Docker： TLS握手超时

Question

我已经创建了自己的私有注册表（私有注册表），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

正在运行的注册表的日志显示以下内容：

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. To provide a shared secret, fill in http.secret in the configuration file or set the REGISTRY_HTTP_SECRET environment variable." go.version=go1.5.2 instance.id=a77e1955-3688-4fe3-a06e-0341787f8d0f version=v2.2.1

我无法卷曲我的注册表（超时）。以下是我执行的步骤：

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

我已创建注册表，它将使用以下证书：

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/，并复制了我的域。crt在它里面。我编辑了我的/etc/hosts并添加了：10.0。0.X私有注册表（我的内部ip和注册表名）

我还重新启动了docker和我的注册表。

编辑：

您可能需要将证书放入此目录中。

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