Onedir Packaging
================

Relenv onedir packaging
=======================

Starting in 3006, only onedir packaging will be available. The 3006 onedir packages
are built with the `relenv <https://github.com/saltstack/relative-environment-for-python>`_ tool.


Docker Containers
=================
The Salt Project uses docker containers to build our packages. If you are building your own packages you can use
the same containers we build with in the Github piplines. These containers are documented `here <https://github.com/saltstack/salt-ci-containers/tree/main/custom/packaging>`_.


How to build onedir only
========================

#. Install relenv:

    .. code-block:: bash

       pip install relenv

#. Fetch toolchain (Only required for linux OSs)

    .. code-block:: bash

       relenv toolchain fetch

#. Fetch Native Python Build:

    .. code-block:: bash

       relenv fetch --python=<python-version>

#. Create relenv environment:

    .. code-block:: bash

       relenv create --python=<python-version> <relenv-package-path>

#. Add Salt into onedir.

    .. code-block:: bash

       <relenv-package-path>/bin/pip install /path/to/salt


How to build rpm packages
=========================
#. Install the dependencies:

    .. code-block:: bash

       yum -y install python3 python3-pip openssl git rpmdevtools rpmlint systemd-units libxcrypt-compat git gnupg2 jq createrepo rpm-sign rustc cargo epel-release
       yum -y install patchelf
       pip install awscli

    .. code-block:: bash

       pip install -r requirements/static/ci/py{python_version}/tools.txt

#. (Optional) To build a specific Salt version, you will need to install tools and changelog dependencies:


    .. code-block:: bash

       pip install -r requirements/static/ci/py{python_version}/changelog.txt

#. Ensure you are in the current Salt cloned git repo:

    .. code-block:: bash

       cd <path-to-salt-repo>

#. (Optional) To build a specific Salt version, run tools and set Salt version:

    .. code-block:: bash

       tools changelog update-rpm <salt-version>

#. Build the RPM:

    Only the arch argument is required, the rest are optional.

    .. code-block:: bash

       tools pkg build rpm --relenv-version <relenv-version> --python-version <python-version> --arch <arch>



How to build deb packages
=========================

#. Install the dependencies:

    .. code-block:: bash

       apt install -y apt-utils gnupg jq awscli python3 python3-venv python3-pip build-essential devscripts debhelper bash-completion git patchelf rustc

    .. code-block:: bash

       pip install -r requirements/static/ci/py{python_version}/tools.txt

#. (Optional) To build a specific Salt version, you will need to install changelog dependencies:

    .. code-block:: bash

       pip install -r requirements/static/ci/py{python_version}/changelog.txt

#. Ensure you are in the current Salt cloned git repo.:

    .. code-block:: bash

       cd <path-to-salt-repo>

#. (Optional) To build a specific Salt version, run tools and set Salt version:

    .. code-block:: bash

       tools changelog update-deb <salt-version>


#. Build the deb package:

    Only the arch argument is required, the rest are optional.

    .. code-block:: bash

       tools pkg build deb --relenv-version <relenv-version> --python-version <python-version> --arch <arch>


How to access python binary
===========================

The python library is available in the install directory of the onedir package. For example
on linux the default location would be ``/opt/saltstack/salt/bin/python3``.
