Allow Spec to depend on Docker containers. Hspec takes care of initialization and de-initialization of the containers.

containers :: MonadDocker m => m Boolean
containers = do
  _redis <- TestContainers.run $ TestContainers.containerRequest TestContainers.redis
  _kafka <- TestContainers.run $ TestContainers.containerRequest TestContainers.kafka
  pure True

example :: Spec
example =
  around (withContainers containers) $ describe "Example tests"
    it "first test" $ \isBoolean -> do
      isBoolean shouldBe True

withContainers allows you naturally scope the handling of containers for your tests.
