m/p/devicemapper: Support creating read-only devices

I originally thought this is not going to be needed as R/W control can be done through devicemapper itself, but verity requires a read-only table.

While we're here let's also add some doc comments to the Target struct.

Existing functionality is covered by existing tests, read-only functionality will be exercised by verity tests once they land.

Monogon Monorepo

This is the main repository containing the source code for the Monogon Project.

⚠️ This is pre-release software that happens to be publicly available. Nothing to see here, please move along.

Environment

Our build environment requires a working Podman binary (your distribution should have one).

Usage

Spinning up: scripts/create_container.sh

Spinning down: scripts/destroy_container.sh

Running commands: scripts/run_in_container.sh <...>

Using bazel using a wrapper script: scripts/bin/bazel <...> (add to your local $PATH for convenience)

IntelliJ

This repository is compatible with the IntelliJ Bazel plugin, which enables full autocompletion for external dependencies and generated code. All commands run inside the container, and necessary paths are mapped into the container.

The following steps are necessary:

  • Install Google's Bazel plugin in IntelliJ. On IntelliJ 2020.3 or later, you need to install a beta release of the plugin.

  • Add the absolute path to your ~/.cache/bazel-monogon folder to your idea64.vmoptions (Help → Edit Custom VM Options) and restart IntelliJ:

    -Dbazel.bep.path=/home/leopold/.cache/bazel-monogon

  • Set "Bazel Binary Location" in Other Settings → Bazel Settings to the absolute path of scripts/bin/bazel. This is a wrapper that will execute Bazel inside the container.

  • Use File → Import Bazel project... to create a new project from .bazelproject.

After running the first sync, everything should now resolve in the IDE, including generated code.

Metropolis

Run a single node cluster

Launch the node:

scripts/bin/bazel run //:launch

Run a kubectl command:

scripts/bin/bazel run //metropolis/cli/dbg -- kubectl describe

Run tests:

scripts/bin/bazel test //...
