m/n/c/clusternet: add clusternet node ip to lo

Without this address the kernel will send all traffic through clusternet
will with the external IP as source address, which prevents any access
from the k8s api-server to pods. By adding the address to the lo
interface, the kernel decides that this is the best match for the
generic clusternet route and uses it as source address.

Before: 10.192.1.2 dev clusternet src 233.252.0.1
After: 10.192.1.2 dev clusternet src 10.192.0.1

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 (or a working Nix environment).
  • 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

The source code lives in //metropolis (Metropolis is the codename of Monogon OS).

See the //metropolis/README.md for a developer quick start guide, or see the Monogon OS Handbook for user documentation.
