metropolis: use new OS image format for updates

This switches the node update implementation to the new OS image format
based on OCI artifacts. Updates are now fetched from an OCI registry.

To update existing clusters, build //metropolis/node:bundle in the new
version, then run the update command of the old version of metroctl with
this bundle. Once a node is updated, it only accepts updates in the
new format. It is possible to rollback if needed by building
//metropolis/node:oci_image in the old version and using the new version
of metroctl.

The node bundle target is no longer referenced anywhere, and will be
removed soon.

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! In the meantime, join us on Matrix (#monogon-os-community:matrix.org) or Discord.

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

The source code lives in //metropolis (Metropolis is the codename of Monogon OS).

See the //metropolis/README.md for a developer quick start guide, or see the Monogon OS Handbook for user documentation.
