WORKDIR /srv
RUN apk add --no-cache curl \
 && curl -fsSLO https://github.com/snsinfu/ftrap/releases/download/v0.3.0/ftrap \
 && chmod u+x ftrap
CMD ["/srv/ftrap", "-f/srv", "sleep", "100"]

Build and run:

docker build -t ftrap_test .
docker run -it --rm ftrap_test

Then, press Ctrl-C. It triggers the assertion failure:
