docker registry v2 nginx 安全访问控制

3231212

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 []:BeiJing@beijing.com

(2)生成对应nginx配置文件

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51

cat <<EOF > auth/nginx.conf upstream docker-registry {       server registry:5000; } server {   listen 443 ssl;   server_name default_server;   # SSL   ssl on;   ssl_certificate /etc/nginx/conf.d/domain.crt;   ssl_certificate_key /etc/nginx/conf.d/domain.key;   # Recommendations from https://raymii.org/s/tutorials/Strong_SSL_Security_On_nginx.html   ssl_protocols TLSv1.1 TLSv1.2;   ssl_ciphers 'EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH';   ssl_prefer_server_ciphers on;   ssl_session_cache shared:SSL:10m;   # disable any limits to avoid HTTP 413 for large image uploads   client_max_body_size 0;   # required to avoid HTTP 411: see Issue #1486 (https://github.com/docker/docker/issues/1486)   chunked_transfer_encoding on;   location /v2/ {     # Do not allow connections from docker 1.5 and earlier     # docker pre-1.6.0 did not properly set the user agent on ping, catch "Go *" user agents        if (\$http_user_agent ~ "^(docker\/1\.(3|4|5(?!\.[0-9]-dev))|Go ).*\$" )     {               return 404;     }     # To add basic authentication to v2 use auth_basic setting.     auth_basic "Registry realm";     auth_basic_user_file /etc/nginx/conf.d/nginx.htpasswd;     ## If $docker_distribution_api_version is empty, the header will not be added.     ## See the map directive above where this variable is defined.     add_header 'Docker-Distribution-Api-Version' 'registry/2.0' always;     proxy_pass                          http://docker-registry;     proxy_set_header  Host              \$http_host;   # required for docker client's sake     proxy_set_header  X-Real-IP         \$remote_addr; # pass on real client's IP     proxy_set_header  X-Forwarded-For   \$proxy_add_x_forwarded_for;     proxy_set_header  X-Forwarded-Proto \$scheme;     proxy_read_timeout                  900;   } } EOF

(3)创建登录用户文件

1	htpasswd -cb auth/nginx.htpasswd admin admin

(4)使用docker-compose启动

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

cat <<EOF > docker-compose.yml nginx:   image: "nginx:latest"   ports:     - 443:443   restart: always   links:     - registry:registry   volumes:     - `pwd`/auth/:/etc/nginx/conf.d registry:   image: registry:2.2.1   ports:     - 127.0.0.1:5000:5000   restart: always   volumes:     - `pwd`/data:/var/lib/registry EOF

启动命令：

1 2 3 4 5

docker-compose up -d (5)验证 curl -i -k -v https://admin:admin@registry.test.com/v2/ 登录： docker login registry.test.com 查看上传的镜像信息： curl -i -k -v https://admin:admin@registry.test.com/v2/_catalog
