Docker signal handling

Caveat (aka Known Issues)

Whereas this works, wait-for-signals-2.sh (commented out as ENTRYPOINT in Dockerfile) will not react to signals. See related Docker issues.

How to run this spike

Build:

docker build -t test-sigint .

Run as "int":

docker run --name int --rm test-sigint 4
echo "Exit code: $?"

or in the background:

docker run --name int -d test-sigint 4

Monitor and kill:

docker ps
docker kill -s INT int
docker stop -t 8 int
