b/ci: update build container to Fedora 35

Fedora 32 is EOL since over half a year, update to the current stable
Fedora release.

toolchains: adds clang as it's no longer part of the llvm package,
changes toolchain path references to GCC 11, and rebuilds the sysroot.

edk2: update to latest stable (old version cannot build with a newer
minor version of Python 3) and patch to disable -Werror and make the
newer included Brotli version work as it natively includes BUILD
files which need to be patched out to make the source files accessible.

linux: add patch to fix PVH ELF note entrypoint with binutils 2.32+ as
otherwise the .notes section gets emitted with broken alignment.

m/t/launch: RunMicroVM is broken if SerialPort is not set with newer
QEMU versions because fcntl(2) fails to interact with a broken file
descriptor. This is due to a confusion between nil interfaces and
interfaces containing a nil pointer causing Go to improperly pass the
file descriptor. Changing the type of SerialPort to the actual
interface resolves the issue.

Monogon Monorepo

This is the main repository containing the source code for the Monogon Project.

This is pre-release software - feel free to look around, and check back later for our first release!

Environment

Our build environment requires a working Podman binary (your distribution should have one).

Usage

Spinning up: scripts/create_container.sh

Spinning down: scripts/destroy_container.sh

Running commands: scripts/run_in_container.sh <...>

Using bazel using a wrapper script: scripts/bin/bazel <...> (add to your local $PATH for convenience)

IntelliJ

This repository is compatible with the IntelliJ Bazel plugin, which enables full autocompletion for external dependencies and generated code. All commands run inside the container, and necessary paths are mapped into the container.

The following steps are necessary:

  • Install Google's Bazel plugin in IntelliJ. On IntelliJ 2020.3 or later, you need to install a beta release of the plugin.

  • Add the absolute path to your ~/.cache/bazel-monogon folder to your idea64.vmoptions (Help → Edit Custom VM Options) and restart IntelliJ:

    -Dbazel.bep.path=/home/leopold/.cache/bazel-monogon

  • Set "Bazel Binary Location" in Other Settings → Bazel Settings to the absolute path of scripts/bin/bazel. This is a wrapper that will execute Bazel inside the container.

  • Use File → Import Bazel project... to create a new project from .bazelproject.

After running the first sync, everything should now resolve in the IDE, including generated code.

Metropolis

Run a single node cluster

Launch the node:

scripts/bin/bazel run //:launch

Run a kubectl command:

scripts/bin/bazel run //metropolis/cli/dbg -- kubectl describe

Run tests:

scripts/bin/bazel test //...
