设置私有 docker-registry 时出错

Question

使用 the official Docker registry container 我正在尝试运行 AWS EC2 上的私有 docker-registry，但我一直运行ning 连接错误。运行标准容器的命令是：

docker run -d \
         -e SETTINGS_FLAVOR=s3 \
         -e AWS_BUCKET=mybucket \
         -e STORAGE_PATH=/registry \
         -e AWS_KEY=whateffa \
         -e AWS_SECRET=verysecret \
         -e SEARCH_BACKEND=sqlalchemy \
     -e AWS_REGION=eu-west-1 \
     -e STORAGE_REDIRECT=true \
         -p 443:5000 \
         registry

但是当我尝试使用以下方式将本地映像推送到新注册表时：

docker push zite.com:443/test

我得到：

FATA[0014] Error: v1 ping attempt failed with error: 
Get https://zite.com:443/v1/_ping: dial tcp 1.2.3.4:443: i/o timeout. 
If this private registry supports only HTTP or HTTPS with an unknown CA
certificate, please add `--insecure-registry zite.com:443` 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/zite.com:443/ca.crt

我已经在很多地方添加了 --insecure-registry zite.com:443（因为我不确定 docker 守护程序选项的正确位置是：

/etc/sysconfig/docker
/etc/docker/default
/etc/docker/default

为了获得更多细节，我尝试了：

OpenSSL s_client -connect zite.com:443/v1/_ping -prexit -debug

这给了我：

我对此太陌生，无法理解如何解决这个问题。

GETting '_ping' url 工作正常 btw:

curl -v http://zite.com:80/_ping

给出：

* Hostname was NOT found in DNS cache
*   Trying 52.17.133.30...
* Connected to zite.com (1.2.3.4) port 80 (#0)

我已经尝试运行在端口 80、443、500 上连接容器，但无济于事（并在 AWS EC2 机器上打开了这些端口）。错误仍然存在。我还尝试从 github source. I've tried getting an answer at the official repo 构建一个全新的图像，但已经停滞不前，我必须继续前进。

我遵循的许多指南：

好的，找到了。事实证明，您必须使用“--insecure-registry”选项运行本地 docker 守护进程，而不是远程 docker 注册表的 docker 守护进程。
