Docker container sends false "unexpected termination" signal when script completes successfully.

[agambon]

When the script has finished successfully pulling the last status in the batch, the docker container stops. For some reason, the OS (Synology DSM) interprets this is a crash, and sends me critical alert notifications via email. I don't see a workaround on the OS side to exclude monitoring of a single container.

Is there a way to make the script shutdown the docker container more gracefully?
