`packer <https://www.packer.io/>`_ is used to generate the base images for the cluster.

Build scripts
|
|
|
|
|
-------------
|
|
|
|
|
|
|
|
|
|
There are a few scripts that are used in building a packer image. In general,
|
|
|
|
|
the workflow looks like:
|
|
|
|
|
|
|
|
|
|
1. ``install-packer.sh``
|
|
|
|
|
2. ``build-image.sh``
|
|
|
|
|
|
|
|
|
|
``install-packer.sh``
|
|
|
|
|
^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
|
|
|
|
|
|
``install-packer.sh`` will install ``packer`` and ``packer-builder-arm``. If
|
|
|
|
|
``git`` isn't installed, it will assume that it should install dependencies. It
|
|
|
|
|
will attempt to install these dependencies with ``apt``.
|
|
|
|
|
|
|
|
|
|
The script will clone the ``packer-builder-arm`` into the ``build`` directory.
|
|
|
|
|
|
|
|
|
|
The dependencies required to build images with ``packer`` are:
|
|
|
|
|
|
|
|
|
|
- git
|
|
|
|
|
- unzip
|
|
|
|
|
- xz-utils
|
|
|
|
|
- qemu-user-static
|
|
|
|
|
- e2fsprogs
|
|
|
|
|
- dosfstools
|
|
|
|
|
- libarchive-tools
|
|
|
|
|
|
|
|
|
|
Go will also need to be installed; there is a script provided in the :doc:`tools`
|
|
|
|
|
directory.
