Container doesn't stop on SIGINT

[sycured]

The container needs to stop on SIGINT (CTRL+C)

How to reproduce

1. Start the container using docker run --rm -p 8080:8080 geosolutionsit/geoserver:2.19.1
2. Waiting to see:

INFO [main] org.apache.coyote.AbstractProtocol.start Starting ProtocolHandler ["http-nio-8080"]
INFO [main] org.apache.catalina.startup.Catalina.start Server startup in [30964] milliseconds
catalina.sh run

3. Doing SIGINT doing CTRL+C, you'll see something like: ^C^C^C^C^C^C^C^C^C^C (one for each time you send it)

Expected behavior

The container stop on receiving SIGINT

Actual behavior

SIGINT isn't handled and the container needs to be stopped using docker stop via another terminal

Workaround

Starting the container using --init flag: docker run --rm --init -p 8080:8080 geosolutionsit/geoserver:2.19.1

Possible fix

• updating the documentation about --init flag
• using an init directly inside the container like s6-overlay

that's interesting I don't see a strong enough point to add this external dependency to the image

Thank you anyway
