所以我在使用自己的自签名证书的公司代理服务器后面工作。
我所做的是编辑~/.curlc，以便将其配置为使用我的代理，以及设置环境变量http_proxy和https_proxy。
然后我通过将代理的ca证书移入\etc\ssl\certs并通过ln -s my_ca.pem `openssl x509 -hash -noout -in my_ca.pem`.0创建其哈希的链接来安装代理的ca证书。
所以现在我可以curl和wget，一切正常。
接下来，我创建了目录/etc/systemd/system/docker.service.d，并在其中创建了一个名为http-proxy.conf的新文件：
[Service]
Environment= "HTTP_PROXY=http://user:pass@proxy.corp.net:3128/" "HTTPS_PROXY=https://user:pass@proxy.corp.net:3128/"
在执行docker search工作之后，我仍然无法从官方注册表中提取容器。
systemctl status docker告诉我：Download failed, retrying: x509: certificate signed by unknown authority
所以我真的不知道我能做些什么让它起作用。也许这里有人有想法吗？
