»Docker Save Post-Processor

Type: docker-save

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.

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.



The configuration for this post-processor only requires one option.

  • path (string) - The path to save the image.


  • keep_input_artifact (boolean) - if true, do not delete the docker container, and only save the .tar created by docker save. Defaults to true.


An example is shown below, showing only the post-processor configuration:

  "type": "docker-save",
  "path": "foo.tar"
{  "type": "docker-save",  "path": "foo.tar"}
