c/agent: implement

Implement the currently-required agent functionality, i.e. running with
both autoconfigured as well as static network configuration, interacting
with the BMaaS API and installing Monogon OS.

The early-stage setup is similar to Monogon OS itself, but after setting
up the root supervisor this instead calls into the agent runnable which
then performs the rest of the work.
In the process I made both logtree as well as supervisor public as they
are very generic and I see no reason to keep them scoped so tightly.
Maybe we should move them to go/ at some point.

This currently calls into osimage without the optimization the
regular installer performs, this is intentional as I have code which
will replace osimage with a high-performance version, obviating the
need to manually make this fast here.

This also comes with an end-to-end test
which exercises the whole flow, installing TestOS and checking if it
launches.

Monogon Monorepo

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

This is pre-release software - take a look, and check back later!

Environment

Our build environment is self-contained and requires only minimal host dependencies:

  • A Linux machine or VM.
  • Bazelisk >= v1.15.0
  • A reasonably recent kernel with user namespaces enabled.
  • Working KVM with access to /dev/kvm (if you want to run tests).

Our docs assume that Bazelisk is available as bazel on your PATH.

Refer to SETUP.md for detailed instructions.

Monogon OS

Run a single node demo cluster

Build CLI and node image:

bazel build //metropolis/cli/dbg //:launch -c dbg

Launch an ephemeral test node:

bazel test //:launch -c dbg --test_output=streamed

Run a kubectl command while the test is running:

bazel-bin/metropolis/cli/dbg/dbg_/dbg kubectl describe node

Test suite

Run full test suite:

bazel test -c dbg //...
