Not responding to CTRL+C, and exit code is 137

[AxelBrinck]

Hello!

Thanks for building this awesome image!
I'm running your container with the following Dockerfile:

...
FROM joseluisq/static-web-server:2-alpine
RUN rm -rf /public/*
COPY --from=bundler /app/dist/automaton ./public
EXPOSE 80

The program is operating good at this point. But whenever I want to close it from terminal using CTRL+C it just doesn't respond. And I have to close it from Docker Desktop, resulting in 137 exit code. Which AFAIK means signal kill.

Is there a way to gracefully stop the server? If possible, reacting to CTRL-C...?

Thank you very much!

Can you share more context about how are you running the server via Docker?

Termination signaling (like ctrl+c) is supported. See the docs

Here is a small test

cat Dockerfile
FROM joseluisq/static-web-server:2-alpine
RUN rm -rf /public/*

# COPY --from=bundler /app/dist/automaton ./public

# EXPOSE 80

Note the ^C (ctrl+c) below

Sorry! I forgot to include -it flag to the docker command!
This container is awesome, very good project.
Thank you very much!
