Docker Save Post-Processor

Type: docker-save

The 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

The configuration for this post-processor is extremely simple.

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

Example

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

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