Subject Docker PID 1
Date Mon, 10 Apr 2017 16:00:15 GMT

I was playing about with flink using the docker images provided,
however I noticed that the entry point is a bash script.

There is a problem in using bash as the PID1 process in a docker
container as docker sends SIGTERM, but bash doesn't send this to its
child processes.

This means for example that if a container was ever killed and a child
process had a file open then the file may get corrupted.

It's covered in more detail in a blog post here:

If this is a big enough concern should I raise a jira ticket?
