m/n/core/clusternet: grab external IP address prefix from network service

This moves the logic for merging the node IP and node prefixes from the
submitter of the prefixes into the clusternet logic itself.

This means clusternet now has two independent sources of prefix data:
the network service's external IP address, and the kubelet's node
prefixes.

This simplifies use in a worker/controller split, where a controller
node normally doesn't submit any prefixes as it's not running a kubelet
or kubelet-adjacent prefixes - but we still want it to submit its
external IP address.

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 //...
