Hey @JY-Zhou and @mastrodaro, sorry for the very late reply.

[CRITICAL] Failed to save file: /home/dst/.klei//DoNotStarveTogether/DSTWhalesCluster/Master/save/saveindex

This looks like a permission error. Does the user that's running docker also have write permissions in the dst-dedicated-server folder? Ideally, the user you use to clone and set up the project should be the same one running the docker containers.

Check the Docker Linux installation in the docs, specially the post-installation steps to grant your user permission to run docker.

Others had problem with this before using one user to git clone and setup the project (e.g. root) and then they try to run this as another user.

Please double check all the above and let me know if you're still having the issue!

try this command:
docker-compose up -d && docker exec -u root -it dst_master bash -c "chown -Rv dst:dst /home/dst/.klei/DoNotStarveTogether"

the problem is the volume mount owner doesn't correct. the command fixes the owner to dst:dst.

Thanks this worked for me. I also added chown -Rv dst:dst /home/dst/server_dst/mods as I also had some permission errors when I was trying to install mods.
This did the trick.

docker-compose up -d && docker exec -u root -it dst_master bash -c "chown -Rv dst:dst /home/dst/.klei/DoNotStarveTogether && chown -Rv dst:dst /home/dst/server_dst/mods"
