To ease building ACRN with all its requirements, provide a distribution aware,
self-contained docker build environment to build regular Debian packages.
For Debian Buster(10) and Ubuntu Focal Fossa(20.04 LTS) some build tools are
grabbed from their respective backports repositories. This provides a much
easier alignment with the more resent distributions.
There are three packages to be re-packaged to accommodate the build needs as
well as the runtime needs of the ACRN packages:
* python3-elementpath_2.4.0-1
* python3-xmlschema_1.9.2-1
* acpica-tools_20200925-1
These packages are built during docker image build time and provided within
a local APT repository for installation at build time, i.e. when running the
respective docker container.
The multistage Dockerfile separates the required pre-build stages and reduces
the resulting image footprint of the final docker image. There are separate
docker images for each distribution.
To summarize the build steps the script acrn-docker-build.sh is provided. To
control the vendor and the distribution for the build, just set the
environment variables VENDOR and DISTRO before calling the script from the
top directory of the ACRN hypervisor workspace, e.g.:
VENDOR=debian DISTRO=bullseye debian/docker/acrn-docker-build.sh
or
VENDOR=ubuntu DISTRO=focal debian/docker/acrn-docker-build.sh
