intel-iot-refkit

This README file contains information on setting up, building, and booting Iot Reference OS Kit for Intel(r) Architecture project.

Installing Docker on Linux

You’ll need Docker installed to build locally. Using Docker provides a packaged and controlled environment for building an image, eliminating development environment issues that can occur with differing Linux OS distros and versions, different host compilers, and such. (There are instructions later below for building without Docker.)

Instructions for installing Docker for common Linux distros on your development machine (including Fedora and Ubuntu) are available at: https://docs.docker.com/engine/installation/linux

Follow the instructions for your particular distro. You should also perform some of listed Optional Docker Configuration settings:

• Add your Linux user account into the Docker system group with:

  $ sudo gpasswd -a ${USER} docker
  

  You’ll need to log out and back in for this change to take effect.

• Inside company firewalls, you’ll need to configure proxies. Follow the instructions for Docker at https://docs.docker.com/engine/admin/systemd/#http-proxy and also set the usual environment variables:

  $ export http_proxy=http://proxy.example.com:<port>
  $ export https_proxy=https://proxy.example.com:<port>
  $ export ALL_PROXY=socks://proxy.example.com:<port>
  

• Some distributions such as Ubuntu require you to manually configure the DNS server for Docker. This can be done by adding --dns <dns-server-ip-address> to the Docker daemon startup parameters in /etc/default/docker. (Check your /etc/resolv.conf file for system’s specific DNS settings.) More information is available here (note that Ubuntu 15.10 and later use systemd):

  • https://docs.docker.com/engine/admin/configuring/
  • https://docs.docker.com/engine/userguide/networking/configure-dns/

Building with Docker

These instructions assume you’ll be working with the sources in a ~/work/intel-iot-refkit directory that you’ll be creating.

Start by cloning the GitHub repos. If you have a previous copy of this repository without all the submodules, it would be best to remove all the content of workspace directory and clone it again:

$ export WORKSPACE=$HOME/work/intel-iot-refkit
$ mkdir -p $HOME/work
$ cd $HOME/work
$ git clone --recursive https://github.com/intel/intel-iot-refkit.git
$ cd $WORKSPACE

When Docker is configured properly and all project code is cloned and available locally, it's time to trigger a build. To do this run the command from within the ~/work/intel-iot-refkit directory:

$ docker/local-build.sh

Building without Docker

While not recommended, you can also use Yocto Project bitbake directly. (Any issues you encounter building this way might not be easily reproducible and debuggable by other developers using a different distribution.)

Here are the basic steps, preparation:

$ mkdir -p $HOME/work
$ cd $HOME/work
$ git clone --recursive https://github.com/intel/intel-iot-refkit.git
$ cd intel-iot-refkit
$ source refkit-init-build-env

Edit :file:`conf/local.conf` to select whether to build the production or the development image. More details about the choices in that file.

Basic steps, build:

$ bitbake refkit-image-common

Updating Repositories

You may need to pull new content from the GitHub repo as it’s updated. Use the following commands:

$ git pull
$ git submodule update

For more information about Git submodule commands, check this link: https://git-scm.com/docs/git-submodule
