SELinux is preventing chown from 'setattr' accesses on the directory _data.

*****  Plugin catchall (100. confidence) suggests   **************************

If ha úgy érzi, hogy chown számára engedélyezni kell setattr hozzáférést itt: _data directory alapértelmezésben.
Then ezt jelentenie kell, mint hibát.
Hogy engedélyezze ezt a hozzáférést előállíthat egy helyi szabálymodult.
Do
allow this access for now by executing:
# ausearch -c 'chown' --raw | audit2allow -M my-chown
# semodule -X 300 -i my-chown.pp

Comment 1 Daniel Walsh 2016-11-17 23:16:34 UTC 
What container storage are you using?  Can you specify :Z in the volumes section, to relabel the content?

      - mariadb:/var/lib/mysql:Z
Comment 2 Daniel Walsh 2016-11-17 23:17:51 UTC 
This could be a docker-compose issue. not sure how docker compose translates volume requests into docker. Or it could be something that is fixed in newer versions of docker.
