:Description:   A golang multi-stage build container image example.

:Maintainer:    Jürgen Hermann 

The following commands build and run a golang binary from the source in ``hi.go``,

putting it into a from-scratch Docker image.

.. code-block:: shell

   docker build -t jhermann/gohi -t jhermann/gohi:$(git describe --tags) .

   docker run --rm -it jhermann/gohi

It doesn't get easier than this. ☺

The resulting image is only slightly larger than the contained golang binary.

.. code-block:: console

    $ dockviz images --tree jhermann/gohi

    └─927b6ad2e4fa Virtual Size: 1.4 MB Tags: jhermann/gohi:latest, jhermann/gohi:v0-1-g93bf073

To look at the image's metadata, use ``docker inspect``:

.. code-block:: shell

    docker inspect jhermann/gohi:latest | jq -CS

Leave out the ``jq`` part if you don't have that installed,

it just colorizes the output.

Using `prom/busybox:glibc` instead of `scratch` adds 6 MB in size,

a shell, and the other debugging and introspection conveniences of a full base image.
