipped when using service account authentication.

• source_image (string) - ID or name of the image to launch server from.

• token (string) - The authentication token used to access your account. This can be either a session token or a service account token. If not defined, the builder will attempt to find it in the following order:

  • In HYPERONE_TOKEN environment variable.
  • In ~/.h1-cli/conf.json config file used by h1-cli.
  • By using SSH authentication if token_login variable has been set.

• vm_type (string) - ID or name of the type this server should be created with.

Optional:

• api_url (string) - Custom API endpoint URL, compatible with HyperOne. It can also be specified via environment variable HYPERONE_API_URL.

• disk_name (string) - The name of the created disk.

• disk_type (string) - The type of the created disk. Defaults to ssd.

• image_description (string) - The description of the resulting image.

• image_name (string) - The name of the resulting image. Defaults to "packer-{{timestamp}}" (see configuration templates for more info).

• image_service (string) - The service of the resulting image.

• image_tags (map of key/value strings) - Key/value pair tags to add to the created image.

• network (string) - The ID of the network to attach to the created server.

• private_ip (string) - The ID of the private IP within chosen network that should be assigned to the created server.

• public_ip (string) - The ID of the public IP that should be assigned to the created server. If network is chosen, the public IP will be associated with server's private IP.

• public_netadp_service (string) - Custom service of public network adapter. Can be useful when using custom api_url. Defaults to public.

• ssh_keys (array of strings) - List of SSH keys by name or id to be added to the server on launch.

• state_timeout (string) - Timeout for waiting on the API to complete a request. Defaults to 5m.

• token_login (string) - Login (an e-mail) on HyperOne platform. Set this if you want to fetch the token by SSH authentication.

• user_data (string) - User data to launch with the server. Packer will not automatically wait for a user script to finish before shutting down the instance, this must be handled in a provisioner.

• vm_name (string) - The name of the created server.

• vm_tags (map of key/value strings) - Key/value pair tags to add to the created server.

Chroot disk

Required:

• chroot_disk (bool) - Set to true to enable chroot disk build.

• pre_mount_commands (array of strings) - A series of commands to execute before mounting the chroot. This should include any partitioning and filesystem creation commands. The path to the device is provided by {{.Device}}.

Optional:

• chroot_command_wrapper (string) - How to run shell commands. This defaults to {{.Command}}. This may be useful to set if you want to set environment variables or run commands with sudo.

• chroot_copy_files (array of strings) - Paths to files on the running VM that will be copied into the chroot environment before provisioning. Defaults to /etc/resolv.conf so that DNS lookups work.

• chroot_disk_size (float) - The size of the chroot disk in GiB. Defaults to disk_size.

• chroot_disk_type (string) - The type of the chroot disk. Defaults to disk_type.

• chroot_mount_path (string) - The path on which the device will be mounted.

• chroot_mounts (array of strings) - A list of devices to mount into the chroot environment. This is a list of 3-element tuples, in order:

  • The filesystem type. If this is "bind", then Packer will properly bind the filesystem to another mount point.

  • The source device.

  • The mount directory.

• mount_options (array of tuples) - Options to supply the mount command when mounting devices. Each option will be prefixed with -o and supplied to the mount command.

• mount_partition (string) - The partition number containing the / partition. By default this is the first partition of the volume (for example, sdb1).

• post_mount_commands (array of strings) - As pre_mount_commands, but the commands are executed after mounting the root device and before the extra mount and copy steps. The device and mount path are provided by {{.Device}} and {{.MountPath}}.

Basic Example

Here is a basic example. It is completely valid as soon as you enter your own token.

{
    "type": "hyperone",
    "token": "YOUR_AUTH_TOKEN",
    "source_image": "ubuntu-18.04",
    "vm_type": "a1.nano",
    "disk_size": 10
}

Chroot Example

{
    "type": "hyperone",
    "token": "YOUR_AUTH_TOKEN",
    "source_image": "ubuntu-18.04",
    "vm_type": "a1.nano",
    "disk_size": 10,
    "chroot_disk": true,
    "pre_mount_commands": [
        "apt-get update",
        "apt-get install debootstrap",
        "debootstrap --arch amd64 bionic {{.MountPath}}"
    ]
}
