Build containers for Project ACRN

Introduction

This folder contains a number of Dockerfile that include all the build tools and dependencies to build the ACRN Project components, i.e. the hypervisor, devicemodel and tools

The workflow is pretty simple and can be summarized in these few steps:

Build the build containers based on your preferred OS
Clone the Project ACRN repository
Start the build container and give it the repository
Build the Project ACRN components

The pre-requisite is that you have Docker installed on your machine. Explaining how to install it on your system is beyond the scope of this document, please visit https://www.docker.com for detailed instructions.

Build the build containers

Each Dockerfile in this repo has an extension that tells what Linux distribution it is based on. To build a container using any of those, use this command:

$ sudo docker build -t <container-name> -f Dockerfile.<baseos> .

As an example, to build a container based on CentOS 7, do:

$ sudo docker build -t centos7 -f Dockerfile.centos7 .

Clone Project ACRN

Follow these simple steps to clone the Project ACRN repositories

$ mkdir ~/acrn
$ cd ~/acrn
$ git clone https://github.com/projectacrn/acrn-hypervisor

Start the build container

Use this ~/acrn/acrn-hypervisor folder and pass it on to your build container:

$ cd ~/acrn/acrn-hypervisor
$ sudo docker run -ti -v $PWD:/root/acrn <container-name>

Using CentOS 7 again as an example, that gives us:

$ cd ~/acrn/acrn-hypervisor
$ sudo docker run -ti -v $PWD:/root/acrn centos7

Note: if you encounter permission issues within the container (as it happens on a Fedora 27 host), try adding the :z parameter to the mount option. This will unlock the permission restriction (that comes from SElinux). Your command-line would then be:

$ cd ~/acrn/acrn-hypervisor
$ sudo docker run -ti -v $PWD:/root/acrn:z centos7

Build the ACRN components

The steps above place you inside the container and give you access to the Project ACRN repository you cloned earlier. You can now build any of the components. Here are a few examples:

# make hypervisor PLATFORM=uefi
# make devicemodel
# make tools

If you want to build it all, simply do:

# make PLATFORM=uefi

You can do this for all build combinations. All the build dependencies and tools are pre-installed in the container as well as a couple of useful tools (git and vim) so you can directly edit files to experiment from within the container.

The tools to build the ACRN documentation is (still) missing from these containers.
