   > > great . but dockerfile can use mysql ? mysql license is gpl . please check
   > 
   > Although MySQL is owned by the Oracle company, we usually discuss MySQL only in the community server edition, it is open-source, we only use its client tools, if you think we should not use it, we have other options, use MariaDB-client, It is 100% compatible with MySQL.
   
   MariaDB is distributed under the GPL license, version 2. The MariaDB client libraries for C, Java and ODBC are distributed under the LGPL license, version 2.1 or later. The LGPL license allows you to distribute these MariaDB client libraries freely with any application.
   
   so we can't use MariaDB client, GPL or LGPL not compitable with Apache license
   
   By the way, I have updated this PR
