【问题描述】：

我已经创建了自己的私有注册表 (private-registry)，但我无法将图像推送到它。比我得到以下错误：

The push refers to a repository [private-registry:5000/ubuntu] (len: 1)
unable to ping registry endpoint https://private-registry:5000/v0/
v2 ping attempt failed with error: Get https://private-registry:5000/v2/: net/http: TLS handshake timeout
 v1 ping attempt failed with error: Get https://private-registry:5000/v1/_ping: net/http: TLS handshake timeout

运行注册表的日志显示如下：

time="2015-12-14T07:59:21Z" level=warning msg="No HTTP secret provided - generated random secret. This may cause problems with uploads if multiple registries are behind a load-balancer.

我无法卷曲我的注册表（超时）。这是我执行的步骤：

首先我创建了自签名证书：

mkdir -p certs && openssl req \
  -newkey rsa:4096 -nodes -sha256 -keyout certs/domain.key \
  -x509 -days 365 -out certs/domain.crt

我已经创建了我的注册表，它将使用这些证书：

docker run -d -p 5000:5000 --restart=always --name private-registry \
  -v `pwd`/certs:/certs \
  -e REGISTRY_HTTP_TLS_CERTIFICATE=certs/domain.crt \
  -e REGISTRY_HTTP_TLS_KEY=certs/domain.key \
  registry:2

我授予了正确的权限：

chcon -Rt svirt_sandbox_file_t ~certs/

我创建了：/etc/docker/etc.d/private-registry:5000/ 我在里面复制了我的domain.crt。我编辑了我的/etc/hosts 并添加了： 10.0.0.X private-registry（我的内部 ip 和我的注册表名称）

我还重新启动了 docker 和我的注册表。

编辑：

以上关于冰壶的更新
可能刚刚超过请求数量，拉取图像由很多容器组成。请尝试在几分钟后重新运行。

【解决方案1】：

您可能需要将证书放入此目录。

    /etc/docker/certs.d/private-registry.com:5000/ca.crt
