下面我们进入正题。
Step 1:前置条件
- 已安装docker环境
- 已安装Harbor镜像服务器
Step 2:拉取mysql官方镜像库
[root@harbor ~]# docker search mysql

一，准备4个文件:

!includedir /etc/mysql/conf.d/
!includedir /etc/mysql/mysql.conf.d/
lower_case_table_names=1
character-set-server=utf8
Dockerfile docker镜像构建文件
FROM mysql:5.7
COPY ./my.cnf /etc/mysql/
COPY ./*.sql /mysql/
COPY setup.sh /opt/setup.shCMD ["sh", "/opt/setup.sh"]
EXPOSE 3306
privileges.sql mysql远程登陆及密码配置文件
use mysql;
grant all privileges on *.* to root@"%" identified by "root" with grant option;
flush privileges;
setup.sh docker镜像启动的第一个执行脚本
#!/bin/bash
set -eecho '1.启动mysql....'
service mysql start
sleep 3
echo `service mysql status`
echo '1.启动mysql完毕....'echo '4.开始修改密码....'
mysql < /mysql/privileges.sql
echo '5.修改密码完毕....'
tail -f /dev/null
二，构建镜像:
准备的文件及路径
[root@harbor mysql]# pwd
/root/docker-images/mysql
[root@harbor mysql]# ll
total 16
-rw-r--r-- 1 root root 134 May 6 19:45 Dockerfile

-rw-r--r-- 1 root root 245 May 6 19:49 setup.sh
开始构建
[root@harbor mysql]# docker build -t iam-mysql:5.7 -f Dockerfile .

Step 4:上传到镜像服务器
镜像源配置信息,登录私服
[root@harbor mysql]# cat /etc/docker/daemon.json
{
"registry-mirrors": ["https://9exvf3nd.mirror.aliyuncs.com"],
"insecure-registries": ["192.168.0.240:80"]
}
[root@harbor mysql]# docker login 192.168.0.240:80
打tag,并上传
[root@harbor mysql]# docker tag iam-mysql:5.7 192.168.0.240:80/iam/mysql:5.7
[root@harbor mysql]# docker images
