NAME

gcp-hashicorp-packer-updater(1) -- update google source image versions in Packer templates

SYNOPSIS

gcp-hashicorp-packer-updater 
   [-configuration name | -use-default-credentials] 
   [-project project] 
   [-filename path]

DESCRIPTION

Updates the Google source image version in your packer template to the latest version.

If the packer template contains one or more builders of type googlecompute it will query the Google Compute Engine API to determine the latest version of the specified source image.

If the source_image_project_id is not specified, it to derive this from the family or image name. If none is found the currently configured project or specified project will be used.

The utility assumes that the source_image follows the name pattern .*-v.*.

When a match is found, the utility will set or update the following fields:

• source_image
• source_image_family
• source_image_project_id
