Packer Build Resource for GCP based GCE

A Concourse CI resource to build new Google Compute Images (Image) via Packer

This is spawned from

• https://github.com/jdub/packer-resource
• https://github.com/rjshep/packer-resource

Source Configurations

• project (optional string): The project name the image is in (should be used when the account may not have permission to the default parent account)
• region (required string): The GCP region to work in
• credentials (required string): for GCP account
• family (optional string): used for check if you are triggering against an image family
• debug (optional string): defaults to false

Behaviour

check: Check for new versions of a GCP Image

Returns an ordered list of versions that match the criteria specified in the source. This can be used to trigger a new build when a new version of a GCE Image is created.

in: Get metadata about an GCP Image

Provides 3 files:

• version.txt - a text file containing the selected Image Name
• version.json - a JSON file containing the selected Image Name in the image field of the json parent version
• image.json - the GCE metadata for the selected Image

out: Build a new GCP Image

Parameters

• template (required string): The path to the packer template.
• var_file (optional string or list): The path or list of paths to a [external JSON variable file] (https://www.packer.io/docs/templates/user-variables.html).

All other parameters will be passed through to packer as variables.

** source.project will not be read by out process only in and check. 'project' must be passed in the packer file or packer variable.
