The Packer Docker Save post-processor takes an artifact from the docker
|
|
builder
|
|
|
|
that was committed and saves it to a file. This is similar to exporting the
|
|
|
|
Docker image directly from the builder, except that it preserves the hierarchy
|
|
|
|
of images and metadata.

# Docker Save Post-Processor
|
|
|
|
Type: `docker-save`
|
|
Artifact BuilderId: `packer.post-processor.docker-save`
|
|
|
|
The Packer Docker Save post-processor takes an artifact from the [docker
|
|
builder](/docs/builders/docker) that was committed and saves it to a file.
|
|
This is similar to exporting the Docker image directly from the builder, except
|
|
that it preserves the hierarchy of images and metadata.
|
|
|
|
We understand the terminology can be a bit confusing, but we've adopted the
|
|
terminology from Docker, so if you're familiar with that, then you'll be
|
|
familiar with this and vice versa.
|
|
|
|
## Configuration
|
|
|
|
### Required
|
|
|
|
The configuration for this post-processor only requires one option.
|
|
|
|
- `path` (string) - The path to save the image.
|
|
|
|
### Optional
|
|
|
|
- `keep_input_artifact` (boolean) - if true, do not delete the docker
|
|
container, and only save the .tar created by docker save. Defaults to true.
|
|
|
|
