m/node: enlarge K8s networks

For bigger clusters, the current 10.0.0.0/16 subnet is far too small.
Switch to 10.192.0.0/11 which should be out of the way of most of our
test infra and is large enough for 8192 nodes with 253 pods which is
big enough for the time being. Also migrate the service network
to 10.224.0.0/16 and make it much bigger. It does not need to be in the
pod CIDR, so move it out of there.
But for large clusters this will continue to be a problem until we have
a better allocation algorithm or switch to IPv6 with 464xlat (which
is not supported on Linux currently however).

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 //...
