docker封装mysql镜像

一、概述

直接使用官方的镜像

docker pull mysql:5.7

但是mysqld.cnf并没有优化，还是默认的。

二、封装镜像

创建目录

# dockerfile目录
mkdir -p /opt/dockerfile/mysql
# 持久化目录
mkdir -p /data/mysql/data

/opt/dockerfile/mysql 目录结构如下：

./
├── dockerfile
├── mysqld.cnf
└── run.sh

dockerfile

FROM mysql:5.7
ADD mysqld.cnf /etc/mysql/mysql.conf.d/mysqld.cnf

生成镜像

cd /opt/dockerfile/mysql
docker build -t mysqld_prod:5.7 .

启动镜像

bash run.sh
