安装mysql

创建网络

为了使多个docker之间通信，需要创建docker网络

docker network create backend 查看所有

docker network ls

下载镜像

参考上面的命令示例

存放数据文件

mkdir /data/mysql/data

存放配置文件

mkdir /data/mysql/conf

文件内容

/data/mysql/conf目录下建立3个mysql配置文件 docker.cnf, mysql.cnf, mysqldump.cnf

docker.io/mysql进入到mysql docker容器

SHOW DATABASES;

mysql -u root -p

密码为: root

创建一个库 CREATE DATABASE 库名;

然后删除docker docker stop mysql docker rm mysql

再次创建后查看是否存在库，存在则创建完成

安装gogs

mkdir -p /data/gogs

配置方式

遇到一个坑，当转发端口时的配置方式为

proxy_pass http://gogs:3000;

网关名称:内部端口号

docker-composecentos有pyhone2.7，但是没有pip，先安装一下，顺手再升级一下。

yum install python-pip

pip install --upgrade pip

安装compose

pip install docker-compose

检查一下版本

docker-compose version

配置

新建文件docker-compose.yml1
