一、CentOS 7.x 安装Docker-ce社区版本
https://www.osyunwei.com/archives/11592.html
二、准备安装软件包
cd /usr/local/src #建议先把需要安装的软件包下载到本地目录
下载mysql二进制安装包
wget https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-8.0.26-linux-glibc2.12-x86_64.tar.xz
三、构建mysql容器镜像
1、从docker hub拉取官方基础镜像
#我们用centos系统进行构建
https://hub.docker.com/_/centos?tab=tags&page=1&ordering=last_updated
选择centos:7.9.2009版本
docker pull centos:7.9.2009 #拉取系统镜像
docker image ls #查看docker镜像
docker run -itd --name centos centos:7.9.2009 #运行容器
docker ps #查看容器
[root@master01 src]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
3c79f14bf82f centos:7.9.2009 "/bin/bash" 8 seconds ago Up 7 seconds centos
docker exec -it 3c79f14bf82f /bin/bash #进入容器
exit #退出容器
2、编写Dockerfile构建文件
cd /usr/local/src #进入目录
vi /usr/local/src/dockerfile #dockerfile文件必须和上一步下载的软件包在同一目录
#基于这个镜像进行操作
FROM centos:7.9.2009
#作者和邮箱

#切换到根目录
WORKDIR /root
#设置mysql运行端口
EXPOSE 3306
#设置mysql前台方式运行
CMD ["/usr/local/mysql/bin/mysqld_safe"]
:wq! #保存退出
3、构建容器
docker build --no-cache -t osyunwei/mysql:8.0.26 /usr/local/src
或者
docker build -t osyunwei/mysql:8.0.26 .
4、运行容器
docker image ls #查看docker镜像
docker run -itd --name mysql osyunwei/mysql:8.0.26 #运行容器
docker ps #查看容器
[root@master01 src]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
16a32fac0b6f osyunwei/mysql:8.0.26 "/usr/local/mysql/bi…" 7 seconds ago Up 6 seconds 3306/tcp mysql
docker exec -it 16a32fac0b6f /bin/bash #进入容器
#测试mysql容器
#mysql免密登录
/usr/local/mysql/bin/mysql -p -S /tmp/mysql.sock
#设置root登录
create user root@'%' identified by '';
grant all privileges on *.* to root@'%' with grant option;
flush privileges;
exit #退出mysql
exit #退出容器
5、上传mysql容器镜像到阿里云容器仓库
docker image ls #查看镜像id
[root@master01 src]# docker image ls
REPOSITORY TAG IMAGE ID CREATED SIZE
osyunwei/mysql 8.0.26 63cbda15df45 5 minutes ago 2.87GB
5.1重命名镜像标签
docker tag 63cbda15df45 registry.cn-hangzhou.aliyuncs.com/osyunwei/mysql:8.0.26
#registry.cn-hangzhou.aliyuncs.com是阿里云容器仓库地址
#osyunwei是自己创建的命名空间
#mysql是自己创建的仓库名称
#:8.0.26是自定义php-fpm镜像的版本号
5.2登录阿里云仓库
docker login --username=你的阿里云登录账号 registry.cn-hangzhou.aliyuncs.com
[root@master01 src]# docker login --username=你的阿里云登录账号 registry.cn-hangzhou.aliyuncs.com
Password:刚才设置的固定密码
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store
Login Succeeded
[root@master01 src]#
5.3上传镜像到阿里云仓库
docker push registry.cn-hangzhou.aliyuncs.com/osyunwei/mysql:8.0.26
5.4拉取阿里云容器镜像
docker pull registry.cn-hangzhou.aliyuncs.com/osyunwei/mysql:8.0.26
至此，Docker下使用Dockerfile基于centos基础镜像构建mysql-8.0容器镜像教程完成。
