Configuration reset to default upon start unless restarted

[bbaraniec]

Hi there,

I'm running docker for Windows on Windows 10 1809. Docker start automatically with Windows and then starts the Minecraft Classic. I've run docker with -v option for and mounting d:/mc:/data Issue that I'm having always after Windows restart docker start with default config. Server.properties will be set to default, ops.json and whitelist.json will be wiped out. While checking those files on host Windows machine they have proper values. I have to manually do: docker restart mc in order to get those files updated. Any idea what might be causing it?

That’s strange that it works as expected after a docker restart. If you don’t mind, can you post the output of docker inspect mc when it does that?

Hi,

Thank you for your time. Below you will find as output as Windows and docker just started.

Thanks. The interesting bit is

{ "Type": "bind", "Source": "/host_mnt/d/MC", "Destination": "/data", "Mode": "", "RW": true, "Propagation": "rprivate" }

and I'm wondering if there's some startup/race condition where the Docker HyperV VM hasn't yet attached its volume mount from /host_mnt/d/MC to your actual D:\MC path at that point. It would be ideal if Docker had a way to delay the startup of the containers when the whole system is first started...

[bbaraniec]

I've tried I think everything. If there is any race condition I can't find it.

well … I do have a similar issue 😄 no solution so far? My rcon port all the time. Starting the container -> rcon port was initially set to 25575 … changed it to 25576 -> saved -> restart container -> rcon.port setting is reverted.

FUNNY tho is, that all the other settings persist …
