m/test: implement SOCKS proxy in cluster tests

This uses the new socksproxy package to run a proxy server in the
nanoswitch, and uses it within tests to access the test cluster's nodes.

The cluster test code (and nanoswitch) still forward traffic to the
first node, but this will be gradually removed as SOCKS support is
implemented in metroctl and the debug tool. Forwards from host ports to
different node can then be implemented as part of the dbg tool (instead
of the cluster launch code) to maintain a simple interface during debug
and development.

We also use the opportunity to make the non-cluster launch code not
Metropolis specific (by removing an assumption that all ports on all
nodes are Metropolis ports). In the long term, we will probably remove
non-cluster launches entirely (or further turn this code into just being
a 'launch qemu' wrapper).

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 //...
