Gogs 是 一个能够简单自建Git托管服务的开源项目，用 go 语言实现。
Gogs 官方地址
概况
- 掌握了如何运用Docker安装启动 Gogs
- 掌握了如何运用Docker安装启动 Mysql
- 掌握了如何使用Docker compose 命令整合 Gogs & Mysql 两个容器
MySQL 镜像的下载、启动容器
- 从默认的仓库拉取mysql镜像：
docker pull mysql - 查看本地有哪些镜像：
docker images - 运行mysql镜像生成名字叫做mysql2的容器，映射主机端口是13306，root密码是123456 ：
docker run - 查看本地创建了哪些容器
docker ps - 交互方式进入mysql2容器的shell环境，创建一个数据库testdb
docker exec
[root@localhost ~]# docker pull mysql
[root@localhost ~]# docker images

Gogs 的配置和使用
-
打开chrome 浏览器，输入网址 ：http://192.168.1.161:10080/
-
第一次访问Gogs，浏览器进入安装页面，如图所示填写字段：
Paste_Image.png
Paste_Image.png
-
编辑 Gogs 配置文件（
vi /var/gogs/gogs/conf/app.ini）
修改 ROOT_URL = http://192.168.1.161:10080/
......
[server]
DOMAIN = 192.168.1.161
HTTP_PORT = 3000
ROOT_URL = http://192.168.1.161:10080/
DISABLE_SSH = false
SSH_PORT = 10022
OFFLINE_MODE = false
......
问题：为什么可以修改 Host 的 /var/gogs/ 目录的文件，就可以改变容器里的配置文件？
答案：因为启动容器的时候，我们使用 -v /var/gogs:/data 把 Host 里的目录 /var/gogs 挂载到容器的/data/目录
