Google Compute Builder

Type: googlecompute

The googlecompute builder is able to create new images for use with Google Compute Engine.

Basic Example

Below is a fully functioning example. It doesn't do anything useful, since no provisioners are defined, but it will effectively repackage an GCE image.

{
  "type": "googlecompute",
  "bucket_name": "packer-images",
  "client_secrets_file": "client_secret_XXXXXX-XXXXXX.apps.googleusercontent.com.json",
  "private_key_file": "XXXXXX-privatekey.pem",
  "project_id": "my-project",
  "source_image": "debian-7-wheezy-v20131014",
  "zone": "us-central1-a"
}

Configuration Reference

Configuration options are organized below into two categories: required and optional. Within each category, the available options are alphabetized and described.

Required:

• bucket_name (string) - The Google Cloud Storage bucket to store images.
• client_secrets_file (string) - The client secrets file.
• private_key_file (string) - The service account private key.
• project_id (string) - The GCE project id.
• source_image (string) - The source image. Example debian-7-wheezy-v20131014.
• zone (string) - The GCE zone.

Optional:

• image_name (string) - The unique name of the resulting image. Defaults to packer-{{timestamp}}.
• image_description (string) - The description of the resulting image.
• machine_type (string) - The machine type. Defaults to n1-standard-1.
• network (string) - The Google Compute network. Defaults to default.
• passphrase (string) - The passphrase to use if the private_key_file is encrypted.
• ssh_port (int) - The SSH port. Defaults to 22.
• ssh_timeout (string) - The time to wait for SSH to become available. Defaults to 1m.
• ssh_username (string) - The SSH username. Defaults to root.
• state_timeout (string) - The time to wait for instance state changes. Defaults to 5m.

Gotchas

Centos images have root ssh access disabled by default. Set ssh_username to any user, which will be created by packer with sudo access.

The machine type must have a scratch disk, which means you can't use an f1-micro or g1-small to build images.
