t/linux: patch out static virtual interfaces

A few virtual drivers (bonding, dummy) predate netlink (~2003), which
means that the kernel had no way to dynamically create network
interfaces.
The solution was kernel module paramter which statically precreated a
list of these virtual interfaces. The number was generally set to 1 by
default, meaning that loading the module creates one of its interface.

For compatibility with legacy userspaces this is still kept around. We
could set the parameters to zero, but doing that everywhere is a pain.
This just patches the default values to zero.

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 //...
