Docker Builder

Type: docker

The Docker builder builds Docker images using Docker. The builder starts a Docker container, runs provisioners within this container, then exports the container for re-use.

The Docker builder must run on a machine that supports Docker.

Basic Example

Below is a fully functioning example. It doesn't do anything useful, since no provisioners are defined, but it will effectively repackage an image.

{
  "type": "docker",
  "image": "ubuntu",
  "export_path": "image.tar"
}

Configuration Reference

All configuration options are currently required.

• export_path (string) - The path where the final container will be exported as a tar file.

• image (string) - The base image for the Docker container that will be started. This image will be pulled from the Docker registry if it doesn't already exist.
