Docker下使用Dockerfile基于centos基础镜像构建mysql-8.0容器镜像
2021年09月07日 Docker 暂无评论 ⁄ 被围观 418次+

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

#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。
