Docker ps status Exited (255)


I am new to Docker. I have a Spring Boot application running a job. When I start the app everything works fine except, it exits with status 255 after running for say 30 mins. After the job finishes it will sleep for sometime. However, the job is not even completing.

$ docker ps -a
CONTAINER ID        IMAGE                     COMMAND                  CREATED             STATUS                        PORTS               NAMES

$ docker --version

$ docker-machine --version
docker-machine version 0.12.2, build 9371605

I don’t see any error in the container logs. Did a little bit of research for exit status 255 but couldn’t find anything helpful.

Any ideas what the status means and how I can debug this issue on my end?

Thanks in advance for your help.
