m/node/core: run hostsfile from roleserver, provide feedback on cluster directory

Not providing a heartbeat and status until we save a cluster directory
to ESP is a quick and dirty way to make sure we don't mark a node as
HEALTHY until it has performed the bare minimum of setup to be
rebootable.

This is important in our E2E tests to reduce flakiness.

In the future we should have some node status field or general 'sync'
API exposed, but this will do for now.

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 //...
