Chef is a cross-platform package management system, specifically built to support all kinds of platforms. It's built with cross-compilation in mind and is also built to work as an application format. It's written in C to make it as portable as possible. It is relatively lightweight alternative to other package management systems, and provides an online repository for all your packages as well.
The best way to get started is to install the latest version of Chef using the snap store. However not everyone likes or uses snaps, and in this case it's recommended to build chef from source, as chef is not distributed as a debian package yet!

To get started with your account setup, you will need to activate one of the privileged commands provided by 'order'
$ order account whoami
This will initialize the account setup by asking you to login/register an account using OAUTH2 authentation methods. It will provide you with a link and a code you need to paste in to the browser.
Once authentitacted, you will be prompted to provide your publisher name (the name from which your packages will be published under), and an email used to notify you once your publisher name is approved (or rejected, in which case you may choose another).
Publishing names will be reviewed quickly (usually within 24 hours), and then you will be able to publish packages to the official Chef repository. While waiting for the approval, you can also see the current account status using
$ order account whoami
The easiest way to get started is to use the init helper provided by the command 'bake'. This will create a new .yaml recipe in the current directory, where you can customize the recipe to your liking.
$ bake init
For examples on recipes, please see the examples/ directory, the chef.yaml, or refer to the Recipe Specification in the bottom of this page.
Once the recipe is created, you can start baking!
$ bake my-recipe.yaml
This should create a new (or multiple based on your recipe) *.pack file in the current directory, which are now ready for publishing! During execution of steps, chef will expose the following variables to help control the build process:
PROJECT_PATH: path to the root of the project (where bake was invoked)INSTALL_PREFIX: path to where the steps will install files to be packedCHEF_HOST_PLATFORM: the platform for which the package is being builtCHEF_HOST_ARCHITECTURE: the architecture for which the package is being built
Chef is specifically built to work easily with cross-compilation scenarios. This allows users to build packages for other platforms or architecture and publish them as well.
$ bake my-recipe.yaml --cross-compile=linux/i386
The above will trigger chef to download ingredients for the linux/i386 platform, and then build the package for that platform. During execution of the different steps, chef will expose the following additional environment variables:
TOOLCHAIN_PREFIX: path to where the toolchain ingredient is unpackedBUILD_INGREDIENTS_PREFIX: path to where the build ingredients are unpackedCHEF_TARGET_PLATFORM: the platform which was provided on the commandlineCHEF_TARGET_ARCHITECTURE: the architecture which was provided on the commandline
Once the packages are built, they are in essence ready for publishing. To publish them, you can use the publish command:
$ order publish my-something.pack
Chef packages are designed to be installable, not just used for building. To support this the 'serve' utility is provided, and you will also need a 'served' daemon for your platform.
Currently no platforms have a served daemon implemented, however this is currently planned for linux and vali.
$ serve install publisher/package
The 'serve' utility communicates with the 'served' daemon through a network protocol, to support network control of a computer. The serve protocol provides the ability to install, update and remove packages from the system. For more information about the 'served' daemon, see the README in directory daemons/served.
