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.

# 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
|
|
|
|
- `account_file` (string) - The JSON file containing your account
|
|
credentials. If specified, this take precedence over `googlecompute`
|
|
builder authentication method.
|
|
|
|
- `disk_size` (number) - The size of the export instances disk, this disk
|
|
is unused for the export but a larger size increase `pd-ssd` read speed.
|
|
This defaults to `200`, which is 200GB.
|
|
|
|
- `disk_type` (string) - Type of disk used to back export instance, like
|
|
`pd-ssd` or `pd-standard`. Defaults to `pd-ssd`.
|
|
|
|
- `keep_input_artifact` (boolean) - If `true`, do not delete the Google Compute
|
|
Engine (GCE) image being exported. defaults to `false`.
|
|
|
|
- `machine_type` (string) - The export instance machine type. Defaults
|
|
to `"n1-highcpu-4"`.
|
|
|
|
- `network` (string) - The Google Compute network id or URL to use for the
|
|
export instance. Defaults to `"default"`. If the value is not a URL, it
|
|
will be interpolated to
|
|
`projects/((builder_project_id))/global/networks/((network))`. This value
|
|
is not required if a `subnet` is specified.
|
|
|
|
- `subnetwork` (string) - The Google Compute subnetwork id or URL to use for
|
|
the export instance. Only required if the `network` has been created with
|
|
custom subnetting. Note, the region of the subnetwork must match the
|
|
`zone` in which the VM is launched. If the value is not a URL,
|
|
it will be interpolated to
|
|
`projects/((builder_project_id))/regions/((region))/subnetworks/((subnetwork))`
|
|
|
|
- `zone` (string) - The zone in which to launch the export instance. Defaults
|
|
to `googlecompute` builder zone. Example: `"us-central1-a"`
|
|
|
|
## 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`.
|
