There are two sets of dependencies required for the development process: build and run dependencies. We typically build, develop and test using the latest Ubuntu LTS version and run nrk in QEMU. Other Linux systems will probably work but might require a manual installation of all dependencies. Other operating systems likely won't work out of the box without some adjustments for code and the build-process.
Check out the nrk sources first:
git clone <repo-url> cd nrk
The repository is structured using git submodules. You'll have to initialize and check-out the submodules separately:
In case you don't have the SSH key of your machine registered with a github account, you need to convert all submodule URLs to use the https protocol instead of SSH, to do so run this sed script before proceeding:
sed -i'' -e 'email@example.com:/https:\/\/github.com\//' .gitmodules
git submodule update --init
If you want to build without Docker, you
can install both build and run dependencies by executing
setup.sh in the root
of the repository directly on your machine (this requires the latest Ubuntu
LTS). The script will install all required OS packages, install Rust using
rustup and some additional rust programs and
dependencies. To run rackscale integration tests, you will also have to install
the DCM-based scheduler dependencies.
The build dependencies can be divided into these categories
- Rust (nightly) and the
rust-srccomponent for compiling the OS
python3(and some python libraries) to execute the build and run script
- Test dependencies (qemu, corealloc, dhcpd, redis-benchmark, socat, graphviz etc.)
- Rumpkernel dependencies (gcc, zlib1g etc.)
- Build for documentation (mdbook)
We provide scripts to create a docker image which contains all build dependencies already.
To use Docker, it needs to be installed in your system. On Ubuntu execute the following steps:
sudo apt install docker.io sudo service docker restart sudo addgroup $USER docker newgrp docker
To create the image execute the following command in the
This will create the docker image and start the container. You will be dropped into a shell running inside the Docker container. You can build the OS as if you had installed the dependencies natively.
The script will create a user inside the docker container that corresponds to the user on the host system (same username and user ID).
You can rebuild the image with:
bash ./docker-run.sh force-build
To exit the container, just type
exit to terminate the shell.
To just build the OS invoke the
run.py script (in the kernel directory) with
-n parameter (no-run flag).
python3 kernel/run.py -n
If you want to run the build in a docker container, run
bash ./scripts/docker-run.sh beforehand. The source directory tree will be mounted
in the docker container in
