How can i receive signal in the jvm?

See original GitHub issue

I use /bin/bash to run jvm as a child process, but i can’t receive signal in the jvm.

Dockerfile:

ENTRYPOINT ["/dumb-init", "--", "/docker-entrypoint.sh"]

and docker-entrypoint.sh:

#!/usr/bin/dumb-init /bin/bash

source `dirname $0`/init-product.sh

if [ -z "$POOL_TYPE" ]; then
  source `dirname $0`/init.sh $RESOURCE_ID
  echo "****FINISHED****"
else
  echo "****FINISHED****"
  java -Xmx64m -Xms16m -Xmn8m -Xss1m -XX:ReservedCodeCacheSize=5m -XX:NewRatio=3 -jar /usr/local/agent/agent-1.0.1.jar $POOL_TYPE
fi

yep that looks correct as long as you have the ENTRYPOINT set as OP does

@asottile // @VFT Quick followup question, when you mention unnecessary /bin/bash in the shebang do you mean it should be completely omitted? What should it look like when done correctly based on your directions

Is this correct for the process tree or since entry-point defines dumb-init does this inherit correctly?

#!/bin/bash

source `dirname $0`/init-product.sh

if [ -z "$POOL_TYPE" ]; then
  source `dirname $0`/init.sh $RESOURCE_ID
  echo "****FINISHED****"
else
  echo "****FINISHED****"
exec java -Xmx64m -Xms16m -Xmn8m -Xss1m -XX:ReservedCodeCacheSize=5m -XX:NewRatio=3 -jar /usr/local/agent/agent-1.0.1.jar $POOL_TYPE
fi
