詳解利用Dockerfile構(gòu)建mysql鏡像并實(shí)現(xiàn)數(shù)據(jù)的初始化及權(quán)限設(shè)置

#設(shè)置容器啟動(dòng)時(shí)執(zhí)行的命令

#查看mysql服務(wù)的狀態(tài)，方便調(diào)試，這條語(yǔ)句可以刪除

-- 因?yàn)閙ysql版本是5.7，因此新建用戶為如下命令：
create user docker identified by '123456';
-- 將docker_mysql數(shù)據(jù)庫(kù)的權(quán)限授權(quán)給創(chuàng)建的docker用戶，密碼為123456：
grant all on docker_mysql.* to docker@'%' identified by '123456' with grant option;
-- 這一條命令一定要有：
flush privileges;

docker build -t 13/docker-mysql .

docker run -d -p 13306:3306 13/docker-mysql
