# tarpoon

Docker Build -- Without the Docker

Tarpoon starts with a base image, appends an application's tarball, and pushes the resulting image to a Docker registry. It replaces the need for Docker in Docker or Docker on Docker hackery.

## Build

Install packages for dynamic dependencies.

    sudo dnf install gpgme-devel
    sudo dnf install libassuan-devel

Build using Go 1.7 or higher.

    go build -o tarpoon git.barakmich.com/barak/tarpoon

## Examples

Create an example app tarball.

    echo "hello" > examples/world

Tar the application.

    tar czf world.tar examples/world

Build and push the image.

    ./tarpoon -b //busybox world.tar //docker.io/username/test-image

Verify the Docker image works contains the contents.

    sudo docker run username/test-image
