如何通过反向代理将 docker 个图像推送到 artifactory

Question

我在将 docker 图像推送到人工制品 [Artifactory Pro Power Pack 3.5.2.1（修订版 30160）]（用作 docker 注册表）时遇到问题。

我有 docker 版本：

$ sudo docker version
Client version: 1.5.0  
Client API version: 1.17  
Go version (client): go1.3.3  
Git commit (client): a8a31ef/1.5.0  
OS/Arch (client): linux/amd64  
Server version: 1.5.0  
Server API version: 1.17  
Go version (server): go1.3.3  
Git commit (server): a8a31ef/1.5.0

我关注了这个 link http://www.jfrog.com/confluence/display/RTF/Docker+Repositories and this one 我在名为 docker-local 的 artifactory 中创建了一个 docker 注册表并启用了 docker 支持。我的 artifactory 没有选项，我可以像 this document 中那样说 docker v1 或 v2，所以我假设它使用 docker v1。

Artifactory 为我生成了这些：

<distributionManagement>
    <repository>
        <id>sdpvvrwm812</id>
        <name>sdpvvrwm812-releases</name>
        <url>http://sdpvvrwm812.ib.tor.company.com:8081/artifactory/docker-local</url>
    </repository>
    <snapshotRepository>
        <id>sdpvvrwm812</id>
        <name>sdpvvrwm812-snapshots</name>
        <url>http://sdpvvrwm812.ib.tor.company.com:8081/artifactory/docker-local</url>
    </snapshotRepository>
</distributionManagement>

虽然有些东西不适用于这些设置。

我安装了反向代理 nginx 并将这些设置复制到它的 /etc/nginx/nginx.conf 中：

http {

##
# Basic Settings
##
[...]

server {
    listen 443;
    server_name sdpvvrwm812.ib.tor.company.com;

    ssl on;
    ssl_certificate /etc/ssl/certs/sdpvvrwm812.ib.tor.company.com.crt;
    ssl_certificate_key /etc/ssl/private/sdpvvrwm812.ib.tor.company.com.key;

    access_log /var/log/nginx/sdpvvrwm812.ib.tor.company.com.access.log;
    error_log /var/log/nginx/sdpvvrwm812.ib.tor.company.com.error.log;

    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_set_header X-Original-URI $request_uri;
    proxy_read_timeout 900;

    client_max_body_size 0; # disable any limits to avoid HTTP 413 for large image uploads

    # required to avoid HTTP 411: see Issue #1486 (https://github.com/docker/docker/issues/1486)
    chunked_transfer_encoding on;

    location /v1 {
        proxy_pass http://sdpvvrwm812.ib.tor.company.com:8081/artifactory/api/docker/docker-local/v1;
    }
} }

我生成了我的 ssl 密钥，如 http://www.akadia.com/services/ssh_test_certificate.html 所示，并放置在 2 个目录中

/etc/ssl/certs/sdpvvrwm812.ib.tor.company.com.crt;
/etc/ssl/private/sdpvvrwm812.ib.tor.company.com.key;

我不确定如何 ping 新的 docker 注册表，但是

 sudo docker login -u adrianus -p AT65UTJpXEFBHaXrzrdUdCS -e adrian@company.com http://sdpvvrwm812.ib.tor.company.com

出现此错误：

FATA[0000] Error response from daemon: v1 ping attempt failed with error: Get https://sdpvvrwm812.ib.tor.company.com/v1/_ping: dial tcp 172.25.10.44:443: connection refused. If this private registry supports only HTTP or HTTPS with an unknown CA certificate, please add --insecure-registry sdpvvrwm812.ib.tor.company.com to the daemon's arguments. In the case of HTTPS, if you have access to the registry's CA certificate, no need for the flag; simply place the CA certificate at /etc/docker/certs.d/sdpvvrwm812.ib.tor.company.com/ca.crt

但是证书 /etc/docker/certs.d/sdpvvrwm812.ib.tor.company.com/ca.crt 存在，这是怎么回事？

sudo curl -k -uadrianus:AP2pKojAeMSpXEFBHaXrzrdUdCS "https://sdpvvrwm812.ib.tor.company.com"

出现此错误：

curl: (35) SSL connect error

我开始使用 docker 客户端：

sudo docker -d --insecure-registry https://sdpvvrwm812.ib.tor.company.com

难道是因为我的docker注册表是http://sdpvvrwm812.ib.tor.company.com:8081/artifactory/docker-local并且docker和nginx正在寻找http://sdpvvrwm812.ib.tor.company.com:8081/artifactory/docker-local/v1?

任何线索如何获得 docker 将图像推送到人工制品？

Answer 1

<distributionManagement/> 部分是针对 maven 的。 Artifactory 3 显示 Docker repos 的 maven 代码段（已在 Artifactory 4 中修复，欢迎您升级），这有点面子，所以请忽略它。

通常 Docker 不能使用 /artifactory/repoName。这是 Docker 限制，您的注册表必须是 hostname:port，没有任何其他路径。

这正是您必须配置反向代理的原因。您在 nginx 配置中所做的是将所有请求转发到 sdpvvrwm812.ib.tor.company.com:443/v1 到 http://sdpvvrwm812.ib.tor.company.com:8081/artifactory/api/docker/docker-local/v1，这是正确的做法。

请注意，证书的位置应该是 /etc/docker/certs.d/sdpvvrwm812.ib.tor.company.com/，而不是 /etc/ssl/certs/。
