Issue with spigot container when using external volume

[CedricAndry]

I installed nimmis/spigot Docker image on my Synology Diskstation and attached a specific volume to the container in order to save my Spigot server configuration.

Here is the volume attached : admin@DiskStation415:~/Minecraft_Docker$ ll total 22224 drwxrwxrwx+ 5 minecraft root 4096 Dec 18 11:09 . drwxr-xr-x 38 root root 4096 Dec 17 03:30 .. -rwxrwxrwx+ 1 minecraft users 1241 Dec 16 17:27 bukkit.yml drwxrwxrwx+ 3 minecraft root 4096 Dec 16 17:14 @eaDir -rwxrwxrwx+ 1 minecraft users 10 Dec 18 11:09 eula.txt drwxrwxrwx+ 2 minecraft users 4096 Dec 16 17:38 logs lrwxrwxrwx+ 1 admin users 17 Dec 17 11:19 minecraft.jar -> spigot-latest.jar drwxrwxrwx 8 minecraft users 4096 Dec 15 19:26 Mission QUOTAR -rwxrwxrwx+ 1 minecraft users 816 Dec 17 11:19 server.properties lrwxrwxrwx+ 1 admin users 17 Dec 18 11:09 spigot.jar -> spigot-latest.jar -rwxrwxrwx+ 1 minecraft root 22715741 Dec 16 17:30 spigot-latest.jar -rwxrwxrwx+ 1 minecraft users 3494 Dec 16 17:27 spigot.yml lrwxrwxrwx 1 admin users 36 Dec 17 11:50 world -> /volume3/@appstore/Craftbukkit/world

Here is the error and what is see in the stdout log file: root@nimmis-spigot:/var/log# cd supervisor

How can I match my host minecraft user and the container minecraft user?

[nimmis]

changing the minecraft user UID from 1000 (predefined) to 1035 can be fixed by running the following command inside the docker container

sed -i.bak 's/1000:1000/1035:1000/' /etc/passwd

you have an /etc/password.bak with the original value. do a

mc_restart

after.

But which user does the directory/files in /volume3/@appstore/Craftbukkit/world have as owner, user 1035/minecraft need to have write rights there.

Thanks a lot, this solve my issue with right for minecraft user. I am now stuck on another issue In /var/log/error: Dec 18 18:29:59 nimmis-spigot su[160]: pam_env(su:session): Unable to open env file: /etc/default/locale : No such file or directory

Java process does not spawn on this container.

[nimmis]

There was a bug in nimmis/ubuntu:14.04 where this file /etc/default/locale wasn't generated. I have updated the container with a fix so i will eventually rebuild nimmis/spigot, you can fix it in your container by running

/usr/sbin/update-locale

inside the container, that should fix the problem.
