Docker Registry V2 with Nginx
安装 nginx修改/etc/yum.repos.d/nginx.repo
name=nginx repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=0
enabled=1
其中 releasever basearch 到 http://nginx.org/packages/centos/ 地址上去查
yum install nginx
配置ssl证书
注意CN的地址要与你的registry地址一致，可以修改/etc/hosts来绑定一个地址
修改 /etc/docker/daemon.json
增加 "insecure-registries":["xxx(CN里写的地址):port"]
正常启动registry 不需要任何ssl参数，权限交由nginx控制
docker run -d -p 6000:5000 --restart=always --name registry registry:2.5.1
配置nginx

}
}
}
其中
/root/registry/nginx/nginx.htpasswd
生成方法 htpasswd -cb nginx.htpasswd tester1 123456
登陆验证
docker login xxxx:port
curl -i -k -v https://uname:password@xxx:port/v2/_ping
问题解决：
502 问题
nginx后台日志
connect() failed (111: Connection refused) while connecting to upstream
而且upstream总是80端口
修改proxy_pass，这里修改成了http://registry 是一个不存在的地址
client sent plain HTTP request to HTTPS port while reading client request headers
peer closed connection in SSL handshake (104: Connection reset by peer) while SSL handshaking,
或者registry log ： registry first record does not look like a TLS handshake
关闭所有registry的ssl选项，所有SSL控制交给nginx处理
registry报错 Invalid token
需要在启动时设置REGISTRY_HTTP_SECRET,所有replica都使用相同的值即可（-e REGISTRY_HTTP_SECRET=mysk）
registry报错 blob unknown
后端数据要存放在一个数据源上，比如NFS，ceph
