third_party/chrony: initialize

First pass at building chrony. Minimal functionality, notably skipped
features are:

 - PRIVDROP (requires libcap)
 - NTS (requires gnutls)

Do we need anything else?

Tested with:

    $ bazel build '@chrony//:chrony' --crosstool_top=//build/toolchain/musl-host-gcc:musl_host_cc_suite
    $ file bazel-bin/external/chrony/chrony
    bazel-bin/external/chrony/chrony: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, not stripped
    $ bazel-bin/external/chrony/chrony -v
    chronyd (chrony) version 4.1-monogon (NTP RTC SCFILTER ASYNCDNS)

Monogon Monorepo

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

⚠️ This is pre-release software that happens to be publicly available. Nothing to see here, please move along.

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 //...
