在工件中配置 docker 虚拟存储库

Question

我有一个本地 docker 存储库和一个远程 docker 存储库，我创建了一个结合两者的虚拟 docker 存储库。为了从客户端访问此存储库，是否也需要将其添加到反向代理中？

这是当前的反向代理配置

 upstream artifactory_lb {

        server myserver.mycompany.com:8081 backup;
        server myserver.mycompany.com:8081;
}

        listen 443  ssl;

        location / {
                proxy_set_header Host $host;

                stub_status on;
                allow all;
                }
}

# Server configuration

server {
    listen 2222 ssl;

    if ($http_x_forwarded_proto = '') {
        set $http_x_forwarded_proto  $scheme;
    }

    rewrite ^/(v1|v2)/(.*) /api/docker/myrepo_images/$1/$2;
    client_max_body_size 0;
    chunked_transfer_encoding on;

    location / {
    allow all;s
    proxy_read_timeout  900;
    proxy_pass_header   Server;

    proxy_pass http://artifactory_lb/artifactory/;

    }
}

是的。 Docker 注册表仅由其主机名引用。这意味着您需要在反向代理中使用两个具有不同主机名的虚拟主机（使用 server_name directive），映射到不同的 Artifactory 存储库。

以下示例配置（缩短）应该可以解决问题：

server {
    listen 2222 ssl;
    server_name local-repo.my-artifactory.com;

    rewrite ^/(v1|v2)/(.*) /api/docker/myrepo_images/$1/$2;

    # <insert remaining configuration directives here>
}

server {
    listen 2222 ssl;
    server_name virtual-repo.my-artifactory.com;

    rewrite ^/(v1|v2)/(.*) /api/docker/myrepo_virtual/$1/$2;

    # <insert remaining configuration directives here>
}

现在您应该可以使用常规 docker 命令访问两个注册表：

$ docker pull virtual-repo.my-artifactory.com:2222/foo/bar:latest
$ docker pull local-repo.my-artifactory.com:2222/foo/bar:latest
$ docker push local-repo.my-artifactory.com:2222/foo/bar:latest
