url – Docker注册表的Artifactory主机名解析

2024-01-22 18:29:40

我正在尝试将Docker镜像推入Artifactory中新创建的docker repo.为此,我将图像标记如下,

docker tag ubuntu mNginxLb.mycompany.com/artifactory/api/docker/<repo_key>

然后推送图像但得到以下错误

docker push  mNginxLb.mycompany.com/artifactory/api/docker/<repo_key>/ubuntu

The push refers to a repository [mNginxLb.mycompany.com/artifactory/api/docker/<repo_key>/ubuntu] (len: 1)
unable to ping registry endpoint https://mNginxLb.mycompany.com/v0/
v2 ping attempt failed with error: Get https://mNginxLb.mycompany.com/v2/: x509: certificate signed by unknown authority
 v1 ping attempt failed with error: Get https://mNginxLb.mycompany.com/v1/_ping: x509: certificate signed by unknown authority

这是证书签名机构还是主机名解析的问题？我检查了其他存储库是否与SSL证书配合良好,所以我不确定问题是否是证书.
这是我的nginx conf：

upstream artifactory_lb {
            server mNginxLb.mycompany.com:8081;
            server mNginxLb.mycompany.com backup;
    }

    log_format upstreamlog '[$time_local] $remote_addr - $remote_user - $server_name  to: $upstream_addr: $request upstream_response_time $upstream_response_time msec $msec request_time $request_time';

    server {
            listen 80;
            listen 443 ssl;

            ssl_certificate  /etc/nginx/ssl/my-certs/myCert.pem;
            ssl_certificate_key /etc/nginx/ssl/my-certs/myserver.key;
            client_max_body_size 2048M;
            location / {
                    proxy_set_header Host $host:$server_port;
                    proxy_pass http://artifactory_lb;
                    proxy_read_timeout 90;
            }
            access_log /var/log/nginx/access.log upstreamlog;
            location /basic_status {
                    stub_status on;
                    allow all;
                    }
    }

    # Server configuration

    server {
        listen 2222 ssl;

        server_name mNginxLb.mycompany.com;
        if ($http_x_forwarded_proto = '') {
            set $http_x_forwarded_proto  $scheme;
        }

        rewrite ^/(v1|v2)/(.*) /api/docker/my_local_repo_key/$1/$2;
        client_max_body_size 0;
        chunked_transfer_encoding on;
        location / {
        proxy_read_timeout  900;
        proxy_pass_header   Server;
        proxy_cookie_path ~*^/.* /;
        proxy_pass         http://artifactory_lb;
        proxy_set_header   X-Artifactory-Override-Base-Url $http_x_forwarded_proto://$host;
        proxy_set_header    X-Forwarded-Port  $server_port;
        proxy_set_header    X-Forwarded-Proto $http_x_forwarded_proto;
        proxy_set_header    Host              $http_host;
        proxy_set_header    X-Forwarded-For   $proxy_add_x_forwarded_for;
        }
    }

更新：

在CA将证书更新为一个之后,此错误消失了,尽管我仍然无法推送图像并获得403禁止错误.我使用的命令是

 docker push host:port/The push refers to a repository [host:port/image_name] (len: 1)
Sending image list

docker客户端给出以下错误
虽然神器日志显示以下内容

"GET /v2/ HTTP/1.1" 404 466 "-" "docker/1.9.1 go/go1.4.2 git-commit/a34a1d5 kernel/3.13.0-24-generic os/linux arch/amd64"

解决方法:

Docker将主机名后的所有内容视为存储库名称(可选择使用命名空间)和标记.
这意味着您只需要使用您分配的端口(2222)和主机名.
上下文路径将成为存储库名称.

在你的情况下,它应该是：

docker tag ubuntu mNginxLb.mycompany.com:2222/ubuntu

docker push mNginxLb.mycompany.com:2222/ubuntu

请注意,最新的标记是隐式的.另一个例子可能是：

docker tag ubuntu：15.10 mNginxLb.mycompany.com:2222/ubuntu:15.10
