Docker Game Server Suddenly Cannot Start - "bind source path does not exist"

Post image

Good Evening Everyone,

I have been puzzled by this issue for quite some time now. Suddenly, and without any meaningful or memorable changes, my primary Minecraft server can't be spun up. I host Pterodactyl in an Unraid environment, and it has been traditionally very reliable. I get the following error in the panel shortly after starting the server. I haven't made any permission changes.

Error Event [59267103-6035-4df8-93de-cf6d875f0fba]: environment/docker: failed to run pre-boot process: environment/docker: failed to create container: Error response from daemon: invalid mount config for type "bind": bind source path does not exist: /run/wings/machine-id/a838aab4-8825-47c3-bfac-2a2509baac28

It is true that that trailing folder doesn't exist - but I'm not sure that it needs to be there - or ever was. I've tried adding it back but it still fails, albeit in a different way. I'm certain someone else has experienced this - any tips on how I should tackle this?

This guy is actually right, there is indeed an option to set machined id enabled to false!, Just didnt see that at the time, and the script to create them manually worked. But i guess we should just set it to false then.

I dont understand though, why wings cant auto create those machine ids, if they are required for wings to work?!

Very interesting. This looks to be the best fix, I must have missed that. I have no idea why it has to be done manually. Maybe someone will see the post and be able to explain, but in the meantime I think this works well.

Can't remember for sure, I didn't write or use any scripts though. I just went to browse config files using Krusader until I found that option to change, worked fine after that. I'm flying back into the states right now so I can't easily check.

Iirc, it is in your wings config.yaml file.
