Docker Save

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.

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.

Example

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

JSON

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

post-processor "docker-save" {  path = "foo.tar"}
