docker - 如何在 Apache httpd 后面公开 Docker-Registry？

问题描述

我正在使用以下docker-compose.yml文件运行私有 docker-registry v2：

registry:
  restart: always
  image: registry:2
  ports:
    - 5000:5000
  environment:
    REGISTRY_HTTP_TLS_CERTIFICATE: /certs/server-cert.pem
    REGISTRY_HTTP_TLS_KEY: /certs/server-key.pem
    REGISTRY_AUTH: htpasswd
    REGISTRY_AUTH_HTPASSWD_PATH: /auth/htpasswd
    REGISTRY_AUTH_HTPASSWD_REALM: Registry Realm
  volumes:
    - /data/docker-registry:/var/lib/registry
    - /certs/docker-registry:/certs
    - /auth/docker-registry:/auth

我可以在http://localhost:5000本地登录（SSH，Jenkins，...） 。

现在我想用 Apache httpd 公开这个注册表。我在 CentOS 7 上运行以下版本的 httpd：

[root@dev-machine conf.d]# httpd -v
Server version: Apache/2.4.6 (CentOS)
Server built:   Jun 27 2018 13:48:59

这是我的vhosts.conf：

<VirtualHost *:443>
    ServerName dev-machine.com
    ServerAlias www.dev-machine.com

    ErrorLog logs/dev-machine.com-error_log
    CustomLog logs/dev-machine.com-access_log common

    SSLEngine on
    SSLCertificateFile /certs/docker-registry/server-cert.pem
    SSLCertificateKeyFile /certs/docker-registry/server-key.pem

    Header set Host "dev-machine.com"
    Header set "Docker-Distribution-Api-Version" "registry/2.0"
    RequestHeader set X-Forwarded-Proto "https"

    ProxyRequests off
    ProxyPreserveHost on

    ProxyPass           /registry       http://127.0.0.1:5000/
    ProxyPassReverse    /registry       http://127.0.0.1:5000/

    <Location /registry>
        Order deny,allow
        Allow from all

        AuthName "Registry Authentication"
        AuthType basic
        AuthUserFile "/auth/htpasswd"
        Require valid-user
    </Location>
</VirtualHost>

我面临的问题是，当我尝试登录注册表时，出现以下错误：

izio@1z10:~$ docker login https://dev-machine.com/registry
Username: user
Password: 
Error response from daemon: login attempt to https://dev-machine/v2/ failed with status: 404 Not Found

似乎重定向到 /v2 而不是在 vhosts 中使用分配的 url。此配置有什么遗漏或错误？

解决方案

只需像这样更新您的 httpd.conf


ProxyPass /registry http://127.0.0.1:5000/ v2
ProxyPassReverse /registry http://127.0.0.1:5000/ v2
