Unikraft Application Tests

Add tests of various applications and libraries running on top of Unikraft.

Use an Application Test

Enter the application directory and then run the scripts/setup.sh script. For example, for C helloworld, run the commands:

cd lang/c/helloworld/
../../../scripts/setup.sh

The setup script clones required repositories and generates the Makefile file.

Configure the application:

make menuconfig

Build the application:

make prepare
make -j $(nproc)

Run the application using the corresponding command, depending on your hypervisor and VMM (i.e. qemu-system-x86_64, firecracker).

Add a New Application Test

New application tests will get their own directories, similar to the helloworld C or helloworld C++ applications.

Steps to be done are:

  1. Create the new application directory.

  2. Inside the new application directory, add source code files and the Makefile.uk file that uses the source code files for the build.

  3. Fill the libs.txt with the depending Unikraft libraries. Add one library per-line, without the lib- prefix for the repository name. That is, for the lib-libcxx repository, add libcxx; for the lib-musl repository add musl; for the lib-openssl repository add openssl.

This is it, you can now commit your changes to the app-testing repository.

Now, to test it, follow the steps also mentioned above:

  1. Inside the app directory, run the scripts/setup.sh script. Be sure to provide the proper path to the script; depending on your app directory, this may be something like ../../../scripts/setup.sh or ../../scripts/setup.sh or ../scripts/setup.sh.

    The scripts/setup.sh script will create the workdir/ directory with all the repository clones (the unikraft repository and required library repositories). It will also create the Makefile file used for configuring and building the application.

  2. Configure the application with make menuconfig.

  3. Build the application with make prepare and make -j $(nproc).

  4. Run the application with the corresponding run command.
