m/n/k/reconciler: implement updates

The reconciler now checks if already present object are equal to the 
expected object, and else updates them. If the update fails due to 
immutable fields, the object is instead deleted and recreated.

Also, the reconciler now logs create/update/delete operations.

For the CSI driver, the StorageCapacity and RequiresRepublish were added 
and set to their default value. If we don't do this, the API server will 
add these defaults, and then our update comparison fails. There is also 
a new test which ensures that expected objects have all defaults already 
applied. This test will fail if a Kubernetes upgrade adds new fields 
with default values.

Closes #288.

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.

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.
