Docker推送-Net / http:TLS握手超时 [英] Docker push - net/http: TLS handshake timeout
问题描述
我已在AWS EC2 Ubuntu 14.04实例上部署了私有Docker映像注册表。使用我们的加密证书来保护注册表的安全。
I've deployed a private docker image registry on an AWS EC2 Ubuntu 14.04 instance. The registry is secured using Let's Encrypt certificate.
不幸的是,我收到 net / http:TLS握手超时
进行了超过300秒钟的 docker push
操作:
Unfortunately, I'm getting net/http: TLS handshake timeout
for docker push
operations that take longer than 300s:
这是 timedd
命令的输出:
[luqo33@home-pc containers]$ time docker push <my-registry-domain:5000>/nginx
The push refers to a repository [<my-registry-domain:5000>/nginx]

regsitry:2
容器的日志未显示任何错误-除了接收数据时出现意外的EOF通知。我也可以推送少于5分钟的图片,而不会出现问题。
Logs of the regsitry:2
container do not show any errors - other than the notification that there was an unexpected EOF while receiving data. I can also push images that take less than 5min to push without problems.
我怀疑这是系统设置的罪魁祸首,因为一旦操作进行,超时总是发生超过300秒。没有任何负载平衡器或其他代理。 < my-registry-domain:5000>
直接指向服务器IP。
I'm suspecting that it's a system setting at blame as the timeout happens always once the operations goes beyond 300 seconds. There isn't any load balancer or other proxy. <my-registry-domain:5000>
points directly at the server IP.
如何进一步调查
EDIT
当我按下镜像到其他服务器提供商(DigitalOcean),AWS ECS注册表甚至Docker Hub!我很难相信Docker客户端会有300s的内置握手超时。
The same happens when I push images to other server providers (DigitalOcean), AWS ECS registry or even Docker Hub! I find it hard to believe that the Docker client would have a built-in handshake timeout of 300s.
我在想,也许我应该从以下位置开始寻找解决方案:网络级别-使用我的硬件(无线路由器)或ISP。
I'm thinking that perhaps I should start look for the solution at the network level - with my hardware (wi-fi router) or my ISP.
有人知道这里发生了什么吗?
Anybody has a clue what is happening here?
推荐答案
我遇到了同样的问题,这个问题可能是由于您的互联网连接造成的,我通过将并发上传(下载获取)减少到1来解决。
通过使用以下args:
I got the same issue, this issue is may be from your internet connection, I solved it by decrementing the concurrency uploads (downloads for get) to 1 in dockerd. By using these args:
--max-concurrent-downloads (default: 3) Set the max concurrent downloads for each pull
--max-concurrent-uploads (default: 5) Set the max concurrent uploads for each push
如果带宽较低,则同时上传5张图像可能会导致超时。
uploading 5 images in same time may result a timeout if you have a low bandwidth.
