make run failed on ADD TDB_*.sql

[hurr1k4ne]

Ubuntu 18.04 Beta
complete new install on Xeon 6-Core / 16GB Ram
commands were run as normal "non-root" user

make build
make mapdata
ran without failure

step make run stops at worldserver, when adding TDB Database to docker image

Step 14/17 : ADD TDB_*.sql "${install_prefix}/bin/" ERROR: Service 'worldserver' failed to build: ADD failed: stat /var/lib/docker/tmp/docker-builder178854865/artifacts/sql/TDB_full_world_335.64_2018_02_19.sql: no such file or directory Makefile:125: recipe for target 'run' failed make: *** [run] Error 1

i came so far, but now i am a bit clueless why it could not find the file?

ls -lah artifacts/sql/TDB_full_world_335.64_2018_02_19.sql -->
-rwxrwxrwx 1 root root 250M Apr 14 12:44 artifacts/sql/TDB_full_world_335.64_2018_02_19.sql

Solution: do not use Symlinks!
copy that TDB_*.sql into trinitycore/docker/worldserver/
