m/p/supervisor: allow signalling supervised processes Using Command.Process.Signal to send signals to supervised processes creates a data race between the Start function (called by Run) which populates Command.Process and the access to that field. Introduce a new option for RunCommand which takes a signal channel and internally solves this race by first calling Start (at which point Command.Process is populated and will not be mutated) and then spawning a Goroutine which does the actual sending. This is safe at least on Linux since Go 1.7 [1].

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!
Our build environment is self-contained and requires only minimal host dependencies:
/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.
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
Run full test suite:
bazel test -c dbg //...
