Hi, 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: https://blog.phusion.nl/2015/01/20/docker-and-the-pid-1-zombie-reaping-problem/ If this is a big enough concern should I raise a jira ticket? Kat
