c/takeover/e2e: add takeover end-to-end test

This adds an end-to-end test to the takeover system.
It launches a QEMU VM running a Debian Cloud Image which is configured
via cloud-init to accept SSH access from the test.
It connects to that VM via SSH, copies the takeover binary under test
to it via SFTP and launches it.
It passes a test TakeoverInit message to it, performs basic sanity
checking on the response and then looks on the serial port for a flag
mesage that the agent has started.

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 //...
