[Docker] “unsafe repository” when building the Docker image.

Khi bạn build docker image thì bị báo lỗi bên dưới.

fatal: unsafe repository ('/repo' is owned by someone else)
10:20:47  To add an exception for this directory, call:
10:20:47  
10:20:47  	git config --global --add safe.directory /repo
10:20:47  BUILD ...
10:20:47  BUILD: 0000000
10:20:47  error obtaining VCS status: exit status 128
10:20:47  	Use -buildvcs=false to disable VCS stamping.
10:20:47  BUILD DONE!

như trong log đã hướng dẫn thì chúng ta cần thêm
RUN git config --global --add safe.directory /repo
