m/n/c/curator/watcher: init

curator/watcher is a new library which simplifies access to the Curator
from client code.

It implements common logic found in a bunch of Metropolis code, where a
node or multiple nodes are watched for updates. The single-node version
of this RPC is not that complex, but the many-node version is and
definitely deserves a client library to remove possible sources of
implementation bugs.

This doesn't yet switch over any of the existing code to use this
library - that will come up in another CR on the stack.

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

Run a single node demo cluster

Build CLI and node image:

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

Launch an ephemeral test node:

bazel test //:launch --config 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 --config dbg //...
