Livebook for testing:

Mix.install(
  [
    :kino,
    :flame,
    {:flame_k8s_backend, github: "mruoss/flame_k8s_backend", ref: "renovate/flame-0.x"}
  ],
  force: true
)

flame_k8s_backend_git_ref = "renovate/flame-0.x"
System.put_env("FLAME_K8S_BACKEND_GIT_REF", flame_k8s_backend_git_ref)
Kino.start_child!(
  {FLAME.Pool,
    name: :flame_test,
    code_sync: [
      verbose: true,
      copy_paths: true,
      sync_beams: [Path.join(System.tmp_dir!(), "livebook_runtime")]
    ],
    min: 1,
    max: 1,
    max_concurrency: 10,
    backend: FLAMEK8sBackend,
    idle_shutdown_after: :timer.minutes(5),
    log: :debug}
)


defmodule Foo do
  def test(args), do: "works #{inspect(args)} #{node()}"
end

FLAME.call(:flame_test, fn -> Foo.test(1234) end)

I had to add this hack in order to be able to test the Livebook integration. Maybe FLAME.Parent.new/5 could at some point allow to pass the backend_vrs.

and while at it the variable could also be renamed to backend_version so us normalo humans don't have to reverse engineer it 😜

Livebook integration works with the edge livebook docker image. There's a lot of noise but it works.
