6 Passing options to the server

$ docker run --name test -e MYSQL_ROOT_PASSWORD=root -v $(pwd)/cos-db:/var/lib/mysql -d mysql/mysql-server:5.6 --explicit_defaults_for_timestamp=true

7 Mount host dir

• place the dumped data file tempdb-xxx.sql in host dir cos-db/
• not support the sym link

comcat@aisrv:/work/api.noduino/database$ docker run --name mysql -e MYSQL_ROOT_PASSWORD=root -v $(pwd)/cos-db:/var/lib/mysql -d mysql/mysql-server:5.6

$ cat cos-db/getdevid.sql
select dvid from temp where productid='NNN1234' and uploadtime>'2017-03-01 00:00:00';
