Signal to nginx process

[hrsantiago]

Hello, I've been using Lapis inside a Docker container and it works just fine.
However I'm having trouble stopping and restarting the container because the signals are not passed to the nginx process.

The commands:
docker stop container_name docker restart container_name

Sends the signal TERM to the lapis process, however it does not forward the signal to the nginx process.

I see that I can do the following:

docker exec -ti container_name lapis signal 3

And it'll pass the signal 3 (QUIT) to the nginx and finish properly.
This way I can safely finish some code. Eg:

while not ngx.worker.exiting() do

Is there any reason for Lapis not forwaring all signals to nginx?
