docker registry v2 nginx 安全访问控制
环境准备：
docker 版本：1.9.1
registry版本：2.2.1
本文之前也有发过一篇自建仓库nginx认证，但是对新出的registry v2版本不适用，特重更一篇。
一、创建相关目录及文件
(1)目录结构
auth
│ ├── domain.crt
│ ├── domain.key
│ ├── nginx.conf
│ └── nginx.htpasswd
├── data
|
1
2
3
|
mkdir -p auth
mkdir -p data
openssl req -newkey rsa:4096 -nodes -sha256 -keyout auth/domain.key -x509 -days 365 -out auth/domain.crt
|
例如：
|
1
2
3
4
5
6
7
8
9
|
Country Name (2 letter code) [AU]:China
string is too long, it needs to be less than 2 bytes long
Country Name (2 letter code) [AU]:CH
State or Province Name (full name) [Some-State]:BeiJing
Locality Name (eg, city) []:BeiJing
Organization Name (eg, company) [Internet Widgits Pty Ltd]:BeiJing
Organizational Unit Name (eg, section) []:BeiJing
Common Name (e.g. server FQDN or YOUR name) []:registry.test.com
Email Address []:[email protected]

(2)生成对应nginx配置文件

(3)创建登录用户文件

|
htpasswd -cb auth/nginx.htpasswd admin admin
|
(4)使用docker-compose启动
