Following is the instruction on how to build an [(ONIE)](https://github.com/opencomputeproject/onie) compatiable network operating system (NOS) installer image for network switches, and also how to build docker images running inside the NOS. Note that SONiC image are build per ASIC platform. Switches using the same ASIC platform share a common image. For a list of supported switches and ASIC, please refer to this [document](https://sonic-jenkins.westus.cloudapp.azure.com/job/p4/job/buildimage-p4-all).
NOTE: If the repo has already been cloned, however there are no files under the submodule directories (e.g., src/lldpd, src/ptf, src/sonic-linux-kernel, etc.), you can manually fetch all the git submodules as follows:
You may find the rules/config file useful. It contains configuration options for the build process, like adding more verbosity or showing dependencies, username and password for base image etc.
It is recommended to use clean targets to clean all packages that are built together, like dev packages for instance. In order to be more familiar with build process and make some changes to it, it is recommended to read this short [Documentation](README.buildsystem.md).
We're following basic GitHub Flow. If you have no idea what we're talking about, check out [GitHub's official guide](https://guides.github.com/introduction/flow/). Note that merge is only performed by the repository maintainer.
Guide for performing commits:
* Isolate each commit to one component/bugfix/issue/feature
* Use a standard commit message format:
> [component/folder touched]: Description intent of your changes
>
> [List of changes]
>
> Signed-off-by: Your Name your@email.com
For example:
> swss-common: Stabilize the ConsumerTable
>
> * Fixing autoreconf
> * Fixing unit-tests by adding checkers and initialize the DB before start
> * Adding the ability to select from multiple channels
> * Health-Monitor - The idea of the patch is that if something went wrong with the notification channel,
> we will have the option to know about it (Query the LLEN table length).
>
> Signed-off-by: user@dev.null
