docker轻量级私有仓库registry

由于墙的存在，很多镜像下载不下来，不得以得靠梯子，但是又很不稳定，又不想每个月花钱，无奈。。。只好搞一个私有仓库临时暂存，避免重置VM后镜像又丢失。既然要搞docker仓库，当然首选是harbor，可怜博主这边没资源跑这个，只能用docker官方自带得registry，虽然没有健全得管理功能，但足够轻量给私人使用

registry部署

[root@VM-8-17-centos ~]# mkdir /data/registry
[root@VM-8-17-centos ~]# docker run -d -p 5000:5000 --restart=always -v /data/registry:/var/lib/registry --name registry registry

使用nginx代理

此处使用nginx有两个功能：

提供ssl
提供basic认证

创建basic认证文件

# 安装httpd-tools提供htpasswd命令
yum install httpd-tools -y
# 设置用户/密码为： test/test1234
htpasswd -cb registry.htpasswd test test1234

准备ssl证书

# 此处使用阿里云得免费证书，读者可以自行创建私有证书也可，略
[root@VM-8-17-centos ~]# ll /www/server/panel/vhost/cert/
