SIGTERM detection

[mmonj]

When i do docker compose down the server is killed without the server saving its state. Is there any way that it can detect the SIGTERM signal and save the state immediately?

The problem isn't the signal, all relevant signals are properly passed through to the server process. The problem is very likely that your Docker daemon kills the container before the Valheim server can save the world to disk because the default timeout is 10s. That's why the docs say to start the container with --stop-timeout 120.

I just got passed an issue where state was not saving upon docker stop, even with proper timeouts, in an Azure ubuntu 24 VM, once I rolled back to ubuntu 22, it worked again, I didn't get the chance to investigate further tho.

I monitored the logs after docker stop and got nothing, container wouldn't log anything and then would just exit.
