The Google Compute Image Exporter post-processor exports an image from a Packer googlecompute builder run and uploads it to Google Cloud Storage. The exported images can be easily shared and uploaded to other Google Cloud Projects.	docs	Google Compute Image Exporter - Post-Processors	docs-post-processors-googlecompute-export

Google Compute Image Exporter Post-Processor

Type: googlecompute-export

The Google Compute Image Exporter post-processor exports the resultant image from a googlecompute build as a gzipped tarball to Google Cloud Storage (GCS).

The exporter uses the same Google Cloud Platform (GCP) project and authentication credentials as the googlecompute build that produced the image. A temporary VM is started in the GCP project using these credentials. The VM mounts the built image as a disk then dumps, compresses, and tars the image. The VM then uploads the tarball to the provided GCS paths using the same credentials.

As such, the authentication credentials that built the image must have write permissions to the GCS paths.

Configuration

Required

paths (list of string) - The list of GCS paths, e.g. 'gs://mybucket/path/to/file.tar.gz', where the image will be exported.

Optional

keep_input_artifact (boolean) - If true, do not delete the Google Compute Engine (GCE) image being exported.

Basic Example

The following example builds a GCE image in the project, my-project, with an account whose keyfile is account.json. After the image build, a temporary VM will be created to export the image as a gzipped tarball to gs://mybucket1/path/to/file1.tar.gz and gs://mybucket2/path/to/file2.tar.gz. keep_input_artifact is true, so the GCE image won't be deleted after the export.

In order for this example to work, the account associated with account.json must have write access to both gs://mybucket1/path/to/file1.tar.gz and gs://mybucket2/path/to/file2.tar.gz.
