I am trying to create docker container using dockerfile where script-entry.sh is to be executed when the containers starts and script-exit.sh to be executed when the container stops.
ENTRYPOINT helped to accomplish the first part of the problem where script-entry.sh runs on startup.
How will i make sure the script-exit.sh is executed on docker exit/stop ?

For containers that are stopped, you can also start the container using the Docker start command and then run the Docker exec command.
When we try to run /bin/sh on a stopped container using docker exec , Docker will throw a No such container error. We have to transform the stopped Docker container into a new Docker image before we can inspect the internals of the container. We can transform a container into a Docker image using the commit command.
When this happens, the program will stop, and the container will exit. The container has been stopped using docker stop : You can manually stop a container using the docker stop command. The Docker daemon has restarted, and it terminated and restarted the container: Docker can restart containers if you need it to.
docker stop sends a SIGTERM signal to the main process running inside the Docker container (the entry script). So you need a way to catch the signal and then trigger the exit script.
See This link for explanation on signal trapping and an example (near the end of the page)
