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`
|
|
|
|
The Packer Docker Save post-processor takes an artifact from the [docker
|
|
builder](/docs/builders/docker.html) 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
|
|
|
|
The configuration for this post-processor only requires one option.
|
|
|
|
- `path` (string) - The path to save the image.
|
|
|
|
## Example
|
|
|
|
An example is shown below, showing only the post-processor configuration:
|
|
|
|
``` json
|
|
{
|
|
"type": "docker-save",
|
|
"path": "foo.tar"
|
|
}
|
|
```
